Elements and Performance Criteria
- Prepare to commission DWDM transmission system
- Implement hazard risk control measures
- Review system specifications and technical data by identifying system operating parameters
- Obtain and check tools and test equipment needed for the work
- Verify all necessary equipment is installed, and circuit cards and filler cards are correctly located and seated
- Check interconnecting fibres to optical multiplexers and shelves are intact and correctly routed
- Establish communication between computer and DWDM shelf
- Upload latest software release to each DWDM shelf in the network
- Commission DWDM transmission system
- Connect an optical test set and a physical optical loopback to the system, and select protocol compatible with DWDM hardware
- Check connection status and that test set data is passing correctly
- Monitor quality of received signal by setting performance monitoring (PM) features and retrieve PM counts
- Verify no errors are counted by the test set during a long term stability test while customer input signal is set to the worst case (minimum) power level
- Verify no alarms are generated during long term stability test period
- Dispose of antistatic packaging to minimise environmental impact
- Complete test and commissioning documentation
