Description
This unit describes the performance outcomes, skills and knowledge required to install dense wavelength division multiplexing (DWDM) equipment in optical networks.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 install DWDM units
- 1.1. Determine the number of racks and DWDM units at each site by referring to installation documents
- 1.2. Determine the DWDM unit and equipment positions within the individual racks
- 1.3. Assemble equipment racks according to safe industry practice and manufacturer's instructions
- 1.4. Select tools and equipment
- 1.5. Prepare patch panels with connectors according to installation plan
2. Install DWDM units and associated cabling
- 2.1. Install DWDM unit in the designated rack position in order to maintain the planned link budget margin
- 2.2. Install patch panels and ancillary equipmentand connections into equipment rack in preparation for commissioning procedures
- 2.3. Insert circuit cards into specified slot locations in readiness for commissioning procedures, but do not seat cards into backplane nor lock into position at this stage
- 2.4. Connect optical fibre cables between circuit cards, optical multiplexers, adjoining DWDM units and patch panels according to manufacturer's specifications
3. Test power connections and complete the installation report
- 3.1. Measure the main and redundant power supplies to verify the correct polarity of the ground and power connections
- 3.2. Rectify any identified power wiring fault if applicable
- 3.3. Confirm that cooling fans, panel lights, indicator lights and alarms behave according to the manufacturer's prescribed specifications when power is applied
- 3.4. Complete the installation report and reinstate site

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:
conduct installation of DWDM systems and associated cabling according to plans and specifications
test power and ground connections
complete installation reports.
Context of and specific resources for assessment
Assessment must ensure:
suitable site for DWDM equipment installation
access to tools and equipment required for installation
a range of optical fibres to suit the installation.
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 installing a DWDM unit from a DWDM system together with installation of optical fibre interconnecting cables
review of DWDM installation report prepared by the candidate
oral or written questioning of the candidate to assess knowledge of DWDM installation practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTTEN3056A Install telecommunications network equipment
ICTBWN3088A Install optical fibre splitters in fibre distribution hubs.
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.
