SEI launches 8Gb/s SFP+ transceivers for Fiber Channel

Sumitomo Electric Industries Ltd (SEI) of Tokyo, Japan says it is now shipping 8Gb/s SFP+ optical transceivers for Fiber Channel (FC) applications.

SFP+ is the next-generation transceiver package for 8Gb/s Fiber Channel applications at 850nm and 1310nm, and SEI is an active member of the SFF-8431 committee (responsible for standardizing SFP+ transceivers).

“One of the latest significant events to impact the FC market is the availability of next-generation products capable of supporting 8Gb/s speeds,” says Ichiro Kono, general manager of SEI’s Optical Transmission Components division. “The migration from 2Gb/s to 4Gb/s has already materialized throughout the SAN [storage-area network]. As 4Gb/s transmission speed expands to HBAs [host bus adapters], switches will require 8Gb/s bandwidth,” he adds.

“The 8Gb/s SFP+ module further expands our product portfolio, providing system designers with flexible options in building out their networks,” says Kono. SEI is launching three transceivers in the SPP5100/5101 series:

  • SPP5100/5101SX for FC-PI-4 using an 850nm vertical-cavity surface-emitting laser (VCSEL) for operation over multi-mode fiber (MMF) at distances of up to 150m;
  • SPP5100/5101MX for FC-PI-4 using a 1310nm Fabry-Perot laser for operation over single-mode fiber (SMF) at distances of up to 1.4km;
  • SPP5100/5101LX for FC-PI-4 using a 1310nm distributed feedback (DFB) laser for operation over single-mode fiber at distances of up to 10km.

SEI’s subsidiary ExceLight Communications Inc of Durham, NC , USA will exhibit the SPP5100/5101 series at the collocated Optical Fiber Communication Conference and Exposition (OFC) and National Fiber Optic Engineers Conference (NFOEC) in San Diego, CA, USA (26-28 February).
