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!

ICTCBL322 - Install, test and terminate optical fibre cable on customer premises

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

Prepare for installation of optical fibre cable

  1. Access site according to enterprise procedures
  2. Inform appropriate personnel of identifiedworksite hazards
  3. Organise tools, cabling products, equipment and materials for given work
  4. Match optical fibre cabletype and connectors to installation environment and customer requirements
  5. Check proposed route and bend ratios according to manufacturer specifications and industry standards
  6. Test fibres in the cable on the drum for optical continuity as required
  7. Use personal protective equipment, including safety glasses, when working with bare fibre stripping/cleaving and utilise sharps disposal containers for bare fibre off cuts
  8. Place fibre patch leads in support pathway, avoiding pressure, crushing and bending

Clean and inspect connectors

  1. Test patch leads, before use, for continuity with a visible light source and inspect and clean connector end faces
  2. Test fibre connectors ensuring the circuit has no infra-red transmission (dark fibre)
  3. Ensure that associated equipment is labelled to inform others not to switch the equipment on or reconnect patch leads
  4. Remove connector dust cover and inspect for dust and damage using an optical microscope or video microscope
  5. Clean connectors with recommended cleaning tools, using wet and dry methods as required and re-inspect
  6. Replace connectors or patch cords when inspection reveals irreparable damage or contamination cannot be cleaned off
