DWDM SFP Transceiver and WDM SFP Transceiver Overview

SFP (small form-factor pluggable) is a compact, hot-pluggable transceiver used for both telecommunication and data communication applications. It interfaces a network device mother board to a fiber optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fiber Channel, and other communications standards.
Dense Wavelength Division Multiplexing (DWDM) optical transceivers provide DWDM transport to greatly reduce the power consumption and the cost of standard pluggable small form-factor pluggable (module) package. Our SFP DWDM Transceiver is available in all 100 GHz C/L-band wavelength division multiplexing International Telecommunications Union. Their aim was to Multi-Source Agreement (MSA) standards to ensure compatibility with the majority of network equipment.
As a multi-rate interface, SFP DWDM Transceiver supports any protocol from 100 seconds to 4.25 seconds. The module is hot-pluggable and digital diagnostic functions via a serial bus specified Maritime sff-8472 program.
Gigabit Ethernet standard to meet the requirements of the module IEE E802.3 standard specifications and Fiber Channel interconnect, they are suitable for the environment in Gigabit Ethernet and Fiber Channel. A characteristic of DWDM is the specified standard g.692 and g.694.1 of fully compatible with the wavelength parameters.
SFP Bidirectional (BIDI) optical transceivers utilize innovative wavelength division and packaging technology to transmit and receive optical signals through only one single fiber (single mode or multimode). SFP BIDI Transceiver is a high performance, cost effective module, which is compliant with LC/SC Optics interface with built in WDM for Bi-Directional serial optical data communication applications and Standard AC coupled CML for high speed signal and LVTTL control and monitor signals. The deployment of BIDI optical transceivers instantly doubles the bandwidth capacity of the existing optical fiber infrastructure.
Our SFP BIDI optical transceivers also comply with Small Form Pluggable (SFP) Multi-Source Agreement (MSA). SC connector interface is also available upon special request.

Why Should You Choose Compatible Optical Transceivers?

When setting up your network, the selection of devices is fundamental to determining the performance of the system. But those devices can’t communicate without optical transceivers. If your network contains Cisco or Juniper routers, firewalls, and switches, you might assume that with such branded optics only is sensible, to make sure that all of your devices are compatible and processes optimally. However, that seemingly reasonable assumption could cost your company thousands of dollars.
Compared to the compatible units produced by third (3rd) party companies, the transceiver units come with dramatically inflated prices. Compatible units are roughly 80 percent less than the branded optics.
 Why Should You Choose Compatible Optical Transceivers?
Let us take the Cisco compatible SFP transceiver modules for example. Cisco compatible SFPs are simply a great throughout deal. Not many situations are this easy. So don’t get this to difficult on yourself. There is really only something you want to keep in mind. Buy 3rd party OEM compatible SFPs. By collecting Third party OEM compatible SFPs and GBICs you are receiving the very same brand new SFP or GBIC you want. You just get to pay much less for this.
Imagine this. You’re in a dealership and spot a fresh $200,000 luxury car. It’s beautiful – a mighty impressive machine. If someone walked to the car and covered the brand name from the car using their hand, will it be less of the machine? Now imagine somebody suggesting that you could pay $40,000 for that car, however the brand’s lettering could be removed. Can you take the deal? Or can you pay the full $200,000 just to add the brand labeling?
This is basically the situation you face when you decide to purchase Cisco compatible SFPs, but on the smaller scale. With time these costs can definitely equal to big money. It begs the question: What could you use the cash it will save you with time? That’s your decision.
Of course, price isn’t everything. You need to know that you’re getting your money’s worth. That requires a comparison of the items the branded optics has to give you next to 3rd party compatible units.
The lower cost is only one of the benefits of choosing optical transceivers. There are other reasons for you to definitely get this to choice. For example, in a scenario where gigabit speed is needed to stumble upon a point-to-point link, the length between your link lengths is assessed and an appropriate SFP transceiver module native to the host device is chosen.
If a Cisco platform was at situ then your choice of module would be restricted to one of the following 550m (GLC-SX-MM), 10km (GLC-LH-SM), 40km (GLC-EX-SM) or even the maximum 70km (GLC-ZX-SM). With a Cisco compatible SFP transceiver you can choose from the number of distance limits from 550m up to 100km in a variety of increments with distances of 160km being achievable on the top products. Think about this and you would certainly choose the compatible SX SFP transceiver to replace the Cisco GLC-SX-MM and the 10 Gigabit SFP+ to replace the Cisco SFP-10G series.
Another advantage offered solely on compatible optical transceivers is the freedom to tailor the transceiver to your individual requirement. The third party companies such as us Fiberland, can offer all of you the customized specifications around the optical transceivers.
Custom serial numbers could be added both to the product label and also hard coded to the device itself.
Customer Logos can be put into the device.
Latches could be color coded for top density link identification.When setting up your network, the selection of devices is fundamental to determining the performance of the system.

