Defined in 2002, XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable and protocol-independent transceiver for 10G high-speed computer network and telecommunication links. Except for XFP, there are SFP and SFP+ transceivers available for 10G connectivity. These devices plug into a special port on a switch or other network device to convert to a copper or fiber interface. So what is the difference between them? The following passage will provide a satisfying solution to you.
What Is XFP?
XFP is 10 Gigabit transceiver operating at wavelengths of 850nm, 1310nm or 1550nm. This module combine transmitter and receiver functions in one compact, flexible, and cost-effective package. The physical dimensions of the XFP transceiver are slightly larger than the original small form-factor pluggable transceiver (SFP). XFP transceiver modules are available with a variety of transmitter and receiver types including the SR, LR, ER and ZR. The maximum working distance of XFP SR is 300 meters. 10GBASE-LR XFP transceivers have a wavelength of 1310nm and a transmission distance up to 10 km. For example, XFP-10G-L-OC192-SR1 covers a distance of 10km with LC connectors. XFP-10GLR-OC192SR is Cisco XFP 10GBASE-LR/-LW operating at wavelength of 1310nm over singlemode fiber with a links length of 10km. Both 10GBASE-ER XFP and 10GBASE-ZR XFP modules have a wavelength of 1550nm, and the maximum transmission distance of 40km and 80km, respectively.
What Is SFP/SFP+?
SFP is most often used for Fast Ethernet of Gigabit Ethernet applications and can support speed up to 4.25Gbps. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is specified by the SFP transceiver multi-source agreement. The standard SFP transceiver, SFP+ supports speeds of 10Gbps or higher over fiber. The SFP+ product family includes cages, connectors, and copper cable assemblies. It is also similar to the performance requirements of SFF-8431 and also supports 8G Fiber Channel and 10G Ethernet applications. Take 46C3447 as an example, it is 10GBASE-SR SFP+ that can support a distance of 300m over OM3 cable.
What’s the Difference Between XFP and SFP+?
First of all, both of them are 10G transceiver modules and can contact with other types of 10G modules. The primary difference between SFP+ and the slightly older XFP standard is that the SFP+ moves the chip for clock and data recovery into a line card on the host device. This makes SFP+ smaller than XFP, enabling greater port density. Because of the smaller volume, SFP+ transfer signal modulation function, serial/deserializer, the MAC, clock and data recovery (CDR) and electronic dispersion compensation (EDC) function from the module to the Lord on the card. In addition, SFP+ compared to XFP, is a more compact factor package. The cost of SFP+ is also less than that to the XFP, X2 and XENPAK. It can connect with the same type of XFP, X2 and XENPAK as well. Therefore, SFP+ is more popular than XFP for 10G network.
10G optical transceivers are designed for 10G or 10Gbit/s data transmission applications including 10 Gigabit Ethernet, 10Gbit/s Fibre Channel, Synchronous optical networking. After years of development, there has been various different form factors and optics types introduced including XENPAK, X2, XFP and SFP+. But up to now, SFP+ is the most commonly used 10G transceivers available on the market. fiber-mart provides a large selection of 10G transceivers with minimum price and high quality.

Ethernet as the networking standards, enables computers to locally connect to each other, which is the ultra-strong backbone to the many networks we use every day. Although most of the Ethernet market is still running around 1 Gbqs or 10 Gbqs, there is a strong interest in higher data rates. Many hardware vendors like Cisco, Finisar, Huawei and Brocade have recently announced support for 100 Gigabit Ethernet and telecom vendors around the world have also shown interest in launching 100G networks. All these events shows the sign of the advent of 100 Gigabit Ethernet in the commercial segment. However, is it necessary to move to 100G now? Or should the 100g migration be a smooth one just as the IEEE has made when moving to 40G? This article will highlight the reasons and solutions of upgrading to 100G.
Why Move to 100G?
Most enterprises today are encouraging telecommuting and promote real-time, high-definition, high-quality voice and video solutions. All these require a huge bandwidth capacity. Additionally, 100G implementations offer an effective means to operate seamlessly within an existing 10G network infrastructure, avoid the need for additional optical amplifiers, dispersion compensators or regenerators. 100G is today’s choice to scale networks in a way that delivers the required capacity in the most efficient manner, readying the network for tomorrow’s bandwidth crunch.
