XLoom Communications Inc. has started to sample the iFlame optical chip, a multi-channel, high-density, cost-effective, optical engine for grid computing and datacenter applications.

According to XLoom, iFlame is the industry's first chip-scale four-channel optical transceiver, which is aimed at data center applications running over InfiniBand, Ethernet and Fiber-Channel. iFlame is designed to replace bulky copper interconnects for higher data rates up to 20Gbps per link with easy-to-install fibers.

The iFlame chip, implemented as an optical engine, enables high-speed, high-density, cost-effective interconnect applications such as Opto-electrical media converters, optical active connectors and cables as well as traditional transceivers such as the upcoming QSFP form factor.

The iFlame, which is less than 1cm? in size, features an array of four 850nm VCSELs (Vertical-Cavity Surface-Emitting Lasers) and four photodiodes for data rates of 1.25Gbps to 5Gbps per channel, for a total aggregate of up to 20Gbps.
