Fibre Optic Services at a Glance

FDNS provides complete fibre optic infrastructure services from initial survey and network design through installation, fusion splicing, cable blowing, connector inspection, Tier 1 loss testing, OTDR analysis, CD/PMD characterisation, Ethernet and BERT testing, commissioning, maintenance and final documentation. Our work supports new-build, upgrade, fault-finding and specialist optical network projects across enterprise, data centre, telecoms, utility and renewable energy environments.

Fibre Optic Engineering and Deployment

FDNS delivers fibre infrastructure as a complete engineering service rather than treating installation, splicing and testing as separate activities. We assess the application, fibre type, route, containment, distances, connector interfaces, optical budget, resilience, future capacity and acceptance criteria before defining the delivery method.

Our capability includes conventional single-fibre and ribbon fibre installation, SpiderWeb Ribbon and conventional ribbon splicing, cable blowing, jointing, termination, end-face inspection, Tier 1 testing, OTDR, CD/PMD fibre characterisation, Ethernet/BERT/FEC testing and documented commissioning. We support building backbones, campuses, data centres, OPGW and utility networks, wind and solar sites, subsea cable landing stations and other high-capacity fibre environments.

The result is a standards-led, test-evidenced fibre platform designed around the service it must support, with clear labelling, traceable records and engineering documentation for operation, maintenance and future expansion.
