Analyse and integrate specialised optical devices in the network

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills and knowledge required to analyse and integrate specialised optical devices into existing optical networks to support higher bandwidths associated with Next Generation Networks (NGN).

It applies to individuals who work for telecommunications carriers, service providers or other private and public organisations, who have experience in optical transmission. They combine technical expertise with a range of analytical, research and planning skills to develop integration solutions for particular business needs.

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)

1.5 Prepare and submit the business case for adopting recommended integration solution

1.6 Prepare design plan with interconnection details to existing system and installation options and seek approval to proceed from customer

1.7 Undertake an impact risk assessment of the hardware integration with the network operations centre (NOC) and prepare for contingencies using contingency plan

2. Integrate specialised optical device in the network

2.1 Install and integrate specialised optical devices into existing network according to design plan

2.2 Test the network and evaluate results to verify optical network performance with integrated specialised optical devices in operation

3. Document integration of the specialised optical device in dense wavelength division multiplexing (DWDM) network

3.1 Produce an updated design plan and submit to customer with copies filed for later reference according to organisation’s policies

3.2 Prepare an evaluation report on network performance with specialised optical devices with recommendations for future enhancements

3.3 Notify NOC of job completion and obtain sign-off from appropriate person

Evidence of ability to:

analyse a specialised optical device and prepare a design to integrate it with a network

integrate and test the device

document integration to the network and recommend enhancements

submit relevant documentation to appropriate personnel

comply with all related work health and safety (WHS) requirements and work practices.

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 attenuation characteristics of optical fibres

summarise principles of operation of dense wavelength division multiplexing (DWDM)

describe features and operating requirements of test equipment, including:

a hand-held optical power meter

an optical spectrum analyser

a transmission test set

discuss dispersion characteristics of optical fibres

explain the role of dispersion compensation devices

explain standard electrostatic discharge precautions

explain functions of an optical add-drop multiplexer (OADM) and reconfigurable optical add-drop multiplexer (ROADM)

explain gain equalisation

summarise the International Telecommunications Union (ITU) wavelength grid for DWDM

explain the measurement of dispersion in optical systems

summarise optical amplifier operation

identify optical fibre connector types and characteristics

identify optical fibre types and characteristics

outline optical return loss (ORL)

explain path protection and protection switching

clarify protocols used on optical DWDM systems

explain the role of reflectance in optical systems

explain ring topologies and linear network topologies

explain specific WHS requirements that impact the safe inspection of optical connectors and the safe measurement of optical power from laser transmission systems

describe tunable laser sources and their characteristics.

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:

test equipment currently used in industry

manufacturer’s technical documentation, legislation, codes and standards.

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