Transceiver Type

Cabling Guideline

 

 

CX4

The Cisco CX4 transceiver supports link lengths of up to 49.2 feet

(XENPAK10GB-CX4 and

(15 m) on CX4 cable. Cisco offers four CX4 cables:

X2-10GB-CX4)

CAB-INF-28G-1= (1 meter cable)

 

 

CAB-INF-28G-5= (5 meter cable)

 

CAB-INF-28G-10= (10 meter cable)

 

CAB-INF-28G-15= (15 meter cable)

 

 

LRM

The Cisco LRM transceiver supports link lengths of 220 meters on

(XENPAK-10GB-LRM and

standard Fiber Distributed Data Interface (FDDI) grade multimode fiber

X2-10GB-LRM)

(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) with dual SC connectors.

 

CAB-MCP50-SC= —Mode-conditioning patch cable (50 microns)

 

with dual SC connectors. No mode-conditioning patch cord is

 

required for applications over OM3 fiber cable.

 

 

USB Ports

Supervisor Engine 32, Supervisor Engine 32 PISA, Supervisor Engine 720-10GE, and Supervisor Engine 2T have two USB ports located on front panel. One port is designated for host use and the other as a device port. A host USB port can be used to plug in devices such as a PC, while device ports can be used for attaching Flash Memory Key devices.

Note Currently the two USB ports are not enabled on the Supervisor Engine 32, Supervisor Engine 32 PISA, and Supervisor Engine 720-10GE. The 5-pin USB port on the Supervisor Engine 2T is enabled. The second USB connector is not currently enabled.

Copper and Fiber-Optic Connectors

This section describes the types of copper and fiber-optic connectors that are used with the supervisor engines.

RJ-45 Connector

The RJ-45 connector (see Figure B-2) is used to connect a Category 3, Category 5, Category 5e, Category 6, or Category 6a FTP or UTP cable from the modem or terminal to the supervisor engine console port, or the network to a copper uplink port if the uplink port has a 1000BASE-T copper transceiver installed in it.