Another interesting point is the efficiency of 100G Ethernet compared to link aggregation that is used today. As of now, a 10 x 10G Ethernet link aggregation can not give a throughput of up to 100 Gbps. This limitation can be overcome with a true 100G connection which can give a 100Gbps bandwidth, thus allowing high capacity links to scale even further. Considering all these, if not this year or the next, 100G will be widely adopted soon.
Last but not the least, the industry have come together in order to create a healthy 100G ecosystem, which will be beneficial for the entire community. This broad inclusion will result in a fast introduction of 100G solutions that will meet industry performance, size, cost, and power requirements. If the cost drive is right, once 100G is standardized and commercially available, network operators will quickly capitalize 40G investments and adopt 100G transmission for their future deployments.
Migrate to 100G with 100G Transceiver Modules
There are several form factors for supporting 100GbE including CFP, CFP2, CFP4, QSFP28 and CPAK. The following will make a clear introduction to all of them.
The CFP is the very first 100G transceiver for the transmission of high-speed digital signals, the C stands for the Latin letter centum (means 100). The CFP module was designed after the SFP interface, but is significantly larger to support 100 Gbqs using 10 x 10 Gbit/s lanes in each direction (RX, TX). The optical connection can support both 10 x 10 Gbit/s and 4 x 25 Gbit/s variants of 100 Gbit/s interconnects. There are four common types of CFP transceiver modules, such as 100GBASE-SR10 in 100 meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10 km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40 km SMF reach respectively.
As improvements in technology have allowed higher performance and higher density, which drives the development of the CFP2 and CFP4 specifications. While CFP, CFP2 and CFP4 are electrical similar, they specify a form-factor of 1/2 and 1/4 respectively in size of the original specification. Note that CFP, CFP2 and CFP4 modules are not interchangeable, but would be inter-operable at the optical interface with appropriate connectors.
QSFP28 is the same footprint as the 40G QSFP+ module. Just as the 40G QSFP+ module is using four 10Gbps lanes, the 100G QSFP28 is implemented with four 25Gbps lanes. In all QSFP versions, both the electrical lanes and the optical lanes operate at the same speed, eliminating the costly gearbox found in CFP, CFP2, and the CPAK. The QSFP28 module has an upgraded electrical interface to support signaling up to 28Gbps signals, yet keeps all of the physical dimensions of its predecessor. As QSFP28 technology becomes even maturer, QSFP28 transceivers will become more and more popular in 100G optics market. The above image shows a QSFP-100G-SR4-S. it is Cisco 100GBASE-SR4 QSFP28 transceiver module.
100GBASE-SR4 QSFP28 transceiver and 100GBASE-LR4 QSFP28 transceiver are the two main types of the QSFP28 transceivers. The former is specified to operate over multimode fiber (MMF) with the maximum link length of 70m on OM3 and 100m on OM4, while 100GBASE-LR4 QSFP28 is standardized to work through single-mode fiber (SMF), able to realize 10km link length.
QSFP28 vs. CFP
QSFP28 and CFP are the two common 100G optical transceivers available on the market. As noted before, CFP is the first-generation 100G transceiver. It is the common scene that QSFP28 makes an appearance and CFP takes a bow, which reflects the trend in the industry to aggressively bring 100GE density up and costs down. CFP4 is half the width of CFP2, which is half again the width of CFP. QSFP28 has the same footprint and faceplate density as QSFP+ and is just slightly smaller than CFP4. Theoretically, QSFP28 seems to have the density advantage over CFP4, but CFP4’s higher maximum power consumption gives it the advantage on longer reach optical distances. However, the CFP is much more expensive than QSFP28 and will not be used for lower speeds because of the high cost.
CPAK is another newcomer to supporting 100G network. This is a proprietary form factor from Cisco but the interfaces demonstrated are IEEE standards and will interoperate with the same interfaces supported by other form-factors. Together, these solutions will deliver the smallest form-factor, most efficient 100-Gbps optical transceiver portfolio in the industry. Cisco CPAK will be available in several IEEE-standard optical interfaces.
Within the next several years, 100G is doom to become the dominant backbone technology in terms of its high capacity over 10G and surpassing would-be high-speed contender 40G. Of course, we must count on the components and systems suppliers to build products that meet technical and economic requirements while allowing a smooth migration to the 100G infrastructure that is being put in operation today. Fiberstore as a rising telecom supplier, is committed to promote telecommunication development. We recently release a full range of 100G optical transceivers including CFP, CFP2, CFP4, QSFP28 and QSFP28 DAC cables. All of our products are fully compatible with the original brand. If you have any requirement, you can send your request to us.
