Qualification
What you will be able to do
By the end of the course, you should be able to:
✓ Survey an installation site, identify cabling routes, outlet positions and cabinet locations, and record the information needed to plan the work.
✓ Read cabling layouts and specifications to establish the scope of a structured data cabling installation.
✓ Prepare risk assessments, identify installation hazards and select appropriate control measures before starting work.
✓ Estimate cable lengths and material quantities, prepare a materials list and calculate material costs for the planned installation.
✓ Select suitable cabinet sizes, allowing for patch panels, network equipment, cable management and future expansion.
✓ Explain how BS EN 50173 requirements apply to the structure and performance of generic cabling systems.
✓ Apply relevant BS EN 50174 installation requirements when planning cable routes, segregation, workmanship, quality assurance and documentation.
✓ Install Cat 5e, Cat 6 and Cat 6A copper cabling, maintaining appropriate routing, segregation and cable management.
✓ Prepare and terminate copper cables at patch panels and data outlets using suitable tools and termination techniques.
✓ Organise cabinets and patch panels to support tidy installation, clear identification and ongoing maintenance.
✓ Label cables, outlets and patch panels consistently so installed links can be traced and identified.
✓ Set up a cable analyser and test completed copper cabling links against the selected test requirements.
✓ Interpret cable analyser results to distinguish passing links from those requiring investigation or corrective work.
✓ Apply a systematic fault-finding method to identify installation and termination faults, correct them and retest affected links.
✓ Record test results and prepare clear handover documentation covering link identification, test outcomes and completed corrective work.
Course modules and practical training
This data cabling installation course combines theory with practical training, following the project from site survey and materials planning through to installation, certification testing and handover.
Network fundamentals, surveying and planning
Explore personal area networks (PAN), local area networks (LAN) and wide area networks (WAN), and how their purpose and coverage differ. Compare bus, tree, star and extended-star topologies, distinguishing physical cabling layouts from logical network connections. Relate star and extended-star arrangements to enterprise structured cabling, including outlets, patch panels, switches and backbone links. Work through drawings and site survey information to plan cable routes, outlet positions and cabinet locations, taking account of access, existing services and future requirements.
Risk assessments and preparation
Identify hazards associated with the installation work and prepare risk assessments with appropriate control measures. Plan the working sequence, organise tools and materials, and consider how to carry out installation activities safely in occupied commercial environments.
Materials selection and costing
Use installation layouts to estimate cable lengths and quantities of outlets, patch panels, containment and accessories. Prepare a materials schedule and calculate material costs, allowing for termination requirements, practical installation allowances and avoidable waste.
Copper installation, patch panels and modular terminations
Practical work with Cat 5e, Cat 6 and Cat 6A cabling, including punch-down patch panels, modular patch panels and data outlets using punch-down and tool-less jacks. Follow manufacturer instructions for cable preparation, pair twist preservation, strain relief and screened components where applicable. Practise T568A and T568B wiring colour codes, maintaining the specified scheme consistently and checking the completed wire map.
Cabinet specification, cable capacity and labelling
Specify floor-standing and wall-mounted cabinets against the number of incoming cables and required ports. Consider rack-unit capacity, patch-panel quantities, cabinet width and depth, cable entry space, bend radius, patching access, equipment depth, ventilation and future expansion. Plan cable managers for the volume and diameter of cables rather than rack height alone, and practise cable dressing and consistent outlet, cable and patch-panel labelling.
Standards, separation distances and quality assurance
Explore BS EN 50173, BS EN 50174 and ISO/IEC 11801 in relation to structured cabling specifications, installation and testing. Work through separation distances between data and power cabling, considering the cabling system, power circuits, containment and barriers, and relevant project conditions. Use the applicable standard and manufacturer guidance to establish the required separation rather than assuming one fixed distance for every installation. Review workmanship and documentation against the installation specification.
Power over Ethernet and connected devices
Consider how structured cabling supports wireless access points, IP cameras and VoIP phones using Power over Ethernet. Discuss cable bundling and temperature considerations, linking these to cable selection, routing and the intended network application.
Modular Plug Terminated Links (MPTL)
Practise field-installed modular plug terminations for links connecting directly to devices such as wireless access points and IP cameras. Compare MPTL with conventional permanent-link and channel configurations, and follow the plug manufacturer’s instructions for cable compatibility, pair arrangement and strain relief. Select the appropriate MPTL test limit and manufacturer-approved adapter configuration so the field-installed plug is included in the measurement. For Fluke DSX testing, this uses a permanent-link adapter at the patch-panel end and a category-matched patch-cord adapter at the plug end. Interpret the certification results and retain the MPTL test report with the link records.
Testing to ISO/IEC 11801 and BS EN 50173
Configure a professional cable analyser to test against the applicable ISO/IEC 11801 or BS EN 50173 profile, matching the specified cabling class, standard edition and permanent-link or channel configuration. Select suitable adapters and cable settings, run the certification test and compare each measured parameter with the selected standard’s limits. Interpret wire maps to identify opens, shorts, reversed pairs, crossed pairs and split pairs, checking consistency with the specified T568A or T568B termination scheme. Review length, insertion loss, return loss, NEXT, power-sum results, propagation delay and delay skew, including pass/fail status and performance margins. Investigate failed links, correct faults, retest and save traceable certification reports.
DC resistance unbalance and Cat 6A PoE testing
Understand DC resistance unbalance (DCRU) within a pair and between pairs, and why it matters when Cat 6A links carry Power over Ethernet. Examine how conductor resistance differences and poor connections can affect current sharing and PoE operation. Select a suitable analyser and test profile that includes the required resistance measurements, interpret the results and investigate failures. DCRU is relevant to other copper cabling categories as well as Cat 6A.
Practical exercises, documentation and handover
Bring the modules together through installation, termination, cabinet and testing exercises. Compile link identification and test records into a clear handover package, reviewing the completed work and preparing for the course’s practical and knowledge-based assessments.
On successful completion of the course and required assessments, delegates will achieve an Open Awards Level 3 vocational qualification in copper datacoms cable installation and testing. The qualification is regulated by Ofqual and recognises advanced practical competence in the installation, termination, testing and understanding of enterprise data cabling and structured cabling systems.
The qualification is also recognised by the Electrotechnical Certification Scheme (ECS) as an accepted Level 3 qualification route for the ECS Network Infrastructure Installer (Level 3) – Copper card. Delegates wishing to apply for an ECS card must also meet the additional ECS eligibility requirements, including the required industry experience and a current ECS Health, Safety and Environmental Assessment.
