Will CPAK 100G Transceiver Module Thrive in 2020？

Currently, prices on 100G optical transceivers have been dropping faster than those devices at 40G, which drives customers to migrate to 100G directly instead of turning to the intermediate 40G Ethernet. For example, QSFP-40G-SR-BD ($300) costs higher than QSFP-100G-SR4-S ($269) at fiber-mart.COM. It is the same case as other vendors. QSFP28 and CFP optical transceivers as the main transmission media of 100G network, dominate 100G hardware market.
CPAK, released right after CFP2 100G modules, is the Cisco proprietary form factor, which greatly effect the popularity of this module type. However, in 2017, many third party optical solution vendors like fiber-mart.COM announce to help market to cut down this pricing and save budgets for services providers and operators. So will it thrive in 2017? Today’s article will describe CPAK 100G module in detail attached with the positive analytics of the future of this module type.
CPAK 100GBASE optical module, designed as a smaller, low-cost alternative to CFP transceiver, can be plugged into the CPAK ports of Cisco switches and routers. Besides, CPAK module is the first 100G optical transceivers that use CMOS Photonics technology. This type of 100GBASE modules can work in the following Cisco networking equipment—ASR 9000 Series Router; CRS-X Carrier Routing System; NCS 2000, 4000, and 6000 Series Routers; the Nexus 7000 and 7700 Series Switches, and the Cisco ONS Transport Platform.
CPAK optical transceiver incorporates IEEE standard interfaces available in several different types: 100GBASE-SR10, 100GBASE-ER4L, 100GBASE-LR4, 10x10G-ERL, 10x10GBASE-LR, etc. CPAK transceivers can support 10X10Gbps and 4X25Gbps mode for an aggregate of 100Gbps data rate. It can also operate high-density 10G breakout with MPO-24 cables. CPAK-100G-SR10 is backward compatible with 10GBASE-SR. While CPAK 10X10G-LR is compatible with 10GBASE-LR optics. CPAK LR4 module is compatible with other 100GBASE-LR4 compliant modules such as CFP to support high-bandwidth 100Gb optical links over standard single-mode fiber terminated with SC connectors. Table 1 shows the existing Cisco 100G CPAK Modules.
CPAK Out-Competes CFP/CFP2 for Smaller Footprint & Energy Economy
Once the CPAK transceiver module had been released, it was marked as the smallest 100G footprint providing higher-port density and low power consumption for 100G networks. When comparing with CFP modules, CPAK transceivers are less than one third the size of CFP modules, and dissipate less than one third the power. In a comparison with CFP2 modules, CPAK optical transceivers are 20% smaller and consume 40% less power. In other word, if you use CPAK other than CFP2 modules in your data center switches, it can offer 20% greater port density and front-panel bandwidth.
To sum up, CPAK optical module has smaller footprint than CXP, CFP and CFP2, but bigger than CFP4 and QSFP28 optics. Besides, CPAK 100GBASE-LR4 consumes less than 5.5W, which is less than CFP LR4 (24W), CFP2 LR4 (12W), CFP4 (9W) and CXP LR4 optics (6W) but a little higher than QSFP28 (3.5W). CPAK represents a significant advancement in optical networking, providing dramatic space and power efficiency.
CPAK Vs. QSFP28
QSFP28 optical transceiver is regarded as the most promising 100G optical module due to its smallest form factor and lowest power consumption. For example, Cisco CPAK 100GBASE-LR4 module supports link lengths of up to 10 km over standard single-mode fiber with SC connector with a nominal power consumption of less than 5.5W. QSFP28 100GBASE-LR4 supports up to 10km and consumes nearly 3.5W. CPAK optics obviously don’t have a shot when competing with QSFP28 optical transceivers.
What About the Future of CPAK Modules?
In 2017, 100G technology and relevant optical transceivers gradually become mature. 100G optics like CXP, CFP/CFP2/CFP4, 100G QSFP28 in different standards offers a huge selection for customers. Of which QSFP28 100G modules, thanks to the smallest form factor and reliable performance, maintain large market share in 100G hardware market. In addition, some newly released 100G switches only have QSFP28 ports which in turn promotes the popularity of 100G QSFP28 transceivers.
In such a fierce market environment, it is hard to say whether CPAK will be a hot star in 100G hardware market or not. Anyhow—CPAK module is the first optical transceivers that use CMOS electronic technology. Furthermore, Cisco and several other vendors offer CFP2 to CPAK adapter to support the conversion between CPAK and CFP2 modules. Third party vendors like ourselves are also beginning to supply 100G CPAK modules in 2017. We will see if such industry development will take place!
Summary
CPAK module was launched just days after the certification of CFP2 optics. It is popular for the smaller footprint and energy economy. However, when competing with open source MSA compatible 100G products (CFP/CFP2/CFP4 and QSFP28), CPAK is not the ideal one for 100G high-density connectivity.

How to Buy The Optical Transceiver Module On The Market

What you can choose from the market, several small plug an optical module and network. Receives both an optical signal which is transmitted to the optical transceiver module.
All optical transceiver module, it is necessary to create and along the lines of the multi-source. Make sure that the specialist modules are placed in close coordination. Searching for the trend can be seen when the optical transceiver module can be considered as a group of the speed of transfer rate. Each module of the plug is different from the support of 1 Gbps to 10 Gbps. You can check what you should do great work is to be supported modules, courses.
You can find a variety of actions optical modules with different speeds and range. Modules XENPAK, XFP modules, X2 modules, GBIC, SFP +, SFP, XFP and there is a BiDi plug. Here you will find more information about a few things. For example, a 10g XFP transceiver BiDi road is constructed series for bidirectional optical communication 10G serial data, such as the IEEE 802.3ae 10GBASE-BX as to a transmitter 1330 of 1270 nm, 1270 nm, and the receiver (1330). Transmitting transceiver is configured into two sections with a multi-quantum-well 1330 (1270) nm DFB laser, and assessment at the International Standard IEC 60825 based 1 laser safety compliant; Receiver with built-in limit to the optical head 1270 (equipped 1330) used nano-detector preamplifier (IDP).
GBIC module is an Ethernet network, for example, is also connected to the optical fiber network, and a function as a special work. GBIC GBIC means and the other plug in the connector and the fiber optic cable is used to connect the Ethernet port. If the GBIC is hot-plug provides the ability to mix different types of interfaces without turning. Optical power and wavelength of the working distance and the determined transmission rate, set the specific group in the GBIC module.
The new generation modules can be used as a GBIC transceiver. Stands for Small Form Factor Pluggable SFP modules are hot-pluggable optics. Hot-pluggable transceivers are usually easily change compared to base interface module at regular intervals. These factors such as Cisco SFP is only about half a small tendency for large optical GBIC module + this can .SFP 10 Gbps rates of significant charges modules ranging from about 4 + Gbps to 100 Mbps to send to send. This module will notice that the transfer of approximately 500 m to 120 + km.
It is known that most XENPAK optical transceiver module of the copper lines, including multi-mode fiber optic cable and the single-mode optical fiber cable has a variety of different line of work XENPAK module. 300 m at maximum working distance of multimode fiber of about 15 m after the copper line is typical behavior. Most of the individual module is the first product in accordance with the maximum spanning up to 80 km. Multisource a plug light teuraensibeoyi 10Gbps.
Search What kind of optical transceivers on the market, you should know that you pursue the highest standards in order to make the item. Depending on the fiber optic network experience, you can easily be bought in the market for fiber optic patch cord fiber media converter, like other technical things.