For the data center or network upgrade, 40G network is a trending choice. Then where do you buy the 40G QSFP transceiver? Will you choose an OEM one or a third-party one? There are some differences between third-party 40G QSFP transceiver and OEM 40G QSFP transceiver, which will be shown below.
Features of OEM 40G QSFP Transceiver Modules
As we know, the OEM 40G QSFP transceiver from name brand like Cisco, Juniper and Brocade is widely used in data center and enterprise network. They all have some great features. The Cisco 40G QSFP transceiver offers a wide variety of high-density and low-power 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications. Here are some benefits of Cisco 40 Gbps transceiver:
Hot-swappable input/output device that plugs into a 40 Gigabit Ethernet Cisco QSFP port
Flexibility of interface choice (for different reach requirements and fiber types)
Interoperable with other IEEE-compliant 40GBASE interfaces where applicable
Certified and tested on Cisco QSFP 40G ports for superior performance, quality, and reliability
High-speed electrical interface compliant to IEEE 802.3ba
QSFP Form factor, 2-wire I2C communication interface and other low-speed electrical interface compliant to SFF 8436 and QSFP
The Brocade 40 Gbps transceiver supports highly reliable operations in data center and is optimized for Brocade switching platforms. It undergoes strict qualification and certification testing.
Why Choose 3rd 40G QSFP Optical Transceivers Over OEM?
40G QSFP transceiver from Cisco and Brocade is reliable and with high-quality, but why so many third-party 40 Gbps transceiver occurred on the market? The answer seems simple, the transceiver market need it. With high-speed development of the optical communication industry, the demand for 40G QSFP transceiver is increasing. The third-party 40G QSFP with good compatibility and high stability is the perfect choice for some customers. Here are some amazing advantages of the third-party 40 Gbps transceiver:
Optics that you buy directly from name brand is expensive because it includes the costs of testing and validation, and the majority of what you pay for goes into their pocket as pure profit. While the third-party providers may not use the same testing procedures as the name brand, but most have nearly 100% success in compatibility. The third-party providers don’t mark up the 40G QSFP as much as the name brand, so they offer better price for the customer.
Quality and Reliability
The third-party 40Gbps transceiver is reliable as the original one if you buy from a reliable optics provider. Usually, the reliable third-party provider will offer warranty and support after you buy from them, because they are highly focused and specialize in the optical transceiver market.
More choice for 40G QSFP transceiver
The third-party optical transceiver is compatible for most name brand transceivers, so it will have more choice for your data center and enterprise networks.
For the 40 Gbps transceiver, fiber-mart.COM provides various of compatible brands for you, Cisco, Genetic, Juniper Networks, Arista Networks, Brocode, HPE, Dell, Intel, IBM, etc. All have passed the compatibility testing.
After the comparison, will you choose the third-party 40G QSFP transceiver? Using third-party optics instead of name brand optics is a smart and innovative way to embrace changes in the dynamic networking and date center hardware markets. fiber-mart.COM will be you good choice with good compatibility, support offerings and great reputation.
As the core of optoelectronic device in the WAN, MAN or LAN application, fiber optic transceivers have developed various types along with the increasing in complexity. Take 10G transceiver module as an example, it has experienced developments from XENPAK, X2, XFP and finally realized with SFP+. Many users raised the questions related to the main difference between these optical modules. So, in the following part, we will provide some main tips about the difference among the XENPAK, X2, XEP and SFP +.
Four Transceiver Modules—Description & Comparison
Those four transceivers (see in Figure 1) are all used to transmit 10G signal using Ethernet protocol. They are the result of Multi-Source Agreement (MSAs) that enable vendors to produce 802.3ae-compliant pluggable transceivers. The following part will provide a general guide to these module types.
X2—the successor to the XENPAK (the smaller brother of the XENPAK). Presents SC connectors
XFP—the first of the small form factor 10GbE optics and newest pluggable transceiver. Presents LC connectors
SFP+—a 10GbE optics using the same physical form factor as a gigabit SFP. Because of this, many of the small SFP+ based 10GbE switches use 1G/10G ports, giving an added degree of flexibility. Presents LC connectors.
