Release 1

This version released with ICT Information and Communications Technology Training Package Version 5.0.

Application

This unit describes the skills and knowledge required to test optical communications systems and components using advanced optical test equipment. It involves using the optical time domain reflectometer (OTDR), optical spectrum analyser (OSA) and optical return loss (ORL) test set for performance testing and link budget calculation.

It applies to cablers who combine technical skills with organisational and administrative skills. They may be installation contractors, technical staff and field officers from telecommunications carriers or other private and public organisations or regulatory authorities.

No licensing, registration, legislative or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

ICTBWN307 Use optical measuring instruments

Unit Sector

Telecommunications – Optical Networks
