1.9 Cable Description and Installation

This section explains how to install fiber-optic, DS-3 (coaxial), DS-1 (CHAMP), and twisted-pair cables.

1.9.1 Cabling Types

ONS 15327 cables use cable guides at each side of the front of the shelf assembly to economize shelf
space and facilitate cable management. The following types of cables are used with the ONS 15327:
•
•
•
•

1.9.2 Cable Installation Overview

Because the ONS 15327 supports a large number of interfaces on the front panel, proper cable
management and the correct cabling sequence during installation are required.

1.9.2.1 Cable Guides

The ONS 15327 has cable guides located on each side of the front of the shelf assembly. The cable guides
ensure that the proper bend radius is maintained in the fibers and that all other cables are properly routed.
To remove cable guides, take out the screws that anchor them to the side of the shelf assembly.

Optical Cables: Optical cables connect to the SC connectors on the faceplate of the OC-12 and
OC-48 cards and the LC connectors on the OC-3 cards (described in the
section on page 1-23). Make sure the fiber cables do not bend excessively; maintaining a proper
bend radius prevents damage to the optical cable.
Coaxial Cables: Coaxial cables connect to the MICs on the ONS 15327 using BNC cable connectors.
Coaxial cables carry DS-3 traffic to and from the ONS 15327. The ONS 15327 supports up to three
transmit and three receive coaxial connectors on each shelf assembly.
CHAMP Cables: CHAMP cables connect to MICs on the ONS 15327 using CHAMP cable
connectors. Each CHAMP connector on the MIC supports one CHAMP cable connection for a total
of two connectors per node. Each CHAMP connector supports a maximum of 14 DS-1s. See the
"DS-1 Cable Installation" section on page 1-25
connectors.
Twisted-pair Cables: Twisted-pair cables connect to the ports on the Ethernet card, the Alarm and
BITS ports on the MICs, and the LAN port on the XTCs. The twisted-pair cables use RJ-45
connectors. The Ethernet card ports and the LAN ports use a standard straight-through cable.
Connecting to either the BITS or Alarm ports requires special cables described in the
Installation" section on page 1-27