What do you know about CWDM SFP transceivers?

CWDM SFP (Coarse Wavelength Division Multiplexing) transceiver, used on SFP ports or slots on the switches or routers, is a technology that allows for multiple channels, of mixed protocols and data rates, to be COMBINED and transmitted over fiber optic cable.
CWDM SFP makes use of the SFP interface to connect the apparatus and also double LC/PC fiber connector software to connect the optical network. CWDM SFP is used to link the ports to the fiber optic network, typical CWDM SFP like Cisco’s could support both Gigabit Ethernet and Fiber Channel. It is compatible with Fast Ethernet, SONET OC-3 and OC-12, and SDH STM-1 and STM-4 standards.

Structure of CWDM SFP transceiver
The CWDM SFP transceiver consists of three sections: a uncooled CWDM DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit.
The transceiver integrates the receiver and transmitter path on one module. On the transmit side, the serial data stream is passed to a laser driver. The laser driver biases and modulates an uncooled direct modulated laser (DML), enabling data transmission over single-mode fiber through an industry-standard LC connector. On the receive side, the optical data stream is recovered from a PIN or avalanche photodetector (APD), sent to a transimpedance amplifier, and then passed to a post amplifier. This module features a hot-pluggable SFI-compliant electrical interface.
This integrated fiber optic transceiver provides a high-speed serial link at signaling rates from 100 Mbps to 3.1Gbps. The module complies with the small form factor pluggable (SFP) multisource agreement (MSA).

10G Ethernet SFP+ Vs. 10G Fibre Channel SFP+

Today’s technology presents unprecedented migration incorporating a wide range of application requirements such as database, transaction processing, data warehousing, integrated audio/video, real-time computing, and collaborative projects. Fibre Channel and Gigabit Ethernet, both are the ideal solutions for IT professionals who need reliable, cost-effective information storage and delivery at fast speeds. Fibre Channel is available in 1G/2G/4G/8G/16G FC and 10GFCoE, 40GFCoE and 100GFCoE nowadays. Gigabit Ethernet is the reigning network for data center and server room. The battle between Fibre Channel and Ethernet is complicated. However, this article will help you solve it out by comparing 10G SFP+ Fibre Channel transceiver modules and 10G Ethernet SFP+ modules.
Encoding Mechanisms of Ethernet and FC
Any time we’re transmitting or storing data, we encode it in some form or another. Then we need to understand the encoding mechanisms of Ethernet and FC.
1, 2, 4, and 8 Gb Fibre Channel all use 8b/10b encoding. Meaning, 8 bits of data gets encoded into 10 bits of transmitted information, the two bits are used for data integrity. For example, Original 1Gb FC is actually 1.0625Gb/s, and each generation has kept this standard and multiplied it. 8Gb FC would be 8×1.0625, or actual bandwidth of 8.5Gb/s. 8.5*.80 = 6.8. 6.8Gb of usable bandwidth on an 8Gb FC link.
10GE (and 10G FC, for that matter) uses 64b/66b encoding. For a 10Gb link using 64b/66b encoding, that leaves 96.96% of the bandwidth for user data, or 9.7Gb/s.
10G SFP+ Fibre Channel (FC) transceiver, as the name implies, is the 10G optical transceivers used for Fibre Channel applications. 10G FC SFP+ module has the same footprint as SFP form factor and is compliant with MSA SFF-8431. 10G SFP+ Fibre Channel transceivers uses the either the 850nm VCSEL as the transmitter fro multimode fiber or 1310nm/1550nm laser as the transmitters for single-mode fibers in SONET OC-192 /SDH, 10GBASE-SW, 10GBASE-LW, 10GBASE-EW, and 10GBASE-ZW applications.
10G SFP+ Fibre Channel Transceiver Module
Cisco DS-SFP-FC10G-LW, seen in the above image, is the long-range single-mode 10G SFP+ FC optical module for a link length of 10km over 1310nm wavelength. 10GFC is backward compatible with previous generation 8G/4G/2GFC and will auto-negotiate down to the fastest speed supported by both ports. This allows 10GFC devices and switches to be seamlessly integrated into expansion segments of existing FC networks without a forklift upgrade.
10GBASE SFP+ Ethernet Transceiver Module
SFP+ 10G modules is the optical transceiver for serial optical communication applications at 10Gbps. Unlike the SFP+ FC transceivers, 10GBASE SFP+ Ethernet modules can use either copper or fiber cabling. SFP+ 10GBASE-T optical transceiver supports Cat6 RJ45 copper cables for a link length of 30m. 10GBASE SFP+ Ethernet modules are available in several 10 Gigabit Ethernet standards like 10GBASE-SR Ethernet, 10GBASE-LR, 10GBASE-LRM, 10GBASE-ER, 10GBASE-ZR, and 10GBASE-T.
HPE 10G SFP+ module
Cisco SFP-10G-LR is the 10km Cisco 10GBASE-LR SFP+ module that uses 1310nm as the transmitter type over single-mode fiber cables. 10GBASE-LR SFP+ modules cannot be auto-negotiate with 1000BASE SFP transceivers, but for most switches, SFP+ ports can support 1G SFP modules for 1Gbps data rate.
Comparison Between 10G Fibre Channel SFP+ and 10G Ethernet SFP+
From the previous description, we can easily draw a conclusion that 10G Fiber Channel SFP+ and 10G Ethernet SFP+ share several specification in common.
Footprint
They have the same form factor as 1000BASE SFP transceiver modules.
Performance
Except the application, 10G Fiber Channel SFP+ SW module and 10Gb SR SFP+ transceivers have the very similar functions with each other. For the exact information, please see the following table.
Application
10G Fiber Channel SFP+ is used in 10G Fibre Channel, yet 10G Ethernet SFP+ is utilized in 10G Ethernet networks.
2017 Prediction of Ethernet and Fibre Channel
Without denying, Ethernet is the dominating network for every data center and server room. The “old” Ethernet network—1Gb/s and 10Gb/s speeds relied heavily on TCP to deliver data, which was reliable but somewhat unpredictable. However, today’s Ethernet runs at 25, 40, 50, or 100Gb/s speeds, is no longer dependent on TCP alone. It also supports RDMA connections which lower latency and frees up CPU cycles to run applications. 100Gb/s technology is quite matured in 2017 and there are many relevant devices available on the market, such as CFP/QSFP28 optical transceivers, 100G switches and network interface cards, 24 fiber MTP cables, etc.
Fibre Channel Vs. Gigabit Ethernet
Meanwhile, FC is still transitioning to 16/32 Gb/s technology (32Gb/s is not mature), which is quite slower than what Ethernet was supporting several years ago. For 32Gb/s FC network, it still supports only block storage traffic. Other storage (and other non-storage) traffic will require an Ethernet network anyway.
If we look at what is coming in 2017, the battle will not be 10/40/100GbE Vs. 8/10/16/32Gb FC. Almost everyone would agree that it would be nice to have a single network for all traffic, and very few users want a new protocol and the challenges of changing the way that they do things.
Conclusion
FC or Ethernet, which is best for storage? 10Gb FC SFP+ has the same usable bandwidth as the 10Gb Ethernet SFP+, and without the overhead of FCoE, but you don’t get the consolidation benefits of using the same physical link for your storage and traditional Ethernet traffic. Fiberland offers reliable 10G SFP+ transceivers in Ethernet, FC, BiDi, CWDM/DWDM applications. If you are interested in our products, please contact us directly.

