Application
This unit describes the skills and knowledge required to install a lead-in module and its associated cable for a fibre to the premises (FTTP) installation. Optical networks and FTTP are part of the strategies by service providers using wavelength division multiplexing (WDM) to deliver very high speed broadband capacity through the access network for the National Broadband Network (NBN) initiative.
It applies to individuals with specialist technical skills who work in teams to provide either underground or aerial services in next generation networks (NGN) using emerging technologies.
Work functions in the occupational areas where this unit may be used are subject to regulatory requirements. Refer to the ICT Implementation Guide Companion Volume or the relevant regulator for details of licensing, legislative or certification requirements.

Evidence of Performance
Evidence of the ability to:
safely use optical power test equipment
accurately measure optical signals at TWO wavelength division multiplexing (WDM) wavelengths
install lead-in module in the enclosure for both an aerial and an underground installation

identify the critical aspects of site engineering
explain specific WHS requirements relating to the handling of optical fibre and the use of laser light sources
explain WDM applications.
Assessment Conditions
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 fibre lead-in module, distribution pit, premises conduit and relevant optical network termination (ONT) unit
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.
