Chapter 1 System Overview

System Components

Note When designing your network, consider designs with 10-Gbps ITU tunable trunk cards as well as designs

with 2.5-Gbps ITU trunk cards. The type of ITU trunk card used affects the design parameters, such as

dispersion compensation, amplification, and available wavelengths.

The 10-Gbps ITU tunable trunk card has two version: nonsplitter and splitter. The nonsplitter version

has only one pair of optical connectors on the front panel, which connects to either the east or the west

OADM module, and can be used for unprotected, line card protected, or switch fabric protected

applications (see Figure 1-11).

Figure 1-13 Nonsplitter 10-Gbps ITU Tunable Trunk Card Architecture

The splitter version of the 10-Gbps ITU tunable trunk card has two pairs of optical connectors on the

front panel, which connect to the east and west OADM modules and is designed for splitter protected

applications (see Figure 1-12).
