What is fibre optic jointing?

Fibre optic jointing is the process of permanently connecting two fibre optic cables to create a continuous optical path. Professional jointing ensures minimal signal loss, long-term reliability and stable network performance.

What is fusion splicing and why is it important?

Fusion splicing joins fibre optic cables by precisely aligning and fusing them together using specialist equipment. This method produces the lowest possible signal loss and is essential for high-performance fibre networks across the UK.

What is the difference between fibre optic jointing and splicing?

Fibre optic jointing refers to the overall process of connecting fibre cables, while splicing is the specific method used to join individual fibres inside the joint. Fusion splicing is the most common and reliable splicing technique.

When is OTDR testing required?

OTDR testing is typically required during network commissioning, fault investigation, acceptance testing and quality assurance. It is especially important for large fibre networks and external installations.

Why is fibre optic testing important after jointing?

Testing verifies that fibre joints meet performance standards and confirms there are no faults or excessive losses. Without testing, hidden issues can cause poor network performance or future failures.

How quickly can fibre jointing and testing be completed?

Timescales depend on project size and complexity, but we work efficiently to meet programme requirements and minimise disruption to live networks.

External Fibre Splicing Service

TNS has a wealth of experience in fibre splicing and testing. We have worked on the Openreach network via tier 1 & 2 providers delivering on spine (trunk) routes as well as PON and access networks.

Why Fibre Optic splicing requires skill

Fibre-optic splicing requires care to avoid damaging fibres during stripping of the external sheathing and tube preparation. External joint preparation can take time depending on whether it is an aggregation node, splitter node, or track joint—and how many cables are being prepared.

We have experience in fibre splicing on both underground and overhead networks.
Our knowledge extends to:

Ultra lightweight cables (ULW)
Overhead fibre drop cables
Trunk cables
Blown cable
Customer Splice points

Armoured cables
Blown fibre tube installation
Aggregation nodes
Blown fibre bundles
Customer Micro Enclosures

Track joints
Primary & Secondary splitter nodes
Riser enclosures
Optical distribution frames

External Job Packs

Working with suppliers, service providers and clients who provide job packs including network diagrams and splicing details, we splice accurately to the information provided. On completion, we provide as-built documentation as detailed in the work instruction pack.

External Network Testing

We use the latest test equipment to test the network and produce detailed test reports in an easy format so the client can understand them. Reports are produced in PDF format and .SOR so they can be read on another OTDR. We use enhanced software functions on all our testers, while still using standard OTDR for advanced verification.
