Work safely on live optical fibre installations

Assessment tool

Version 1.0
Issue Date: May 2024


This unit describes the skills and knowledge required to work safely on a live optical fibre installation to test and commission a wavelength division multiplexing (WDM) system and to connect a splitter for fibre to the x (FTTx) deployment.

It applies to fibre technicians who engage in safe work practices as members of a team using emerging technologies to deliver very high-speed broadband capacity through the access network for the national broadband network (NBN) initiative.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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:

1310 nm

1490 nm

1550 nm.

Range of acceptable power levels must include:

-20 to + 2 dBm @ 1310 nm

-26 to -6 dBm @ 1490 nm

-11.5 to +5 dBm @ 1550 nm.

Maximum and minimum power losses must include:

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 must include:

delay

dispersion

optical attenuation and loss measurements

optical power levels

phase.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Scope work by obtaining project plan from appropriate personnel, and arrange for site access to comply with security arrangements 
Identify hazards, assess work health and safety (WHS) risks, and implement control measures according to workplace procedures 
Notify appropriate personnel of identified worksite safety hazards 
Determine FTTx equipment, components of optical distribution network (ODN) and WDM components, from project plan, for testing and commissioning 
Obtain required tools, safety equipment and materials to perform tasks safely and efficiently 
Select and use required personal protective equipment, and make site safe and secure for commissioning work 
Identify and avoid disconnection of other services 
Monitor implementation of control measures and revise as necessary 
Locate feeder fibre port to be connected 
Ensure power is turned off at source 
Connect connectorised splitter input fibres according to manufacturer specifications 
Arrange for power to be turned back on to newly connected feeder port 
Locate appropriate test points in ODN from manufacturer instructions for WDM testing 
Test live wavelengths for WDM tests according to safety precautions 
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 
Test losses between WDM outputs and individual line multiplexers (LM) for each wavelength, and determine if within maximum and minimum power losses 
Conduct all manufacturer specified acceptance tests 
Record and tabulate all test results for commissioning requirements 
Seal and secure any enclosures and cabinets 
Remove waste and debris from worksite and dispose of according to environmental requirements 
Notify appropriate personnel of job completion and obtain sign-off
