GBIC Transceivers

Compatible Transceivers

1000BASE-LX GBIC
Transceiver
The Gigabit Interface Converter (GBIC) slot on a Gigabit Ethernet Interface Module
(Model Number 3C16826 and 3C16843) requires that you attach a GBIC
transceiver 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 a
network port. The transceivers currently supported by this Switch use fiber-optic
duplex subscriber connectors (SC).

The Switch 4005 GBIC Interface Module complies with all applicable GBIC
standards. GBIC transceivers from other vendors that comply with these standards
should function properly when attached to the module. However, 3Com has only
tested the 1000BASE-LX GBIC Transceiver (Model Number 3CGBIC92) and the
70-km Long Haul GBIC Transceiver (Model Number 3CGBIC97).
The 1000BASE-LX GBIC transceiver (Model Number 3CGBIC92) supports a direct
connection to single-mode fiber-optic cable, or connection to multimode fiber
through a conditioned launch cable. Table 14 lists the transmission ranges for each
GBIC 1000BASE-LX connection.

To ensure optimal performance, compatibility, and regulatory compliance, use only
conditioned launch cables that 3Com supports. See the 3Com Web Page; start by
