1. INTRODUCTION

LightCrimp Plus ST fiber optic connector kits are

designed for use with 125--

m singlemode or

multimode glass fiber optic cable. These kits can be

used with any of the following media (paragraph of

assembly procedure is indicated next to media).

5.1. 900-

m Bare Buffered Fiber

5.2. 250-

m Coated Fiber

5.3. 2.0- to 3.0- mm Loose Jacketed Cable

5.4. 900-

m Easy Strip or Semi- Tight Buffered Fiber

Read these instructions thoroughly before assembling

the connector kits.

All numerical values in this instruction sheet

are in metric units. Dimensions are in

millimeters Figures are not drawn to scale.

Reasons for reissue of this instruction sheet are

provided in Section 6, REVISION SUMMARY.

2. DESCRIPTION

(See Figure 1)

Each connector kit consists of a connector assembly,

strain relief, inner eyelet, crimp eyelet, black tubing,

and clear tubing. Each kit is also supplied with a bare

buffer boot and small tubing to compensate for small

diameter cable. Also included, assembled onto the

connector, is a ferrule protective cover for the ferrule

(front of connector) and a plunger protective cap for

the plunger (rear of connector).

3. SAFETY PRECAUTIONS

NEVER look into the end of terminated or

unterminated fibers. Laser radiation is invisible

but can damage eye tissue. NEVER eat, drink, or

smoke when working with fibers. This could lead

to ingestion of glass particles.

Be very careful to dispose offi ber ends properly.

The fibers create slivers that can easily puncture

the skin and cause irritation.

DO NOT use defective or damaged components.

Replace them with new components.
