Installing Fiber Connectors and 
LBOs

............................................................................................................................................................................................................................................................

Overview

Purpose

This appendix provides procedures for installing and removing Line 
Build Out units (LBOs) and fiber connectors onto input and output 
ports found on the Metropolis

® 

DMXplore optical circuit packs. 

...........................................................................................................................................................................

Contents

This chapter provides information on the following topics: 

Objectives

This appendix provides information to perform the following:

•

Install and remove LC-type LBOs onto and from LC-type ports.

•

Install and remove LC-type fiber connections.

...........................................................................................................................................................................

Fiber Cleaning

Refer to Appendix B, Fiber Cleaning for fiber cleaning information. Do 
not attempt to clean LBOs as they may be damaged by a cleaning 
attempt. Discard suspect LBOs and replace with a new unit.
