Cabling 1000BASE GBIC Ports
Each 1000BASE GBIC (Gigabit Interface Converter)
port accepts one of these transceivers:
■
1000BASE-SX GBIC
— Use this transceiver to
connect the GBIC port directly to multimode
fiber-optic cable. For instructions, see the
procedure in this section.
■
1000BASE-LX GBIC
— Use this transceiver to
connect the GBIC port directly to single-mode
fiber-optic cable or to multimode fiber using a
conditioned launch cable. For instructions on using
this transceiver to connect to single-mode fiber,
see the procedure in this section. To connect this
transceiver to multimode fiber, see “Connecting
the LX Transceiver to MMF” on page 24 for details.
To ensure optimal compatibility, performance, and
regulatory compliance, use only GBIC transceivers and
conditioned launch cables that 3Com supports. For a
list of currently supported GBICs and launch cables,
visit this 3Com Web site:
You can insert and remove the GBIC transceiver while
the system is powered on and running.
To connect a GBIC port directly to single-mode fiber
with an LX transceiver, or to connect a GBIC port
directly to multimode fiber with an SX transceiver,
follow these steps:
1
Read and follow the “Fiber Safety Precautions” on
page 19 and the Caution at the beginning of
“Cabling Gigabit Ethernet Ports” earlier in this
chapter.
2
Orient the transceiver so that the duplex SC
connector is toward you, as shown in Figure 6.
