CW-WDM MSA

Photonics helps create industry standard


 

Sivers Photonics is a founding member of an elite group of companies signed up to a multi-source agreement (MSA) to define a new, industry-standard for continuous wave (CW) laser sources. 

 

 

The CW-WDM MSA (Continuous-Wave Wavelength Division Multiplexing Multi-Source Agreement) was formed to standardise WDM CW sources in O-band for emerging advanced Silicon Photonics (SiPh) based optics applications that are expected to move to 8, 16, and 32 wavelengths, to support high data rate advanced optical communication and computing applications.

CW lasers are critical to the integrated photonics devices used in next-generation artificial intelligence and data-centre applications and Sivers Photonics is helping to spearhead the standardisation, along with industry leaders and household names, Arista, Ayar Labs, imec, lntel, Lumentum, Luminous Computing, Quintessent, Sumitomo Electric, Il-VI and MACOM.

The goal of the MSA is to generate a set of specifications for optical power sources. Once the standard is completed, vendors can leverage a robust supply chain and suppliers have a unified, large market to sell into. This will allow developers and suppliers to leverage their strategic investments in the current generation of optical products to accelerate time to market of next generation products.

Today’s high volume datacom optics defined by IEEE and ITU standards specify serial or four WDM interfaces. These standards specify single and four wavelengths for today’s datacom optics. The CW-WDM MSA is different from optical communication standards groups in that it solely focuses on specifying the laser source instead of the full communications link and is not targeted at any specific application.

lncreasing the number of wavelengths, while staying in the O-band and aligning with ITU and IEEE standards, is a crucial part of the emerging ecosystem and will enable improvements in performance, efficiency, cost, and bandwidth scaling. Such higher wavelength counts are needed for emerging applications such as silicon photonics (SiPh) based high-density co-packaged optics, optical computing, and Al, and enable a leap in performance, efficiency, cost, and bandwidth scaling compared with previous technology generations.

The specification will be made available throughout the photonics industry, allowing the development of compatible products from multiple vendors, and is seen as a decisive step to enhance market growth, improve customer choice, and encourage competition.
