Replacing an Optical Module

An optical module implements optical-electrical conversion, enabling optical transmission
between a BTS3202E and other devices. You must disconnect the fiber optic cable from an
optical module before replacing the optical module. Disconnecting the fiber optic cable
interrupts the transmission of optical signals.

Prerequisite

The type and number of optical modules to be replaced are confirmed, and new optical
modules are ready.

Tools and materials, such as electrostatic discharge (ESD) gloves, M4 Phillips
screwdrivers, and an ESD box or bag, are ready.

Context

The optical module is installed on the OPT port on the BTS3202E.

Optical modules are hot-swappable.

It takes about five minutes to replace an optical module on the BTS3202E, which involves
disconnecting the fiber optic cable, removing the faulty optical module, inserting a new
optical module, reconnecting the fiber optic cable, and waiting for common public radio
interface (CPRI) links to resume.

Procedure

Step 1 Wear ESD gloves.

CAUTION

Take proper ESD protection measures; for example, wear ESD gloves, to prevent electrostatic
damage to the boards, modules, or electronic components.

Step 2 Record the connections of the optical module and fiber optic cable.

Step 3 Press the latch on the connector of the fiber optic cable, and then remove the connector from the

faulty optical module.