What is XENPAK Transceiver ?

XENPAK is a multisource agreement (MSA) for a 10 Gigabit Ethernet (10GbE) transceiver package. It’s the oldest 10G fiber optic transceiver. XENPAK transceivers is designed with XAUI interface and Digital Diagnostic Monitor Interface, which comply with the XENPAK MSA protocol and satisfy the application of 802.3ae Ethernet protocol 10GB. XENPAK transceivers are supplied for physical layer interfaces supporting multi-mode and single mode fiber optic cables and InfiniBand copper cables with connectors like as CX4. Transmission distances vary from 100 metres (330 ft) to 80 kilometres (50 mi) on fiber and up to 15 metres (49 ft) on CX4 cable. Newer XENPAKs using the 10GBase-LX4 standard operated using multiple wavelengths on legacy multi-mode fibres at distances of up to 300 metres (980 ft), eliminating the need to reinstall cable in a building when upgrading certain 1 Gbit/s circuits to 10 Gbit/s.
The XENPAK form factor was initially supported by numerous network equipment manufacturers and transceiver optics vendors. However, advances in technology led to more compact form factors for 10 Gigabit Ethernet applications. Soon after the standard was introduced in 2001, two related standards emerged: XPAK and X2. These two standards have the same electrical interface as XENPAK (known as XAUI) but a smaller mechanical properties. XENPAK was replaced by X2 or SFP+ transceiver that providing higher port density and most of the transceiver vendors stop to provide to market. Nowadays,however,there is quite few ethernet switch or routers with Xenpak port worked, a Xenpak to SFP+ converters was produced to meet the needs.
Types of XENPAK
Classified by Applications: XENPAK CWDM,XENPAK DWDM,Dual fiber XENPAK, XENPAK BIDI
Classified by Distance: CX4 for 15m on copper, SR for 300m,LRM for 220m, LR for 10km or 20km, ER for 40km, ZR for 80k
