MACOM and Sumitomo Electric to Showcase 100G PAM-4 over Single Wavelength

Sumitomo Electric Industries, Ltd.

MACOM Technology Solutions Inc. (MACOM) and Sumitomo Electric Industries, Ltd. will conduct a joint 100 Gbps PAM-4 single wavelength (lambda) demonstration at OFC 2017, March 21 - 23 at the Los Angeles Convention Center, Los Angeles, CA, USA.

The solution features MACOM's 100 Gbps, 16nm FinFET, PAM-4 PHY, linear driver and high bandwidth, low noise transimpedance amplifier (TIA), and Sumitomo Electric's high bandwidth Electro-Absorption Modulated Laser (EML) to drive a 53Gbaud PAM-4 modulated signal over single mode fiber.

It is anticipated that the combination of these technologies will pave the way for serial 100Gbps and 400Gbps transmission to enable the lower cost and higher port density optical modules required by data center operators and access networks. The industry is moving quickly to implement 100G interconnects to accommodate the massive growth of IP traffic. Single wavelength 100Gbps is transforming the industry and will enable deployment of the lowest cost 100Gbps QSFP28 and 400Gbps QSFP-DD and OSFP modules quickly.

PAM-4, adopted by the IEEE, is expected to be the most cost-effective and efficient enabler of 100G and 400G in the data center. In a 100G application, not only does the technology reduce the number of lasers to one, it eliminates optical multiplexing, and allows single lambda 100G optical modules to work in existing switch and server line cards with QSFP cages. PAM-4 makes more efficient use of electronic and optical components by packing two bits for every symbol sent over the fiber. Single-lambda 100G PAM-4 offers the simplest architecture, lowest component count, the most streamlined data path, higher reliability and an easy upgrade path to 400G Ethernet and beyond.

"2017 has been an exciting year for MACOM and our collaboration with Sumitomo Electric only adds to that. This demonstration marks the onset of a new generation of 100G and 400G modules, and highlights the significant value that single lambda technology brings to hyper scale data centers in terms of density, reliability and economics," said Omar Hassen, Vice President, Connectivity, at MACOM. "MACOM is uniquely positioned with a complete set of components to supply the PAM-4 100G and 400G markets on the verge of explosive growth."

This live demonstration will be held at OFC 2017 in MACOM's booth 1736 and in Sumitomo Electric's booth 2703.
