Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Commission DWDM transmission system

  1. Connect an optical test set and a physical optical loopback to the system, and select protocol compatible with DWDM hardware
  2. Check connection status and that test set data is passing correctly
  3. Monitor quality of received signal by setting performance monitoring (PM) features and retrieve PM counts
  4. 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
  5. Verify no alarms are generated during long term stability test period
  6. Dispose of antistatic packaging to minimise environmental impact
