Continuous-Wave Wavelength Division Multiplexing MSA gets underway

A new Continuous-Wave Wavelength Division Multiplexing Multi-Source Agreement (CW-WDM MSA) consortium has been established to define and promote specifications for multi-wavelength advanced integrated optics.

The CW-WDM MSA said it will solely focus 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.

Currently, IEEE and MSA standards specify four WDM interfaces. 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.

Promoter Members of the CW-WDM MSA are Arista Networks, Ayar Labs, CST Global, imec, Intel, Lumentum, Luminous Computing, MACOM, Quintessent, Sumitomo Electric, and II-VI.

In addition, several Observer Members have signed on to be briefed on the development of the standard to enable early technology development based on the new specifications. Observer Members are AMF, Axalume, Broadcom, Coherent Solutions, Furukawa Electric, GlobalFoundries, Keysight Technologies, NeoPhotonics, NVIDIA, Samtec, Scintil Photonics, and Tektronix.

“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.”

“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.”

CWDM8 MSA targets 400G data centre links at 2 km and 10 km

Leading vendors, including Accton, Barefoot Networks, Credo Semiconductor, Hisense, Innovium, Intel, MACOM, Mellanox, Neophotonics, and Rockley Photonics, have formed a new CWDM8 MSA (8-wavelength Coarse Wavelength Division Multiplexing Multi-Source Agreement) Group dedicated to defining optical specifications and promoting adoption of interoperable 2 km and 10 km 400 Gb/s interfaces over duplex single-mode fiber.

The goal is to develop optical link specifications that will enable cost-effective, low power consumption 400G duplex single-mode optics using 50G per wavelength optical NRZ modulation, all while maintaining full compatibility with standard 50G PAM4 electrical interfaces.

The group is targetting next-generation module form factors such as QSFP-DD, OSFP, and COBO, to handle the 400 Gb/s interface at distances of 2 km and 10km for intra data centre of campus data centre connectivity.

"There is currently no adequate solution in the market to meet our needs for cost effective and uncooled 400G optical interfaces for 2km and 10km reaches. We welcome the formation of the CWDM8 MSA, which offers proven 50G NRZ technology to enable compact and low power dissipation form factors for 400G," stated Yu Li, VP of Data Center Switching, Huawei.

#OFC2016: AT&T Pushes for Open ROADM MSA

An Open ROADM project is underway with the backing of AT&T and a goal of driving faster innovation and open software control for the Reconfigurable Optical Add/Drop Multiplexers (ROADMs) used in optical transport networks.

The Open ROADM Multi-Source Agreement (MSA) defines interoperability specifications for Reconfigurable Optical Add/Drop Multiplexers (ROADM). Included are the ROADM switch as well as transponders and pluggable optics. Specifications consist of both Optical interoperability as well as YANG data models.

Participants in the MSA include AT&T, Ciena, Fujitsu, and Alcatel-Lucent USA (Nokia).

Molex and Cisco Target Double-Density QSFP Interfaces

Molex and Cisco announced their participation in a multi-supplier agreement (MSA) to create high-speed, double-density quad small form factor pluggable (QSFP-DD), a new high-speed interface. Thirteen industry leaders have joined the MSA to collaborate in developing this new high-speed interface.

The new QSFP-DD interface expands on widely adopted QSFP enabling systems to support backwards compatibility to existing 40 GbE and 100 GbE QSFP interfaces as well as a clear path to future 2x100 GbE and 400 GbE interfaces. By maintaining the same port density per rack unit, customers can speed up networks without redesigning the architecture.

“With a clear trend towards hyper-converged fabrics, customers need an aligned switch silicon and optics roadmap,” said Luca Cafiero, senior vice president and general manager at Cisco. “Global IP traffic is expected to reach 1.4 zettabytes next year, reflecting a CAGR from 2012 to 2017 of 23 percent. All players involved in network architecture will have to step up their game to meet this demand, and the MSA for QSFP DD is a big step in that direction. We are confident that, with industry leaders like Molex, we can help to lead the development of high-speed technology that will be broadly used throughout the industry.”
