Professional Fibre Splicing, Termination & Certification Testing

Specialist Termination and Certification for the Industry

Not every contractor has the specialist equipment or trained engineers to handle fibre splicing, precision termination and formal certification testing. Vertex AV provides these services on a subcontract basis to M&E contractors, network installers, data centre builders and smart home integrators who need reliable, certified workmanship without the capital investment in fusion splicers, OTDRs and cable analysers.

Our fibre splicing service covers single-mode and multimode applications using fusion splicing for permanent, low-loss joints and mechanical splicing for rapid deployment or temporary connections. Every splice is housed in an appropriate enclosure, whether that is a wall-mounted fibre panel in a commercial building, an underground splice closure for external routes, or a high-density MPO cassette in a data centre. We carry portable fusion splicers with active cladding alignment that produces consistent splice losses below 0.1dB, and we verify every splice with an OTDR trace before declaring the link complete.

For copper cabling, we terminate Cat6 and Cat6a outlets, patch panels and consolidation points to the relevant standards. Our engineers are trained in proper wire management, strain relief and grounding practices that ensure long-term reliability. Every link is tested with a Fluke DSX-8000 cable analyser, which measures all parameters required for certification: insertion loss, NEXT, return loss, ACR-F, TCL and propagation delay. We do not simply run a basic wire map test: we perform full certification to the standard, because our clients need documentation that satisfies warranty conditions, insurance requirements and client handover processes.

In data centres and AI training facilities around Slough, Docklands and the M25 corridor, we install and terminate the high-density fibre trunks that connect GPU clusters, storage arrays and top-of-rack switches. These environments demand LC duplex, MTP/MPO and CS connector terminations with exacting cleanliness standards. We work in cleanroom conditions where required, using fibre cleaning tools, inspection scopes and dust caps to maintain connector integrity. The cable management in these facilities is as important as the terminations themselves: we route trunks through overhead ladder systems and under raised floors with proper bend radius control, labelling and segregation from power cabling.

We also provide fault-finding and audit services on existing installations. Using OTDR and TDR techniques, we can locate fibre breaks, bend radius violations, dirty connectors and macro-bends in under-floor cabling. For copper networks, we identify opens, shorts, split pairs and crosstalk issues that affect performance. These diagnostic services are valuable for building owners who have inherited cabling of unknown provenance, or for contractors who need to demonstrate that an existing installation meets the specification before adding new equipment. We provide detailed reports with distance-to-fault measurements, photographic evidence and recommended remediation steps.
