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.
Elements | Performance Criteria |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare to use measuring instruments | 1.1 Obtain approval for site access with client or site owner prior to site entry 1.2 Identify purpose of test and type of measurement required 1.3 Select appropriate tools and instruments according to required measurement 1.4 Check tools and instruments and calibrate to ensure accuracy 1.5 Obtain resources required 1.6 Devise and implement risk control measures in consultation with appropriate personnel, and document safety hazards |
2. Conduct measurements | 2.1 Follow site-specific safety requirements and enterprise work health and safety (WHS) processes and procedures 2.2 Set up test equipment according to manufacturer’s instructions and safe industry practice 2.3 Perform measurement using knowledge of appropriate testing techniques to assess overall system performance 2.4 Record and interpret test results and compare with standard test specifications 2.5 Clean work area and make safe according to established procedures |
3. Document measurement results | 3.1 Document test results and make recommendations to achieve optimum performance 3.2 Notify client of work completion |
This field allows for different work environments and conditions that may affect performance. 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) should be included.
Type of measurement must 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). |
Instruments must include: | hand-held optical power meter hand-held optical source handheld optical fiber identifier (OFI-FTTx) active optical network termination (ONT) detector operate optical loss test set (OLTS) passive optical network (PON) meter signal level meter (SLM). |
Evidence of the ability to:
comply with all job requirements and work health and safety (WHS) regulations, standards and work practices
check and calibrate tools and instruments
perform optical measurements using hand-held instrument
perform radio frequency (RF) measurements using hand-held instrument
operate the following equipment:
hand-held optical power meter
hand-held optical source
passive optical network (PON) meter
radio frequency (RF) signal level meter (SLM)
perform the following optical measurements:
detect the presence of an active optical network terminal (ONT)
determine absolute optical power (in dBm)
determine insertion loss (in dB)
determine relative optical power level (in dB)
perform the following RF measurements:
determine absolute RF power (in dBm)
determine relative RF power level (in dB)
determine relative RF voltage (in dBmV).
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:
identify and describe the various instruments used in measuring RF and optical frequencies
list the types of measurements and their respective interpretation for optical and RF frequencies
explain the consequences of mating contaminated optical connectors
correctly record and discuss data using the units decibels, dBm and dBmV
discuss the variations between optical and RF connector types
identify and describe the WHS hazards and risks, and describe controls when working with RF frequency measuring equipment
outline RF spectrum and optical spectrum limits and allocations
discuss safe handling procedures with optical fibres.
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 – broadband and wireless networks field of work and include access to:
a site where measuring instruments can be used
plant, tools and equipment currently used in industry
relevant regulatory and equipment documentation that impacts on work activities.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
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.
