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 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 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 DWDM hardware 2.2 Check connection status 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 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 no alarms are generated during 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 of ability to:
plan and coordinate commissioning
test and commission dense wavelength division multiplexing (DWDM) transmission system
complete commissioning documentation.
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 possible causes of alarms in long term stability test
summarise principles of operation of DWDM
explain standard electrostatic discharge precautions
outline features and operating requirements of test equipment including:
a hand-held optical power meter
a transmission test set
an optical spectrum analyser
describe functions of an optical add drop multiplexer
explain how to set up the following:
internet protocol (IP) addressing
subnet mask
dynamic host configuration protocol (DHCP)
default gateway
summarise the International Telecommunications Union (ITU) wavelength grid for DWDM
identify optical fibre connector types and characteristics
identify optical fibre types and characteristics
explain path protection and protection switching
summarise physical optical loopbacks and software loopbacks
describe protocols used on optical DWDM systems
summarise ring topologies and linear network topologies
outline specific health and safety requirements that impact the safe inspection of optical connectors and the safe measurement of 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:
test equipment currently used in industry
manufacturer’s technical documentation.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
