Install optical fibre splitters in fibre distribution hubs

Assessment tool

Version 1.0
Issue Date: April 2024


Technicians and cable installers who install and maintain optical network cables and equipment in access networks apply the skills and knowledge in this unit to provide services in Next Generation Networks (NGN) using emerging technologies.

NGN services include internet protocol TV (IPTV), video on demand (VoD), interactive TV, mesh networks and cloud computing.

This unit describes the performance outcomes, skills and knowledge required to install optical fibre splitters in fibre distribution hubs (FDH) as part of a fibre to the premises (FTTP) network.

Optical networks and FTTP are part of the strategies by service providers using wave division multiplexing (WDM) to deliver very high speed broadband capacity through the access network for the National Broadband Network (NBN) initiative.

Assessment by a TITAB-registered assessor is recommended.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

use optical power test equipment

measure optical signals at three WDM wavelengths

install splitter in the enclosure

connect input and out optical fibres to the splitter

test optical splitter

complete connection recording

comply with all related OHS requirements and work practices.

Context of, and specific resources for assessment

Assessment must ensure:

a telecommunications operations site where installation of optical fibre splitters in FDH may be conducted

a fibre distribution hub and relevant optical splitter

use of tools, equipment and personal protective equipment currently used in industry

relevant regulatory and equipment documentation that impacts on work activities.

Methods of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of candidate installing optical fibre splitters in FDH

direct observation of candidate applying all related OHS requirements and work practices

oral or written questioning to assess required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, e.g.

ICTBWN3090B Install lead-in module and cable for fibre to the premises

ICTBWN3100B Work safely with live fibre to test and commission a fibre to the x installation.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
