Qualification -
Unit of Competency ICTBWN3205A - Use optical and radio frequency measuring instruments
Description This unit describes the performance outcomes, skills and knowledge required to set up and use hand-held optical and radio frequency (RF) communications instruments in order to perform installations, upgrades and fault-finding on optical and RF equipment. The complexity of the measurements performed is suitable for entry-level practitioners.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application Installation contractors, technical staff and field officers from telecommunications carriers, other private and public organisations and regulatory authorities apply the skills and knowledge in this unit. They combine technical skills with organisational and administrative skills.Field officers may be responsible for small projects such as forming routine field measurements on optical fibres in broadband optical networks, RF cables and equipment in broadband cable networks and satellite and terrestrial television systems.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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:

check and calibrate tools and instruments

perform optical measurements using hand-held instrument

perform RF measurements using hand-held instrument

comply with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

sites on which optical and RF measurements installations can be conducted

tools and equipment, currently used in industry, required for measurements.

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 performing an optical measurement using a hand-held instrument

direct observation of the candidate performing an RF measurement using a hand-held instrument

review of an oral and written report with completed documentation.

Guidance information for assessment

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

ICTBWN3100A Work safely with live fibre to test and commission a fibre to the x installation

ICTBWN3082A Perform tests on optical communication system and components

ICTRFN3055A Install a radio communications antenna and feedline

ICTRFN3175A Operate and maintain radio communications technical instruments and field equipment.

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.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

communication skills to:

liaise with internal and external personnel on technical and operational matters

relate to work associates, supervisors, team members and clients

literacy skills to interpret technical documentation such as manufacturer's instructions

safety awareness skills to:

apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities

select and use required personal protective equipment conforming to industry and OHS standards

work systematically with required attention to detail without injury to self or others, or damage to goods or equipment

task management skills to work systematically with required attention to detail and adherence to all safety requirements

technical skills to:

clean an optical connector to an acceptable industry standard

inspect an optical connector for contamination and determine if cleaning is necessary

operate a digital signal level meter (SLM) to measure RF signals on a broadband network or on a satellite or terrestrial television installation

operate a passive optical network (PON) power meter to measure PON signals of various wavelengths on fibre to the home (FTTH) and fibre to the premises (FTTP) network

Required knowledge

consequences of mating contaminated optical connectors

decibels, dBm and dBmV

optical and RF connector types

RF awareness and RF safety

RF spectrum and optical spectrum limits and allocations

safe handling procedures with optical fibres

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
