Unit Descriptor
This unit describes the performance outcomes, skills and knowledge required to work safely on a live optical fibre installation to test and commission a wave division multiplexing (WDM) system or connect a splitter for fibre to the x (FTTx) deployment.
Optical networks and FTTx are part of the strategies by service providers using WDM to deliver very high speed broadband capacity through the access network for the National Broadband Network (NBN) initiative.
Application of the Unit
Technicians and cable installers who install and maintain optical network cables and equipment in Access Networks apply the skills and knowledge in this unit to provide services in Next Generation Networks (NGN) using emerging technologies.
NGN services include internet protocol TV (IPTV), video on demand (VoD), interactive TV, mesh networks and cloud computing.
Licensing/Regulatory Information
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.
Pre-Requisites
ICTWHS2170B Follow work health and safety and environmental policy and procedures
Employability Skills Information
This unit contains employability skills.

Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
|
1. Set up and prepare for working with live fibre |
1.1 Obtain relevant legislation, codes, regulations and standards for compliance when conducting work 1.2 Scope the work by obtaining project plan from appropriate personnel and arrange for site access to comply with security arrangements 1.3 Notify appropriate personnel of identified safety hazards at the worksite 1.4 Determine type of FTTx equipment, components of optical distribution network (ODN) and WDM components from project plan for testing and commissioning 1.5 Obtain tools and safety equipment and materials to perform tasks safely and efficiently 1.6 Select and use required protective equipment and make site safe and secure for commissioning work 1.7 Create a safe working environment by following safe work practices and identifying optical fibre hazards that could cause possible injuries when handling optical fibres and laser-based equipment |
|
2. Connect a splitter input fibre to the feeder cable |
2.1 Follow occupational health and safety (OHS) and environmental requirements for the given work and identify and avoid other services 2.2 Locate the feeder fibre port to be connected 2.3 Determine the state (live or not) of the fibre port to be connected and notify transmitter to ensure that power is turned off at the source if the fibre port is live 2.4 Connect up connectorised splitter input fibres as instructed by the manufacturer 2.5 Arrange for power to be turned back on to the newly connected feeder port |
|
3. Perform live WDM commission testing of a ODN installation used in FTTx network |
3.1 Locate the appropriate test points in the ODN from manufacturer’s instructions for WDM testing 3.2 Test live wavelengths for the WDM tests following safety precautions 3.3 Test the optical signal strengths for the operating wavelengths incoming into the optical network termination (ONT) and determine if signal strengths are within the range of acceptable power levels 3.4 Test the losses between the WDM outputs and the individual LM for each wavelength and determine if within maximum and minimum power losses 3.5 Conduct all acceptance tests as specified by manufacturer 3.6 Record and tabulate all tests results for commissioning requirements |
|
4. Clean up work site |
4.1 Seal and secure any enclosures and cabinets 4.2 Remove waste and debris from worksite and dispose of according to environmental requirements 4.3 Notify appropriate personnel of job completion and obtain sign off |

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
|
|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
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. |
