1 Introduction
This document covers :
- The application of Fischer FiberOptic Series electrical contacts and optical termini to electrical and fiber optic
cables (singlemode and multimode fibers)
- The assembly of fiber optic cable with a cladding size of 125 µm and having the cable structure described in
Fischer FiberOptic Series Cable Specifications
- The assembly of Fischer FiberOptic Series electrical contacts and optical termini and Rear Accessory sets
(Wire, Cable Clamp and Potting sets) to Fischer FiberOptic Series Hybrid (referred as FOH in the present
document)
Please read these instructions thoroughly before starting assembly.
