Lumentum, Innovium achieve 400G FR4 transceiver, TERALYNX Switch ASIC interoperability

Lumentum Holdings and switch chip maker Innovium, say they have established interoperability between Lumentum’s 400G QSFP-DD FR4 optical transceivers and Innovium’s 12.8-Tbps TERALYNX Switch ASIC. The Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi-Source Agreement (MSA) specifications describe an optical transceiver form factor for 200-Gbps and 400-Gbps applications, particularly 400 Gigabit Ethernet. Demonstrations of QSFP-DD optical modules have been highlights of both OFC and ECOC this year.

Successful 12.8-Tbps TERALYNX interoperability testing builds on Lumentum’s OFC 2018 demonstration of 2-km optical fiber data traffic flow through a QSFP-DD FR4 optical module,” said Justin Abbott, senior product line manager at Lumentum. “Lumentum is poised to deliver MSA-compliant, fully tested, high-performance solutions as the industry prepares for the 400G transition.”

TERALYNX, meanwhile, features line-rate programmability, large on-chip buffers, advanced telemetry, and low-latency, says Innovium. The switch chip supports 10GbE to 400GbE and provides 128 ports of 100GbE, 64 ports of 200GbE, or 32 ports of 400GbE in a single device.

Deployments of 5G, video, NVMe over fabric, machine learning, and data analytics are driving cloud and telco customers to scale their network infrastructure and embrace 400G connectivity,” said Amit Sanyal,” vice president of product management and marketing at Innovium. “The industry provider of low-latency, programmable 12.8-Tbps switch silicon is excited to announce the interoperability of TERALYNX switch with Lumentum’s 400G QSFP-DD FR4 transceiver. Solutions with proven interoperability will deliver a highly scalable network with compelling economic value.”
