Description
This unit describes the performance outcomes, skills and knowledge required to test and commission optical transmission systems using dense wavelength division multiplexing (DWDM) technology.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.
Notes
Elements and Performance Criteria
1. Prepare to commission DWDM transmission system
- 1.1. Implement hazard risk control measures
- 1.2. Review system specifications and technical data by identifying system operating parameters
- 1.3. Obtain and check tools and test equipment needed for the work
- 1.4. Verify all necessary equipment is installed, and circuit cards and filler cards are correctly located and seated
- 1.5. Check that interconnecting fibres to optical multiplexers and shelves are intact and correctly routed
- 1.6. Establish communication between computer and DWDM shelf
- 1.7. Upload latest software release to each DWDM shelf in the network
2. Commission DWDM transmission system
- 2.1. Connect an optical test set and a physical optical loopback to the system, and select protocol compatible with the DWDM hardware
- 2.2. Check the status of the connection and that test set data is passing correctly
- 2.3. Monitor quality of received signal by setting performance monitoring (PM) features and retrieve PM counts
- 2.4. Verify that no errors are counted by the test set during a long term stability test while customer input signal is set to the worst case (minimum) power level
- 2.5. Verify that no alarms are generated during the long term stability test period
- 2.6. Dispose of antistatic packaging to minimise environmental impact
3. Complete test and commissioning documentation
- 3.1. Finalise documentation on commissioning test results
- 3.2. Present results to appropriate person according to established procedures

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
plan and coordinate commissioning
test and commission DWDM transmission system
complete test and commissioning documentation
comply with all related OHS requirements and work practices.
Context of and specific resources for assessment
Assessment must ensure:
access to sites on which testing and commissioning a DWDM transmission system may be conducted
use of test equipment currently used in industry
manufacturer's technical documentation.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
direct observation of the candidate performing test and commissioning
review of test and commissioning documentation completed by the candidate
oral or written questioning to assess knowledge of test and commissioning procedures.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTOPN5118A Plan and configure dense wavelength division multiplexing systems
ICTOPN5119A Perform acceptance and commissioning test on optical network
ICTOPN5120A Plan for an optical system upgrade and cut over
ICTOPN5122A Test the performance of specialised optical devices
ICTOPN5123A Analyse and integrate specialised optical devices in the network.
Aboriginal people and other people from a non-English speaking background may have second language issues.
Access must be provided to appropriate learning and assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.
In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
Where applicable, physical resources should include equipment modified for people with special needs.