The first published XENPAK was by far the largest in physical size, which totally limited its popularity on the market. Many vendors then began to work on alternative standards. Finally in 2003, MSAs published another two 10G transceiver modules called X2 and XFP. X2 and XFP modules have been developed that support all of the high-power, long-distance applications once reserved for the larger XENPAK transceivers. But nowadays, SFP+ has gradually replaced the XFP and becomes the main stream of 10G transceivers markets. Why? The following part will answer you.
Contrast Between XFP and SFP+
XFP modules are hot-swappable and protocol-independent. They typically operate at near-infrared wavelengths of 850nm, 1310nm or 1550nm. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques. SFP+ published on May 9, 2006, is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format supported by many network component vendors. Although the SFP+ standard does not mention 16G Fibre Channel, it can be used at this speed.
Both SFP+ and XFP are 10G transceivers, and can connect with other 10G transceivers. The main reason why SFP+ gain more market share than XFP is that SFP+ is more compact sized than XFP. The smaller SFP+ transfers the modulation functions, serial/deserializer, MAC, clock and data recovery (CDR) and EDC functions from the module to the motherboard on the card. In addition, cost of SFP+ is lower than XFP. Because XFP relies on a high-speed interface (10.3125Gbps), high-priced serializer/deserializer (SERDES) is required inside the switch to support it. They add an unacceptable cost to the base system of XFP. XFP complies with protocol of XFP MSA while SFP+ complies with IEEE802.3, SFF-8431, SFF-8432. SFP+ is the mainstream design currently.
SFP+, with its advantages of smaller size, low-cost and meeting the demand of high-density fiber transceivers, is anticipated to give rise to the realization better speed communication networks of the next generation. fiber-mart.com, as a professional optical transceiver modules manufacturer, supplies a complete range of 10G transceiver modules that can be customized as well.

SFP (small form-factor pluggable) transceivers, as one of the most useful technological advancements on the market are warmly welcomed by subscribers. These transceivers are some of the most reliable devices in the market because the designs are derived from a multi-source agreement (MSA) and are a pluggable form of SFF. They are hot-swappable, which is highly beneficial to designers in the industry. Besides these helpful information, here are some things you need to know about SFP transceiver modules.
Types of SFP Transceivers
SFP transceivers are available with a large amount of transmitter and receiver types. Customers can select the appropriate transceiver to provide the required optical reach over multi-mode fiber (MMF) or single-mode fiber (SMF).
Optical SFP module is commonly offered in several different categories: SX, LX, ZX, 1000BASE-T, and DWDM, etc. Each category supports a different distance that will transmit data both upstream and downstream. For instance, the SX model will transmit for 10 km, ZX will transmit up to 80 km and DWDM transceiver will achieve various distance at various wavelengths. Take Cisco SFP as an example.
For copper twisted pair cabling
Cisco 1000BASE-T SFP module (Cisco GLC-T) operates on category 5 unshielded twisted-pair copper cabling of link lengths up to 100 m.
For multi-mode fiber
GLC-SX-MMD operates on 1000BASE-SX standard links up to 550 m
Where Transceivers Are Used?
Most SFP transceivers can be found in popular networking systems such as Wide Area Networks (WANs), Metro Access Network, and Metro Core Network. SFP transceivers support fiber networking standards such as Fibre Channel, SONET, and Gigabit Ethernet. They also support a variety of other communications standards as well. A compact and hot-swappable optical transceiver can be used in all types of optical communications and telecommunications applications. These devices will connect a switch, router, or other network device.
Advantages of an SFP Transceiver
SFP transceiver is hot-swappable, which make it easy to change and easy for maintenance compared with traditional modules. SFP transceiver modules make the fiber optic network or fiber-Ethernet network easier to upgrade or maintain users can replace a single SFP module during the process instead of replacing the whole board with many modules on it.
Digital optical monitoring (DOM) is based on the new and modern optical transceiver design. Consumers have the ability to monitor real-time parameters of the SFP module. Optical inputs and output power, laser bias, and supply voltage will allow designers to monitor real-time.
In addition, A SFP transceiver is capable of transferring data rates up to 4.25 Gpbs. The XFP form factor is similar to the SFP type. But compared to XFP (10 Gigabit Small Form Factor Pluggable) transceiver, the functionality of SFP module increases about three times at 10 Gpbs. SFP transceivers have a higher optical reliability and will permit higher soldering temperatures. SFP transceivers are recommended by fiber optic component providers to ensure proper data transmission.
