GBIC Transceivers 63GBIC Transceivers The Gigabit Interface Converter (GBIC) slot on a Gigabit Ethernet Interface Module(Model Number 3C16826 and 3C16843) requires that you attach a GBICtransceiver to it prior to attaching fiber-optic cabling (see Figure 22).One side of the transceiver fits into the GBIC slot and the other side offers anetwork port. The transceivers currently supported by this Switch use fiber-opticduplex subscriber connectors (SC).Figure 22 GBIC Fiber-Optic TransceiverCompatible Transceivers The following transceivers are compatible with the Switch 4005 GBIC InterfaceModules: 1000BASE-LX GBIC Transceiver (Model Number 3CGBIC92) 70-km Long Haul GBIC Transceiver (Model Number 3CGBIC97)The Switch 4005 GBIC Interface Module complies with all applicable GBICstandards. GBIC transceivers from other vendors that comply with these standardsshould function properly when attached to the module. However, 3Com has onlytested the 1000BASE-LX GBIC Transceiver (Model Number 3CGBIC92) and the70-km Long Haul GBIC Transceiver (Model Number 3CGBIC97).1000BASE-LX GBICTransceiverThe 1000BASE-LX GBIC transceiver (Model Number 3CGBIC92) supports a directconnection to single-mode fiber-optic cable, or connection to multimode fiberthrough a conditioned launch cable. Table 14 lists the transmission ranges for eachGBIC 1000BASE-LX connection.To ensure optimal performance, compatibility, and regulatory compliance, use onlyconditioned launch cables that 3Com supports.
