XENPAK LRM

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

(XENPAK-10GB-LRM=)

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

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

(X2-10GB-LRM)

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

The Cisco X2-10GB-LX4 transceiver supports link lengths of

(X2-10GB-LX4)

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).

 

 

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.
