CST Global receives £318,039 as part of SUPER8 project to develop 200Gbps, 8-channel CWDM transceivers
III-V optoelectronic foundry Compound Semiconductor Technologies Global Ltd (CST Global) of Hamilton International Technology Park, Blantyre, near Glasgow, Scotland, UK (a subsidiary of Sweden’s Sivers IMA Holdings AB) says that it is receiving £318,039 as a consortium member of the £1.1m Innovate UK government-funded SUPER8 research project, which aims to develop a scalable 200Gbps super-thermal, 8-channel CWDM (coarse wavelength division multiplexing) architecture. This will be applied to an ultra-high-speed, industry-standard transceiver platform for use in the optical data communications of hyper-scale cloud data centers.
The SUPER8 project consortium partners include CST Global, the Compound Semiconductor Centre (CSC) - a joint venture between Cardiff University and epiwafer foundry and substrate maker IQE plc of Cardiff, Wales, UK - and photonic integrated circuit (PIC)-vased transceiver manufacturer Kaiam of Newark, CA, USA (which has a primary manufacturing plant in Livingston, Scotland, UK).
“Cloud services, video-on-demand and the Internet of Things are increasing data bandwidth demand in global communications networks,” says CST Global’s technical director Andrew McKee. “This is driving the need for higher-capacity networks with greater transmission rates and a lower cost base,” he adds.
“CWDM architecture is the solution. It allows the bandwidths of existing optical networks to be increased by improving optical filtering to increase the quantity of wavelengths transmitted in a single fiber,” McKee continues. Low-cost, uncooled ridge-waveguide DFB lasers are used for the optical transmission, which the consortium of CST Global, CSC and Kaiam will model, build, test and optimize. The lasers are supplied as known-good-die-on-tape (KGDOT) to Kaiam for packaging, characterization and qualification.
“The lasers in the CWDM architecture offer reduced power consumption and increased reliability over existing DWDM architecture solutions,” McKee concludes.
