Fulcrum and Luxtera to Demo 40 Gbps Datacenter Ethernet Switch

Fulcrum Microsystems and Luxtera have developed a low-latency, 40-Gigabit Ethernet switch/router reference design for datacenter backbone applications. The reference design is composed of a card developed by Luxtera using its nanophotonic "Blazar" 40-Gigabit optical active cable that fits into the Fulcrum "Reno" low-latency, 10-Gigabit Ethernet router platform for datacenter applications.

Luxtera's Blazar is a 40-Gigabit optical active cable (OAC) that leverages the company's CMOS photonics technology. Blazar binds four 10-Gigabit Ethernet channels into one 40 Gbps high-density QSFP connector and has a reach of up to 300 meters.

Fulcrum's "Reno" reference design is a 1RU switch/router system that uses Fulcrum's FocalPoint low-latency switch, or Fulcrum's low-latency router to offer 24 full-rate 10 Gigabit Ethernet ports. With the Luxtera mezzanine card, Reno is configured to feature three 40 Gbps QSFP ports and 12 CX4 10-Gigabit Ethernet ports, all running at full line rate with less than 300 nanoseconds of latency for L3 routing.
