ICTBWN3090B
Install lead-in module and cable for fibre to the premises

This unit describes the performance outcomes, skills and knowledge required to install a lead-in module and its associated cable for a fibre to the premises (FTTP) installation.Optical networks and FTTP are part of the strategies by service providers using wave division multiplexing (WDM) to deliver very high speed broadband capacity through the Access Network for the National Broadband Network (NBN) initiative.FTTP services can be underground or aerial and may include hybrid fibre coaxial (HFC) installations.Assessment by a TITAB registered assessor is recommended.

Application

Technicians and cable installers who install and maintain optical network cables and equipment in Access Networks apply the skills and knowledge in this unit to provide services in Next Generation Networks (NGN) using emerging technologies.

NGN services include internet protocol TV (IPTV), video on demand (VoD), interactive TV, mesh networks and cloud computing.

Prerequisites

Not applicable.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to: use optical power test equipment measure optical signals at three WDM wavelengths install lead-in module in the enclosure for both an aerial and underground installation demonstrate successful completion of the procedures complete connection recording comply with all related OHS requirements and work practices.
Context of, and specific resources for assessment	Assessment must ensure: access to a telecommunications operations site where installation of lead-in module and cable for FTTP may be conducted a fibre lead-in module, distribution pit, premises conduit and relevant ONT use of tools, equipment and personal protective equipment currently used in industry relevant regulatory and equipment documentation that impacts on work activities.
Methods of assessment	A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct observation of the candidate installing lead-in module and cable for FTTP applying all related OHS requirements and work practices direct observation of the candidate measuring optical signals at three WDM wavelengths oral or written questioning to assess required knowledge.
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector, workplaces and job role is recommended, for example: ICTBWN3088B Install optical fibre splitters in fibre distribution hubs ICTBWN3100B Work safely with live fibre to test and commission a fibre to the x installation. Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs.

Licensing Information

Licensing, legislative, regulatory and certification requirements apply to working at heights. If an elevated work platform (EWP) is required, verify state or territory law requirements for a licence to operate an EWP. Users should confirm requirements with the relevant federal, state or territory authority.

If working at heights, achievement of the unit ‘CPCPCM2015A Work safely on roofs’ from the CPC08 Construction and Plumbing Services Integrated framework training Package fulfils this requirement.
