Finisar Demonstrates New Optical Modules And Wavelength Selective Switch At OFC 2017

Finisar announces multiple optics product and technology demonstrations are to be held during OFC between 19-23 March 2017 at
the LA Convention Center. The company will feature new module types, including 400G CFP8 FR8 and LR8 transceivers, 200G QSFP56
FR4 and LR4 transceivers, and a 100G QSFP28 eSR4 extended reach transceiver. The company will also demonstrate its new Flexgrid®
single low profile Wavelength Selective Switch (WSS) for next generation ROADM subsystems. 

During OFC, the company will have multiple demonstrations of its MSA-compliant 400G CFP8 transceiver, which is enabled by 50G pulse
amplitude modulation (PAM) technology. PAM4 is a modulation format that has been adopted by the IEEE for 50 Gb/s per lane Ethernet
signaling and is expected to become the building block for future 50GE, 100GE, 200GE and 400GE interconnects. The Finisar CFP8
family includes an FR8 version supporting 2km reaches and an LR8 version for 10km reaches, both operating over single mode fibre.
The module is designed for router-to-router and router-to-transport client interfaces.

The single low profile WSS, designed for single-slot ROADM line cards, is the newest addition to the portfolio of Wavelength Selective
Switches built on Finisar's Flexgrid® and LCoS technology. Fully ITU Flexible Grid compliant, it offers deployment of bandwidth at 6.25
GHz spectral width and intra-channel attenuation control designed to enable optimal performance over an optical transmission link. It comes
in a wide range of configurations from 1x2 to 1x9, to support next generation express and colourless directionless add/drop architectures.

The live demonstrations at OFC will show two Finisar 100G QSFP28 eSR4 transceivers connected over 300 metres of OM3 fibre. Traffic will be
generated and measured by an Anritsu MT1100A Network Master Flex. The live demonstration will also feature a 1x9 WSS configured to switch
a mix of transceiver and ASE inputs to a common output port.

"Once again, Finisar is pleased to demonstrate industry break-through and market-leading products to our customers at the largest show
focused on Optical Communications," said Todd Swanson, EVP of Global Sales & Marketing at Finisar. "As the industry leader in optics, we
remain focused on delivering critical and innovative optics technologies needed to support our customers."

    With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

    1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

    AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

    Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
