Uplink Ports
Three types of XENPAK and X2 transceivers have cabling guidelines. The transceivers types and their
guidelines are listed in
Table B-6.
Supervisor Engine 720 3 • Two 1000BASE-X ports (The two ports
require SFP transceivers)
• One 10/100/1000 RJ-45 port (The port does
not require a pluggable transceiver)
Note Only two uplink ports can be used at one
time.
Supervisor Engine 720-10GE 5 • Two 10-GBASE-X ports (The ports require
X2 transceivers)
• Two 1000BASE-X ports (The ports require
SFP transceivers)
• One 10/100/1000 RJ-45 port (The port does
not require a pluggable transceiver)
Supervisor Engine 2T 5 • Three 1000BASE-X ports (The ports require
SFP transceivers)
• Two 10-GBASE-X ports (The ports require
X2 transceivers)

LX4
(XENPAK-10GB-LX4 and
X2-10GB-LX4)
The Cisco LX4 transceiver supports link lengths of 300 meters on
standard FDDI grade MMF. To ensure that specifications are met, the
transmitter output should be coupled through a mode conditioning patch
cord. Cisco offers two mode conditioning patch cords:
• CAB-GELX-625=—Mode-conditioning patch cable supporting
62.5
micron fiber with dual SC connectors.
• CAB-MCP50-SC=—Mode-conditioning patch cable supporting
50
micron fiber with dual SC connectors.
