Cabling Guidelines
Cabling Guidelines
This section describes the cabling guidelines and port connections.
Ethernet Port Connections
For copper Ethernet ports, cable lengths from the switch to connected devices
must be within 328 feet (100 meters).
Use either straight-through or crossover Category 5 cables with RJ-45 connectors
to connect from the switch Ethernet ports to other devices.
Use Category 5 cables for 100BASE-TX and 1000BASE-T traffic. Use
Category 3 or Category 4 cables for 10BASE-T traffic.
SFP Module Port Connections
For the SFP module port connections, Table A-2 lists the cable specifications.
Each port must match the wave-length specifications on the other end of the cable,
and for reliable communications, the cable must not exceed the stipulated cable
length.

6. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX SFP modules, and a
short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX SFP
module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and
the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link
distances greater than 984 feet (300 m).

For SMF connections, use one of the LCs listed in Table A-3 or Table A-4. For
MMF connections, use one of the LCs listed in Table A-5. Use the Cisco part
numbers to order the patchcords that you need, or order patchcords from your
vendor.
