ICTOPN401
Install and test a dense wavelength division multiplexing system

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills and knowledge required to install dense wavelength division multiplexing (DWDM) equipment in optical networks.

It applies to individuals who interpret installation manuals and use technical skills to prepare for and conduct system tests and commissioning.

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Element

Performance Criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare to install DWDM units

1.1 Determine number of racks and DWDM units at each site by referring to installation documents

1.2 Determine 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 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 installation report

3.1 Measure main and redundant power supplies to verify correct polarity of ground and power connections

3.2 Rectify any identified power wiring fault if applicable

3.3 Confirm cooling fans, panel lights, indicator lights and alarms behave according to manufacturer’s prescribed specifications when power is applied

3.4 Complete installation report and reinstate site

Evidence of ability to:

determine the dense wavelength division multiplexing (DWDM) requirements for a site

install a DWDM system and associated cabling according to plans and specifications

test installation for operation, power and ground connections

analyse test results and rectify faults

complete and submit an installation report.

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

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

explain DWDM principles of operation

outline managing risk of electrostatic discharge

outline optical fibre connector types and characteristics

summarise optical fibre types and characteristics

outline specific workplace health and safety requirements that impact the safe measurement and inspection of optical connectors and optical power from laser transmission systems.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the Telecommunications – Optical Networks field of work and include access to:

tools and equipment requirement for installation

a range of optical fibres to suit the installation.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
