Unit Descriptor
This unit describes the performance outcomes, skills and knowledge required to install dense wavelength division multiplexing (DWDM) equipment in optical networks.
Application of the Unit
Telecommunications technical staff who install long haul or metropolitan area DWDM equipment apply the skills and knowledge in this unit. They install the DWDM unit and circuit cards and inspect, clean, and install optical fibres, connectors and associated equipment and prepare the system for subsequent testing and commissioning.
Licensing/Regulatory Information
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.
Pre-Requisites
Not applicable.
Employability Skills Information

Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
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 equipment and 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 |

Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
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. |
Range Statement
