Super Flat-top Athermal AWG DWDM MUX/DMX for 400G Data Transport

LOS ANGELES, June 6, 2017 /PRNewswire/ -- Terraphotonics Systems Corporation—a leading provider of DWDM optical mux/demultiplexer in North America—today announced the release of 40-channel C-band DWDM optical mux/demultiplexer (MUX/DMX) 1RU chassis product, which is designed for supporting 400G data transport. 

The super flat-top DWDM MUX/DMX product is made up of ultra wideband Athermal AWGs (AAWGs) that could be used for 400G data transmission.  The data transmission capacity at 400G is necessary technology solution in ever-increasing data traffic trend in the up-and-coming 5G world.  The LTE and LTE-A telecommunication periods are best served by 10G SFP+, 40G CFP ~CFP4, and 100G CFP8 transceivers; however, 400G data transmission capability envisioned by high-performance data centers is becoming the market reality on the horizon. 

After seven years of 100G Ethernet standard, the IEEE launched P802.3bs 400GbE task force in March 2014 to increase data transport capability required to handle soaring data traffic volume driven by proliferation of video streaming (e.g., popularity of Netflix), social media-based image app usages (e.g., Facebook), super-scale data centers (e.g., Google Data Center), mobile phones, cloud computing, and 5G carriers.  This task force has planned to complete its standard by December 2017.

Terraphotonics has been marketing standard and customized optical MUX/DMX to its American customers. Forming strategic partnerships with DWDM MUX/DMX athermal AWG component specialty companies, especially companies possessing their own athermalization IP or patent, Terraphotonics has successfully sold market-proven athermal AWG products of various diversity and capacity on an integrated supply chain management (SCM) and OEM CM contract.

Presently, Terraphotonics manufactures and markets globally all custom types of AAWGs in multiple channels (e.g., 40CH/44CH48CH/80CH/88CH/96CH), spectrum (e.g., Gaussian/Semi-flat/Flat-top), channel spacing (200GHz/100GHz/50GHz), band (C-band/L-band/dual-C/L-cyclic bands), optional features (e.g., internal or external monitoring TAP port, OSC port, etc.), package configuration (in brick or in chassis), and unique (e.g., comb filters) or special customized requirements (e.g., 1/2 MUX and 1/2DeMUX in one AWG housing).

"As a niche vendor, we have been following the trend in DWDM system requirements from 100GHz C-band 40 channels to shorter bandwidths with more channels.  For 100G data transport whether it is serviced by 10 by 10G or 4 by 25G laser optics, Terraphotonics's standard or regular AAWGs can provide the data network providers with necessary DWDM optical muxing and demuxing function, but for 400G data transport, the regular flat-top is not good enough, requiring more flattening of the filtering band," says Dr. Donald Yu, the CMO of Terraphotonics. Yu adds that this type of wide-band AAWG or Ultra wide-band AAWG has not been available commercially.

"The release of this 400G-capable DWDM MUX/DMX product is made possible by our  partner whose R&D program tuned their  super athermal AAWG production technology for manufacturing ultra-wide super flat-top 400G-capable AAWGs," says Adib Sharif, the Vice President of SCM and International Operations at Terraphotonics.  Sharif adds that the key issue in making the 400G super flat-top AAWG is to widen band at 90 GHz at 3dB (644pm~728pm) while controlling insertion loss (IL) at minimum.
