Multimode Fibre Repair in Greater London
SEG Ltd provides data cable repair and fault finding services across Greater London, diagnosing and fixing network cabling faults in offices, commercial buildings, and data centres throughout the capital. When network connections fail — data points stop working, links drop intermittently, speeds degrade, or fibre connections go down — you need an engineer with the right test equipment to systematically trace and resolve the fault.
Our London engineers carry Fluke cable analysers for copper fault diagnosis and OTDR testers for fibre optic fault location. Common London office faults include damaged cables from furniture or building works, failed terminations at patch panels, crossed pairs from incorrect termination, interference from power cables running too close, and fibre breaks from accidental damage in ceiling voids. We repair the fault and retest the link to confirm it meets specification.
If your network cabling has developed a fault, call us on 0330 133 9801 or submit a fault report. Our engineers will ask about the symptoms to begin diagnosing before attending site.

Multimode Fibre Repair FAQs for Greater London
For standalone commercial premises, a Dahua NVR system with HD or 4K cameras provides reliable coverage with smartphone remote viewing at a competitive price. For corporate environments needing multi-site management, analytics, or access control integration, we recommend Axis cameras with Milestone XProtect VMS.
Yes. Both systems support smartphone remote viewing. Dahua systems use the DMSS app for live viewing and playback. Milestone systems use the XProtect Mobile client. We configure remote viewing as part of every installation and ensure it works before handover.
We use Fluke cable analysers that test wire map, length, insertion loss, crosstalk, and return loss on copper cables. For fibre, we use OTDR (Optical Time Domain Reflectometer) testing that sends light pulses along the fibre and identifies the exact location of breaks, splices, and connectors. This pinpoints faults without physical inspection of the entire cable run.
In many cases, yes. If the damage is at a termination point — the patch panel or wall outlet — we reterminate. If there's a break mid-run, we can splice copper cables or fusion-splice fibre. However, if the cable has multiple faults or is degraded throughout, replacement is more reliable and cost-effective than patching.
Yes. We Fluke test and certify cabling regardless of who installed it. This is useful for verifying installations by other contractors, testing existing cabling before a building purchase, or diagnosing intermittent network issues where the cabling hasn't been properly tested before.
