M/A-COM has announced it will collaborate with Kaiam to showcase a 400G demonstration at the Optical Fibre Conference (OFC) in Los Angeles, 24^th to 26^th March 2015. MACOM is consolidating the high speed semiconductor content in 100G/400G transceivers, optimising chips to provide differentiated performance, power, size and cost benefits.

MACOM’s MAOM-002304 Quad Directly Modulated Laser (DML) Driver and M37049 Quad CDR, will be featured in Kaiam’s 400G over single-mode fibre demonstration, showcasing a breadth of MACOM’s optical and photonic content, enabling next-gen optical networking applications. According to MACOM, these ICs boast the lowest power in their class, which is critical for a 400Gb/s multi-channel solution.

Kaiam’s module is compatible with a CDFP connector and provides 50% higher density per 100G than QSFP28. While 16x25G is the IEEE standard proposal for multimode 400G, this is the industry’s first demonstration of a single-mode 16x25G solution. The module is enabled by Kaiam’s unique laser packaging technology that has been deployed for 40G and 100G. The approach is aimed at leading edge 100G and 400G applications that can’t wait for 50G electrical interfaces.

“This joint demonstration showcases MACOM’s ability to service 400G applications today,” said Ray Moroney, Product Manager, MACOM. “With our roadmap commitment to lower power, lower cost, high performing ICs, we believe we are positioned excellently to enable the industry’s transition to 400G applications.”

“Optical links are growing in every dimension available, both to higher baud-rate and more lanes,” said Karen Liu, Vice President of Marketing, Kaiam. “Kaiam’s MEMS-based packaging is used in high-volume 4-channel products today. This demonstration should alleviate any concerns the industry may have about moving to higher channel counts at 400G and beyond.”
