General Description
Currently, the following GBICs are certified for use:
Short-wavelength fiber optic GBICs 100-M5-SL-I or 100-M6-SL-I with
Open Fiber Control (OFC) support connection to legacy 1062 megabaud
Fibre Channel networks. The Optical Link Modules (OLMs) used by many
legacy Fibre Channel transmitters and receivers contain an internal OFC
system. The OFC is a safety interlock that detects when the optical link has
been interrupted and shuts down the laser. Each of the two transmitters in
the Fibre Channel link will try periodically to reestablish the link. The laser
pulse duration for this re-connect operation is very short. Newer designs of
fiber optic transmitters with lower launch powers (like those used in
GBICs) do not generally use OFC. However, if one end of a Fibre Channel
link has OFC, then both ends must have it.
Short-wavelength fiber optic GBICs 100-M5-SN-I or 100-M6-SN-I without
OFC to support connection to new non-OFC Fibre Channel components.
Long-wavelength fiber optic GBICs 100-SM-LC-L.
Copper Inter-Enclosure GBIC (Active) 100-TW-EL-S or 100-TP-EL-S with
either DB-9 or HSSDC connectors.
Copper Intra-Enclosure GBIC (Passive) 100-TW-EL-S or 100-TP-EL-S
with either DB-9 or HSSDC connectors.
Certified GBICs may be populated in any combination that suits your use. They
are “hot-pluggable” and you may snap them in/out without tools.
Refer to the Reference Information appendix for certified GBICs and their
specifications. Refer also to the Removal Replacement section of this manual for
more information. Figure 1-3 shows a typical GBIC. This one supports fiber optic
interconnection media.
