an interesting abstract though (following Anadigics acquisition by Gaas Labs) :

Macom and Kaiam

M/A-COM Technology Solutions (Macom), a developer of high-performance analog RF, microwave and optical semiconductor products, announced that it will be collaborating with Kaiam Corp. to showcase an industry leading 400G demonstration at OFC. Macom is consolidating the high-speed semiconductor content in 100G/400G transceivers, optimizing its chips to enable highly-differentiated performance, power, size and cost benefits.

Macom’s MAOM-002304 Quad Directly Modulated Laser Driver and M37049 Quad CDR, were featured in Kaiam’s 400G over single-mode fiber demonstration, showcasing a breadth of Macom’s optical and photonic content enabling next generation optical networking applications.

Ray Moroney, product manager at Macom, commented, “These ICs have the lowest power in their class, which is critical for a 400Gbs multi-channel solution. Kaiam’s module is compatible with a CDFP connector and provides 50% higher density per 100G than QSFP28. This joint development shows MACOM’s ability to support 400G applications.”
