Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills
communication skills to:
liaise with internal and external personnel on technical and operational matters
relate to work associates, supervisors, team members and clients
literacy skills to interpret technical documentation such as manufacturer’s instructions
numeracy skills to take and analyse measurements
planning and organisational skills to organise and maintain equipment
safety awareness skills to:
apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities
select and use required personal protective equipment conforming to industry and OHS standards
work systematically with required attention to detail without injury to self or others, or damage to goods or equipment
task management skills to work systematically with required attention to detail and adherence to all safety requirements
technical skills to:
clean an optical connector to an acceptable industry standard
inspect an optical connector for contamination and determine if cleaning is necessary
operate a digital signal level meter (SLM) to measure RF signals on a broadband network or on a satellite or terrestrial television installation
operate a passive optical network (PON) power meter to measure PON signals of various wavelengths on fibre to the home (FTTH) and fibre to the premises (FTTP) network
operate optical loss test set (OLTS) to measure loss of a fibre.
Required knowledge
consequences of mating contaminated optical connectors
decibels, dBm and dBmV
optical and RF connector types
RF awareness and RF safety
RF spectrum and optical spectrum limits and allocations
safe handling procedures with optical fibres.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Type of measurement may include: | optical measurement: detecting the presence of an active optical network terminal (ONT) determining absolute optical power (in dBm) determining insertion loss (in dB) determining relative optical power level (in dB) RF measurement: determining absolute RF power (in dBm) determining relative RF power level (in dB) determining relative RF voltage (in dBmV). |
Tools may include: | alcohol swabs dry type cleaning cassette for optical connectors electrical attenuators with suitable connectors lint free dry wipes metallic test leads and RF cables microscope for examining optical connector face optical connector adaptors: FC to LC FC to SC FC to ST SC to ST optical launch cable optical reference cable optical termination resistive termination RF connector adaptors: BNC to F type N type to BNC N type to SMA test leads. |
Instruments may include: | hand-held optical power meter hand-held optical source OFI-FTTx active ONT detector OLTS PON meter signal level meter (SLM). |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
