Overview
Because of the complexity of the HD system, there are a lot of hardware configurations.
Providing the procedures for every possible configuration goes beyond the scope of this
chapter. Therefore, this chapter only provides procedures about establishing internal and
external optical connections, as well as client and network connections.
Most traffic through the network element (NE) uses optical fibers. There are two classes
of traffic:
l Client traffic is terminated within the site. Most of this traffic uses 850 nm or 1310
nm wavelengths. Single-mode (SM) or multimode (MM) fibers may be used depending
on the module type.
l In most cases, network traffic is terminated in another ADVA Optical
Networking NE at a different site. For network traffic, SM fibers are used.
Pairs of fiber-optic jumpers are used to connect various optical modules installed in a
single HD shelf and within the NE (inter-shelf connections). The equipment shelves may
come with preterminated fiber optic cabling according to the system configuration
ordered.
The interconnection requirements are determined by your system configuration and can
be found in the optical cabling plan. The ports of the optical modules are connected with
respect to their logical sequence in the network. Optical connections are established from
client lines (CPE) via traffic modules through to the network line. In this way the fiber-
optic jumpers form the internal optical signal path of a single network element.
Labeling the optical connectors on the faceplate of each module is
explained in the appropriate traffic module chapter in PART1:
HARDWARE COMPONENTS.