SFP modules are some of the best in the industry and will ensure that your design operates at full capacity with low failure rates. This article mainly analyzes three expects of SFP transceiver modules, namely the category of SFP module, application and advantage. fiber-mart.com offers an exceptional amount of SFP modules that are fully compatible with major brand (Cisco, HP, Finisar, Juniper, etc.). Not only GLC-SX-MMD, GLC-ZX-SMD, DS-SFP-FC8G-SW and EX-SFP-1GE-SX, but also GLC-T SFP are all available in fiber-mart.com. I cannot list all the compatible SFP transceivers here. If you are interested, you can contact us directly.
The widely acknowledged Ethernet speed upgrade path was 10G-40G-100G. However, a new development indicates the latest path for server connection will be 10G-25G-100G with potential for future upgrading to 400G. But why 25G? Because moving from 10G to 40G is a big jump and it turns out the incremental cost of 25G silicon over 10G is not that great. This new standard will require improved cables and transceiver modules capable of handling this additional bandwidth, under this circumstance, QSFP28 and SFP28 are promoted.
25GbE Ethernet—An Emerging Standard
25 Gigabit Ethernet (25GbE) has passed the first hurdle in the IEEE standards body with a successful Call for Interest (CFI) in July, 2014. It is a proposed standard for Ethernet connectivity that will benefit cloud and enterprise data center environments. 25GbE leverages technology defined for 100 Gigabit Ethernet implemented as four 25-Gbit/s lanes (IEEE 802.3bj) running on four fibers or copper pairs. The follow picture shows 25G Access Network.
Significant Performance Benefits—25G Over 40G
The value of 25GbE technology is clear in comparison to the existing 40GbE standard. Obviously, 25GbE technology provides greater port density and a lower cost per unit of bandwidth for rack server connectivity. For applications that demand substantially higher throughputs to the endpoint, there exists 50GbE—using only two lanes instead of four—as a superior alternative to 40GbE in both link performance and physical lane efficiency.
The proposed 25GbE standard delivers 2.5 times more performance per SerDes lane using twinax copper wire than that available over existing 10G and 40G connections. A 50GbE link using two switch/NIC SerDes lanes running at 25 Gb/s each delivers 25% more bandwidth than a 40GbE link while needing just half the number (four) of twinax copper pairs. Therefore, a 25GbE link using a single switch/NIC SerDes lane provides 2.5 times the bandwidth of a 10GbE link over the same number of twinax copper pairs are used in today’s SFP+ direct-attach copper (DAC) cables.
Perhaps the most important benefit of 25GbE technology to data-center operators is maximizing bandwidth and port density within the space constraints of a small 1U front panel. It also leverages single-lane 25Gb/s physical layer technology developed to support 100GbE.
Cloud Will Drive to QSFP28 and SFP28
QSFP28 is used for 4x25GE and SFP28 is used for a single 25GE port. SFP28 module, based on the SFP+ form-factor, suports the emeraging 25G Ethernet standard. It enables error-free transmission of 25Gb/s over 100m of OM4 multi-mode fiber and a new generation of high-density 25 Gigabit Ethernet switches and network interface cards, facilitating server connectivity in data centres, and a conventional and cost-effective upgrade path for enterprises deploying 10 Gigabit Ethernet links today in the ubiquitous SFP+ form factor.
The QSFP28 (25G Quad Small Form-Factor Pluggable) transceiver and interconnect cable is a high-density, high-speed product soluon designed for applicaons in the telecommunicaons, data center and networking markets. The interconnect offers four channels of high-speed signals with data rates ranging from 25 Gbps up to potentially 40 Gbps, and will meet 100 Gbps Ethernet (4×25 Gbps) and 100 Gbps 4X InfiniBand Enhanced Data Rate (EDR) requirements.
The demonstration showed QSFP28-SR4 modules and a compatible Finisar FTLX1471D3BCL 10GBASE-LR SFP+. The QSFP28 SR4 module is a vertically integrated solution that meets IEEE 802.3 standards and MSA requirements with power dissipation well under 3.5W. The module supports both 100GBASE-SR4 as well as 4x25G breakout applications. Both the QSFP28 SR4 and SFP28-SR modules are sampling now.
The dominant next-generation server connection speed is going to be 25G as it providing a cost competitive longer reach option for mainstream customers. fiber-mart.com is excited to introduce several products that will drive the next generation of data centre and enterprise interconnects.

