Installing Supervisor Engines

Attaching the Network Interface Cables

When an unconditioned laser source designed for operation on single-mode optical fiber is directly

coupled to a multimode optical fiber cable, an effect known as

differential mode delay

(DMD) might

result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver)

that can be supported reliably. The effect of DMD can be overcome by conditioning the launch

characteristics of a laser source. A practical means of performing this conditioning is to use a device

called a mode-conditioning patch cord.

XENPAK LRM

(XENPAK-10GB-LRM=)

The Cisco XENPAK-10GB-LRM transceiver supports link lengths of

722 feet (220 m) on standard Fiber Distributed Data Interface (FDDI)

grade multimode fiber (MMF). To ensure that specifications are met

over FDDI-grade, OM1 and OM2 fibers, the transmitter should be

coupled through a mode conditioning patch cord. Cisco offers two

mode conditioning patch cords: CAB-GELX-625= (mode conditioning

patch cable 62.5 microns, dual SC connectors) and CAB-MCP50-SC=

(mode conditioning patch cable 50 microns, dual SC connectors). No

mode conditioning patch cord is required for applications over OM3

fiber.

X2 LRM

(X2-10GB-LRM)

The Cisco X2-10GB-LRM transceiver supports link lengths of

220 meters on standard Fiber Distributed Data Interface (FDDI) grade

multimode fiber (MMF). To ensure that specifications are met over

FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled

through a mode conditioning patch cord. Cisco offers two mode

conditioning patch cords: CAB-GELX-625= (mode conditioning patch

cable 62.5 microns, dual SC connectors) and CAB-MCP50-SC= (mode

conditioning patch cable 50 microns, dual SC connectors). No mode

conditioning patch cord is required for applications over OM3.

X2 LX4

(X2-10GB-LX4)

The Cisco X2-10GB-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

62.5 microns, dual SC connectors) and CAB-MCP50-SC= (mode

conditioning patch cable 50 microns, dual SC connectors).
