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!

ICTBWN309 - Perform tests on optical communication system and components

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

Prepare to use optical measuring instruments

  1. Notify client about site access, security arrangements and location details for optical system and test purpose
  2. Identify site hazards and notify appropriate personnel to make site safe according to enterprise requirements
  3. Devise and implement risk control and safety measures when using high power laser test instruments and optical time-domain reflectometer (OTDR) associated with launch fibres, patch cords or enclosure adaptors
  4. Prepare testing plan in consultation with client, indicating type of measurement at nominated wavelength, based on equipment specifications
  5. Select appropriate tools and test instruments according to required measurement and enterprise practice

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) are included. It is restricted to essential operating conditions and any other variables essential to the work environment.

Instruments/devices to be used must include:

laser light source including visual laser light source

laser power meter

passive optical network (PON) meter

optical time domain reflectometer (OTDR)

Optical measurements to be taken and recorded must include:

optical power levels

insertion loss of a passive device

end-to-end fibre loss (bi-directional)

splice loss

distance to fault, event, end of fibre using an (OTDR)
