Elements and Performance Criteria

Required Skills

Required skills

communication skills to liaise with internal and external personnel on technical and operational matters

literacy skills to interpret technical documentation

technical skills to

assemble and secure standard telecommunications equipment rack associated ironwork and optical fibre support ducting

clean optical fibre connector

examine optical fibre connector for contamination and assess whether cleaning is required

prepare and connect power and ground wires

use a digital multimeter to measure DC and AC voltage and to check continuity

Required knowledge

DWDM principles of operation

electrostatic discharge

optical fibre connector types and characteristics

optical fibre types and characteristics

specific OHS requirements that impact on the safe inspection of optical connectors and the safe measurement of optical power from laser transmission systems

Evidence Required

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

conduct installation of DWDM systems and associated cabling according to plans and specifications

test power and ground connections

complete installation reports

Context of and specific resources for assessment

Assessment must ensure

suitable site for DWDM equipment installation

access to tools and equipment required for installation

a range of optical fibres to suit the installation

Method 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 the candidate installing a DWDM unit from a DWDM system together with installation of optical fibre interconnecting cables

review of DWDM installation report prepared by the candidate

oral or written questioning of the candidate to assess knowledge of DWDM installation practices

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended for example

ICTTENA Install telecommunications network equipment

ICTTEN3056A Install telecommunications network equipment

ICTBWNB Install optical fibre splitters in fibre distribution hubs

ICTBWN3088B Install optical fibre splitters in fibre distribution hubs.

Aboriginal people and other people from a nonEnglish 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
