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.
