HGLM-1063

Fibre Channel GBaud Optical Link Module Technical Data HGLM-1063 Features ANSI X3.230-1994 Fibre Channel Standard Compatible (FC-0) FCSI-301-Rev 1.0 “GBaud Link Module Specification” Compatible Standard 20 Bit (1063 MBd), TTL Interface Class I Laser Safety Certified Single +5.0 V Power Supply Optical Link Module” specification. The HGLM-1063 transmits and receives 8b/10b encoded, parallel, data in the 20 bit wide format defined by the FCSI-301 document. The 20 bit wide data is transmitted at 100MB/sec over a serial fiber link and has the capability to receive data at 100 MB/sec simultaneously. With overhead, this translates to a serial line rate of 1062.5 MBaud transmitting and 1062.5 MBaud receiving. The serial data link uses a 780 nm laser transmitter and photodiode. The optimum fiber is 50/125 µm multimode fiber (62.5/125 µm multimode fiber can be used with degraded performance) and attaches to the HGLM-1063 via a duplex SC connector. As specified in the Fibre Channel Standard, the HGLM-1063 is a Class 1 laser safe device; the transmitted optical signal shuts down in the case of an open fiber condition after a specific time interval. The HGLM-1063 accomplishes this by monitoring the transmitted optical power levels, and the received optical signal.
