  2. Connect splitter input fibre to feeder cable
  3. Perform live WDM commission testing of ODN installation used in FTTx network
  4. Clean up worksite

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.

Operating wavelengths are:

1310 nm

1490 nm

1550 nm.

Ranges of acceptable power levels are:

-2 to + 2 dBm @ 1310 nm

-26 to -6 dBm @ 1490 nm

-11.5 to +5 dBm @ 1550 nm.

Maximum and minimum power losses are:

23.3 dB to 15.0 dB @1310 nm

21.6 dB to 8.0 dB @1490 nm

20.9 dB to 9.5 dB @1550 nm.

Acceptance tests are:

delay

dispersion

optical attenuation and loss measurements

optical power levels

phase.


Performance Evidence

Evidence of the ability to:

comply with all job requirements and work health and safety (WHS) regulations, standards and work practices

use optical power test equipment

evaluate test results

safely connect input and output optical fibres to the splitter

conduct live tests measuring optical signals at three wavelength division multiplexing (WDM) wavelengths on optical devices

conduct acceptance tests for commissioning

complete connection recording.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.


Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

identify the location and summarise the contents of relevant organisational policies and procedures

discuss personal safety issues

outline the propagation of light in optical communication systems

explain the role of transmitters and receivers in optical communication systems

identify the critical aspects of site engineering

describe the specific WHS risks and controls relating to the handling of optical fibre and the use of laser light sources

describe WDM applications.
