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!

ICTBWN308 - Work safely on live optical fibre installations

What evidence can you provide to prove your understanding of each of the following citeria?

Set up and prepare to work with live fibre

  1. Scope work by obtaining project plan from appropriate personnel, and arrange for site access to comply with security arrangements
  2. Identify hazards, assess work health and safety (WHS) risks, and implement control measures according to workplace procedures
  3. Notify appropriate personnel of identified worksite safety hazards
  4. Determine FTTx equipment, components of optical distribution network (ODN) and WDM components, from project plan, for testing and commissioning
  5. Obtain required tools, safety equipment and materials to perform tasks safely and efficiently
  6. Select and use required personal protective equipment, and make site safe and secure for commissioning work

Perform live WDM commission testing of ODN installation used in FTTx network

  1. Locate appropriate test points in ODN from manufacturer instructions for WDM testing
  2. Test live wavelengths for WDM tests according to safety precautions
  3. 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
  4. Test losses between WDM outputs and individual line multiplexers (LM) for each wavelength, and determine if within maximum and minimum power losses
  5. Conduct all manufacturer specified acceptance tests
  6. Record and tabulate all test results for commissioning requirements

Instructions to Assessors

Required Skills and Knowledge
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) areincluded. It is restricted to essential operating conditions and any other variables essential to the work environment.

Operating wavelengths must include:
