29.4Cable-connector installation

29.4.1 Introduction

This chapter contains a step-by-step description of the cable-connector installation process. The procedure consists of the following parts:

•Preparation (see section 29.4.3).

•Crimping the bush (see section 29.4.4).

•Stripping the copper wires (see section 29.4.5).

•Installing the socket contacts (see section 29.4.6).

•Stripping the optical fibers (see section 29.4.7).

•Installing the ferrules (see section 29.4.8).

•Assembling the connector (see section 29.4.9).

29.4.2 Cable types

There are two types of optical network cables:

•Type A cables in which the plastic optical fibers are located next to each other (see figure 29.5, which shows both cable ends).

•Type B cables in which the plastic optical fibers are located opposite to each other (see figure 29.5, both cable ends are identical).

29.4.3 Preparation

Proceed as follows:

1Cut the optical network cable to the required length using the cable cutter (tool 2).

Note

Due to light loss, the length of an optical network cable must be less than 50 m.

2Determine the cable type (see section 29.4.2), since some steps in the cable-connector installation

procedure depend on the cable type.

3Disassemble a network connector. A network connector consists of 10 parts (see section 29.3).

4Slide the back housing over the cable (see figure 29.6).
