T1600 Core Router Hardware Guide

As part of your routine maintenance, we recommend that you clean all exposed fiber-optic
array components each time you disconnect and reconnect a fiber-optic array cable, or
if the optical link is not functioning correctly.
NOTE: While you install the router or replace a fiber-optic array cable, small
deposits of oil, dust, and debris can enter the fiber-optic array ports, the
fiber-optic array cable connectors, and the loopback connectors and adapters
used to test the optical connections. These deposits can cause loss of light,
reducing signal power and causing intermittent problems with the optical
connection.
The following tools for cleaning the fiber-optic components are provided in the TX Matrix
Plus tool kit:
Dry cleaning tool (see Figure 92 on page 158). This tool uses a dry cloth to remove dust
and oil from the fiber optics.

emit laser light that can damage your eyes.
