Elements and Performance Criteria

  1. Prepare to use optical measuring instruments
  2. launch fibres, patch cords or enclosure adaptors
  3. consultation with client
  4. Conduct optical measurements
  5. Document measurement results

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) should be included.

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)



Knowledge Evidence
