Work safely with live fibre to test and commission a fibre to the x installation

Assessment tool

Version 1.0
Issue Date: August 2018


This unit describes the skills and knowledge required to work safely on a live optical fibre installation to test and commission a wavelength division multiplexing (WDM) system or connect a splitter for fibre to the x (FTTx) deployment.

It applies to individuals who engage in safe work practices as members of a team using emerging technologies to deliver very high speed broadband capacity through the access network for the National Broadband Network (NBN) initiative.

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

safely connect input and output optical fibres to the splitter

conduct live tests measuring optical signals at three wavelength division multiplexing (WDM) wavelengths on optical devices

conduct acceptance tests for commissioning

complete connection recording.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

identify the location and summarise the contents of relevant organisational policies and procedures

discuss personal safety issues

outline the propagation of light in optical communication systems

explain the role of transmitters and receivers in optical communication systems

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the telecommunications – broadband and wireless networks field of work and include access to:

a WDM system and relevant optical splitter

tools, equipment and personal protective equipment currently used in industry

relevant regulatory and equipment documentation that impacts on work activities.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