An optical fiber cable uses light wave for voice and data transmission, its data transmission capacity is 4.5 times more than conventional copper cables. So in the past several decades, we have seen that fiber optic cables are superior to traditional copper twisted-pair cable or coaxial cable because of its unique physical characteristics, allowing information to travel at speeds increasingly approaching the speed of light without interference between adjacent wavelengths. In leading market, the global drive to implement FTTx into more new venues is good news for the market of optical fiber cables. Another good trend is that the price erosion of optical fiber cables had been 10 to 15 percent annually, in result that the demand of optical fiber cable is expected to continue growing in the foreseeable future. And the growing data transmission workloads placed by high-performance computers, servers and network storage systems is helping spur growth in the market. Consequently, fiber optic cables are now the indispensable backbone of today’s communication network. This article will analyse the global optical fiber cable market in three main applications, including long-distance communication, submarine cable and FTTx network.
Global Optical Fiber Cable Market to Grow at 9.8% till 2021
According to the report “Fiber Optics Market by Cable – Global Forecast to 2021”, the optical fiber cable market is anticipate to grow at a CAGR of over 9.8% during 2016-2021. The growing importance of cloud computing, data transfer & storage, and IoT is driving the use of Internet, which is driving the fiber optic cable market, as it acts as the backbone for data transmission. Moreover, growing technological advancements increase in number of connected devices and data centers are expected to positively influence global optical fiber cable market. In addition, next generation technologies such as LTE and FTTx, which require last mile connectivity, is expected to propel the demand for optical fiber cables in the coming years. All these factors have led to an increase in Internet users, which in turn has led to the higher usage of optical fiber cable to transfer information over the Internet, thus driving the fiber optics market.
Optical Fiber Cable Market in Long-distance Communication
Currently, the growing adoption of optical technology in the telecommunications appears to be promising. Optical fiber has virtually unlimited capacity and low signal attenuation allowing long distances without amplifier or repeater, no exposure to parasite signals or crosstalk, and no electromagnetic interference (EMI). So fiber optic cable is especially advantageous for high-speed data transfer services in long-distance communications over electrical cabling. Furthermore, the increasing cloud-based applications, audio-video services, and Video-on-Demand (VoD) services further stimulate the demand for optical fiber cable installations.
Submarine Optical Fiber Cable Market
Submarine optical fiber cables are undersea cables used for carrying data across interconnected networks between continents. With the advancements of technology, most of the submarine optical fiber cables that currently form the backbone of the Internet connect the U.S. to Europe and Asia by crossing the Atlantic or Pacific oceans. Instead, there is a proposal for deployment of Trans-polar submarine cable system in Arctic Ocean. Laying an undersea fiber optic cable is meant to connect Asia and Europe by crossing the Arctic Circle – the shortest practical distance yet for Internet signals traveling between the two continents. According to the report by Global Industry Analysts (GIA), cumulative installations of submarine optical fiber cables globally are projected to reach 2 million kilometers by 2020, driven by the growing demand for fiber broadband and the ensuing deployment of fiber optic cables in the Internet backbone. Presently, submarine optical fiber cables transmit 100% of the international Internet traffic, and more than 95% of the world’s combined data and voice traffic.
Optical Fiber Cable Market in FTTx Networks
In recent years, the market for optical fiber cable has shifted dramatically to local deployments, away from long haul and regional. This is the impact of FTTx, which calls for far more dense applications in neighborhoods, cities and other highly focused areas. Optical fiber cable is being caught up in the global move to broadband in the near future. The next generation of high bandwidth applications, along with the proliferation of connected devices, is expected to require faster and higher bandwidth networks which will require the use of multimode fiber cable for data transfer. This growth in the FTTx networks in turn is expected to drive the fiber optics market. Future Market Insights (FMI) forecasts the global fiber to the home (FTTH) market’s value will grow from $9.5 billion in 2017 to more than $37 billion by the end of 2027, a 14.4% compound annual growth rate (CAGR). In the leading Asian economies, more than 44% of all homes and buildings are already directly connected to the fiber optic cable network; in North America penetration is 8.4%, in Europe 5.6%.
Fiber optic cable is widely used for data transmission and is increasingly being used in place of metal wires because of its efficiency and high transmission capacity. Since the use and demand for great bandwidth and fast speed, there is no doubt that fiber optic transmission will bring more opportunities and be continuously researched and expanded to cater for future demands. However, although fiber optic cable in itself is considered a long-term stable investment, it also faces huge challenge. The major restraint in the fiber optics market is the growing use of wireless communications systems in remote areas.
