Unit of Competency ICTBWN301 - Perform tests on optical communication system and components
Description
Employability Skills
Learning Outcomes and Application This unit describes the skills and knowledge required to test optical communication systems and components in the field using portable test instruments It applies to individuals who are installation contractors, technical staff and field officers from telecommunications service providers or other private and public organisations or regulatory authorities. They combine technical skills with organisational and administrative skills when working on broadband passive optical networks (PON), fibre to the x (FTTx) networks, hybrid fibre coaxial (HFC) networks and dense wavelength division multiplexing (DWDM) systems during installation, maintenance, commissioning and troubleshooting phases.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 site where installation of supporting infrastructure may be conducted

plant, tools and 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.
