Elements and Performance Criteria
- Set up and prepare for working with live fibre
- Obtain relevant legislation, codes, regulations and standards for compliance when conducting work
- Scope work by obtaining project plan from appropriate personnel and arrange for site access to comply with security arrangements
- Notify appropriate personnel of identified safety hazards at worksite
- Determine type of FTTx equipment, components of optical distribution network (ODN) and WDM components from project plan for testing and commissioning
- Obtain tools and safety equipment and materials to perform tasks safely and efficiently
- Select and use required protective equipment and make site safe and secure for commissioning work
- Create safe working environment by following safe work practices and identifying optical fibre hazards that could cause injuries when handling optical fibres and laser based equipment
- Connect splitter input fibre to feeder cable
- Follow workplace health and safety (WHS) and environmental requirements for given work, and identify and avoid other services
- Locate feeder fibre port to be connected
- Determine state (live or not) of fibre port to be connected and notify transmitter to ensure that power is turned off at source if fibre port is live
- Connect up connectorised splitter input fibres as instructed by manufacturer
- Arrange for power to be turned back on to newly connected feeder port
- Perform live WDM commission testing of ODN installation used in FTTx network
- Locate appropriate test points in ODN from manufacturer’s instructions for WDM testing
- Test live wavelengths for WDM tests following safety precautions
- Test optical signal strengths for operating wavelengths incoming into optical network termination (ONT) and determine if signal strengths are within range of acceptable power levels
- Test losses between WDM outputs and individual line multiplexers (LM) for each wavelength, and determine if within maximum and minimum power losses
- Conduct all acceptance tests as specified by manufacturer
- Record and tabulate all test results for commissioning requirements
- Clean up worksite
