Chris Cole, Chair of CW-WDM MSA, explains why standardising O-band, datacoms, laser sources is critical to the future of AI and machine learning.

In his article for “Gazettabyte”, Chris Cole, Chair of CW-WDM MSA, pictured, explains why CST Global has joined an elite group of companies to specify laser sources and the wavelength grids they use. The lasers in question operate in the O-band (1260nm-1360nm) used for datacom optics.

“Artificial intelligence (AI) and machine learning have become an integral part of the businesses of the webscale players. The mega data centre players apply machine learning to the treasure trove of data collected from users to improve services and target advertising. They can also use their data centres to offer cloud-based AI services.

“Training neural networks with data sets is so intensive that it is driving new processor and networking requirements. It is also impacting optics. Optical interfaces will need to become faster to cope with the amount of data, and that means interfaces with more parallel channels.

“The CW-WDM MSA is defining eight, 16 and 32 channels and will build on work done by the ITU-T and the IEEE. This is good news for the laser manufacturers given they have already shipped millions of lasers for datacom.”
