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

determine the fibre loss between sites

calculate link budget and link margin

prepare DWDM shelf configuration and specifications

produce a configuration document

investigate an emerging DWDM technology

Context of and specific resources for assessment

Assessment must ensure

sites on which design of a DWDM system may be conducted

manufacturers technical documentation relevant regulations and specifications

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 undertaking DWDM calculations

review of data gathered reports and project plans prepared by the candidate

oral or written questioning to assess knowledge of design and configuring of DWDM systems

Guidance information for assessment

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

ICTOPNA Manage dense wavelength division multiplexing transmission system

ICTOPN6125A Manage dense wavelength division multiplexing transmission system

ICTOPNA Analyse optical transmission systems

ICTOPN6129A Analyse optical transmission systems.

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
