CW-WDM MSA Group Forms to Drive New Industry Standard for Optical Laser Sources
The CW-WDM MSA (Continuous-Wave Wavelength Division Multiplexing Multi-Source (News - Alert) Agreement) Group today announced its formation as an industry consortium dedicated to defining and promoting specifications for multi-wavelength advanced integrated optics.
IEEE (News - Alert) and MSA standards specify four WDM interfaces for today's high volume datacom optics. Emerging advanced integrated optics applications, such as silicon photonics (SiPh) based high-density co-packaged optics, optical computing, and AI, are expected to move to 8, 16, and 32 wavelengths. Standardizing higher wavelength counts is a crucial part of an emerging ecosystem which is enabling a leap in efficiency, cost, and bandwidth scaling compared to current technology. Increasing the number of wavelengths, while staying in the O-band and aligning with ITU and IEEE standards, allows developers and suppliers to leverage their strategic investments in the current generation of optical products to accelerate time to market of next generation products.
"We support and encourage consortiums like the CW-WDM MSA Group in order to accelerate important technical innovations," said Christopher Berner, Head of Compute at OpenAI. "OpenAI must be on the cutting edge of AI capabilities and low latency, high bandwidth optical interconnect is a central piece of our compute strategy to achieve our mission of delivering artificial intelligence technology that benefits all of humanity."
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. Such an approach allows developers to fully optimize optics to their customers' requirements without interoperability constraints while simultaneously creating a large business opportunity for laser source suppliers.
"Laser sources have been the critical building block of fiber optic communications, and standardizing their specifications has been key to the success of telecom and datacom optics," said Chris Cole, Chair of the CW-WDM MSA. "ITU-T established complete baselines for DWDM and CWDM grids. The IEEE then specified subsets of these grids for high volume data center applications, starting with 40G and 100G Ethernet optics. The CW-WDM MSA will similarly leverage ITU-T and IEEE standards to specify 8, 16 and 32 wavelength grids in O-band for emerging advanced datacom and computing optics. With the definition of multiple grid sets, the MSA will enable developers to choose what is optimum for their application, while allowing laser suppliers to only have to invest in one technology platform."News - Alert), NVIDIA, Samtec, Scintil Photonics, and Tektronix.
