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) |
