Perform tests on optical communication system and components


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 installation contractors, technical staff and field officers from telecommunications service providers or other private and public organisations or regulatory authorities.

These workers 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.


Elements and Performance Criteria

Elements

Performance Criteria

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare to use optical measuring instruments

1.1 Notify client about site access, security arrangements and location details for optical system and test purpose

1.2 Identify site hazards and notify appropriate personnel to make site safe according to enterprise requirements

1.3 Devise and implement risk control and safety measures when using high power laser test instruments and optical time-domain reflectometer (OTDR) associated with launch fibres, patch cords or enclosure adaptors

1.4 Prepare testing plan in consultation with client, indicating type of measurement at nominated wavelength, based on equipment specifications

1.5 Select appropriate tools and test instruments according to required measurement and enterprise practice

2. Conduct optical measurements

2.1 Set up test instrument according to manufacturer instructions, work health and safety (WHS) and environmental requirements

2.2 Test patch cords and/or launch/receive fibres are functional

2.3 Inspect and clean optical connectors

2.4 Use appropriate testing techniques to assess performance of optical system or component

2.5 Record test results and compare with standard test specifications according to manufacturer and enterprise guidelines

2.6 Evaluate test results and report on functionality of optical component or equipment, and performance of optical system

3. Complete optical measurement process

3.1 Make recommendations, based on test result interpretations, about optimising component and system performance

3.2 Clean work site and make safe according to enterprise requirements and customer satisfaction

3.3 Notify appropriate personnel of job completion for sign off and present test documentation, according to enterprise requirements

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance, but not explicit in the performance criteria.

Skill

Description

Reading

Interprets information from relevant sources to plan and identify all job requirements

Writing

Accurately completes relevant reports and documentation using clear and technically specific language

Oral Communication

Uses listening and questioning skills to confirm understanding of requirements, and participates in a verbal exchange of ideas and solutions

Uses appropriate, detailed and clear language to address key personnel and clients

Numeracy

Performs mathematical calculations to check, interpret and confirm results of system tests

Navigate the world of work

Complies with explicit policies and procedures, and explores and implements, where identified, the implicit expectations of policies and procedures

Understands roles and responsibilities for task and makes basic decisions about work completion parameters

Interact with others

Uses a limited range of accepted practices for communicating in a work environment

Recognises common cultural and other differences of people in the work context and accommodates these differences appropriately

Get the work done

Takes responsibility for planning, sequencing and prioritising tasks and own workload for efficiency and effective outcomes

Makes low-impact decisions within familiar situations, based on a range of predefined or routine solutions and evaluates the effectiveness of the outcome


Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. It is restricted to essential operating conditions and any other variables essential to the work environment.

Instruments/devices to be used must include:

laser light source including visual laser light source

laser power meter

passive optical network (PON) meter

optical time domain reflectometer (OTDR)

Optical measurements to be taken and recorded must include:

optical power levels

insertion loss of a passive device

end-to-end fibre loss (bi-directional)

splice loss

distance to fault, event, end of fibre using an (OTDR)
