Course modules and practical training
This combined programme follows copper and fibre infrastructure from understanding the network layout through installation, termination, testing and handover. Technical instruction is supported by workshop activities using professional installation, splicing and test equipment. The emphasis is on the physical cabling systems used within enterprise buildings and data centres.
Enterprise cabling principles and network layouts
Explore the relationship between structured copper cabling and fibre infrastructure. Read network drawings, identify common topologies and distinguish horizontal cabling from backbone links. Consider how cabinets, racks, outlets, patch panels and optical distribution hardware connect the installation. Relate the layout to the work required, so individual cable runs and terminations can be understood as part of a complete infrastructure system.
Cable selection and practical route planning
Compare cabling choices against application, distance, bandwidth and performance requirements. Plan practical routes and consider containment, access, cable handling and the position of termination hardware. Discuss how the chosen route affects installation methods and cable management. Connect the planning decisions with the need to protect cables and leave an installation that can be identified, maintained and extended.
Structured copper cabling installation
Work with Category 5e, Category 6 and Category 6A cabling. Practise cable preparation, routing and installation, applying the handling methods demonstrated by the trainer. Explore the role of network outlets and horizontal cabling in enterprise infrastructure. Develop an organised working sequence that brings together cable preparation, placement and the termination tasks needed to create completed copper links.
Copper termination and patching
Prepare and terminate copper cables into patch panels and data outlets. Understand how cabinets, racks and patching arrangements connect installed links with the wider network. Practise managing cables around termination hardware, keeping connections accessible and maintaining a tidy installation. Recognise how termination workmanship and cable management affect the quality of the completed link and the investigation of subsequent faults.
Higher-performance copper cabling overview
Explore the applications of Category 7, Category 8.1 and Category 8.2 within the wider discussion of cabling performance. Relate cabling selection to the intended network application and its infrastructure requirements. This is an overview of these technologies; the confirmed practical copper installation scope centres on Cat 5e, Cat 6 and Cat 6A cabling and the associated termination hardware.
Fibre optic principles and cable preparation
Learn fibre terminology and the role of single-mode and multimode fibre within enterprise infrastructure. Explore OM3, OM4 and OM5 multimode systems. Practise preparing internal and external fibre cable constructions using suitable tools and handling methods. Connect cable preparation with the next stages of termination, fusion splicing and installation into the jointing and distribution hardware used during the programme.
Fibre termination, fusion splicing and enclosures
Develop practical fibre termination and fusion splicing skills. Work with jointing enclosures, fibre patch panels and optical distribution frames, understanding how fibres are managed between cable entry, splices and connection points. Practise an organised approach to preparation and fibre management so that the installation remains accessible and the completed connections can be identified during testing and handover.
Inspection, cleanliness and optical connectivity
Apply fibre handling, inspection and cleanliness practices when working with optical interfaces. Understand the relationship between fibre patching, connection quality and optical link performance. Use the training activities to connect careful preparation with the investigation of common installation defects. Discuss the importance of checking connections as part of the overall workflow for building and verifying fibre links.
Copper and fibre testing principles
Explore the different measurements used to check copper and fibre infrastructure. Use appropriate equipment to verify installed links and interpret basic results. Relate optical loss to fibre link performance, and connect copper test outcomes with installation and termination quality. Learn why test information needs to be associated with the correct link, so it can be reviewed alongside the installation records.
Fault identification and corrective work
Identify common installation faults and performance issues across copper and fibre systems. Use the available test information and a structured examination of the installation to guide investigation. Review connections, cable preparation and termination workmanship, then check affected links following corrective work. Develop a methodical approach rather than relying on replacing components without understanding the likely cause.
Practical assessment, documentation and handover
Bring the programme together through installation, termination, splicing and testing tasks. Record the work completed and the associated test information, preparing documentation that supports network handover. Practical activities and knowledge-based evidence contribute to assessment against the relevant qualification requirements. Successful completion depends on demonstrating the required outcomes across both parts of the programme.
Assessment combines practical activities with knowledge-based evidence across the fibre and copper elements. Attendance alone does not lead to an award; learners must meet the relevant assessment requirements.
Successful learners achieve the Open Awards Level 3 Award in Fibre Optics Installation and Testing (RQF) and the Open Awards Level 3 Award in Copper Datacoms Cable Installation and Testing (RQF). These are separate qualifications regulated by Ofqual.
On successful completion of the programme and required assessments, learners will be approved by COFNII as a Certified Network Enterprise Installer (CNEI), alongside the two Open Awards Level 3 qualifications. Discuss assessment requirements and learning support with Fibre Optics Training before booking.
