Expert fibre optic splicing and termination services
Fibre optic splicing and termination are the precision disciplines that determine how a fibre network actually performs. A poorly made joint or a badly seated connector introduces signal loss, reflectance, and intermittent faults that undermine even the best-specified cabling.
Done correctly, splicing and termination deliver low-loss, stable, fully certified links that perform to specification for decades.
As members of the Fibre Optic Industry Association, ACCL’s engineers carry out fusion splicing, mechanical splicing, and single- and multi-mode termination as part of our wider fibre optic installation service. Every joint and connector we complete is tested and certified, so you receive documented proof that the link meets the required standard.
Our fibre splicing and termination services
Whether you need a single emergency splice or thousands of terminations across a new installation, our engineers work to FIA standards and verify every connection.
Fusion splicing
Permanent, ultra-low-loss joints created by precisely aligning and fusing two fibres with an arc fusion splicer. The preferred method for long-haul, backbone, and high-performance single-mode links.
Mechanical splicing
Fast, reliable joints that align fibres within a precision sleeve. Ideal for rapid repairs, temporary restoration, and situations where fusion equipment cannot be deployed.
Single-mode termination
Termination of OS1/OS2 single-mode fibre for long-distance and high-bandwidth applications, including data centre, campus, and carrier-grade links.
Multi-mode termination
Termination of OM3/OM4/OM5 multi-mode fibre for high-speed in-building and short-reach links, terminated to the connector type your hardware requires.
Connector termination
Field and pre-polished termination across all common connector types, including LC, SC, ST, FC, and MTP/MPO for high-density environments.
Pre-terminated fibre solutions
Factory-terminated, tested plug-and-play assemblies for fast, low-risk deployment in data centre and comms room environments.
Fusion vs mechanical splicing: choosing the right method
The right splicing method depends on the application, the performance required, and the environment. Fusion splicing produces the lowest-loss, most durable joints and is the standard choice for permanent backbone, single-mode, and high-bandwidth links. Mechanical splicing is faster to deploy and requires no power, making it well suited to emergency fibre optic repair and temporary restoration. Our engineers advise on the most appropriate approach for your project and document the results either way.
Every splice tested and certified
A splice or termination is only complete once it has been verified. Every joint we make is inspected and tested, and we provide full fibre optic testing and certification so you have documented evidence that each link meets its insertion-loss and reflectance targets. This certification protects your investment, supports warranty claims, and gives you a clean record for compliance and handover.

What our clients think
We would like to take this opportunity to thank, You, Wayne and the team for such an excellent and professional implementation.
The organisation was fantastic and the way you worked within the building was great 😊 the business users did not even know what was going on in the building 😊 We would definitely not hesitate to use you guys again.

I have been dealing with Wayne at ACCL for some time now, as I was tasked by my employer to refurbish our server cabinets across 30 offices in London. I can’t begin to express how good Wayne and his guys are. They have replaced and refurbished a large number of our server cabinets so far, with no issues, all in a very timely manner.
They have done a highly professional job, have always kept in contact, and have given us advice/suggestions on what was needed when we weren’t too sure. I would highly recommend using ACCL for any IT/Cabling work.

Frequently Asked Questions – (FAQs)
What is the difference between fusion and mechanical fibre splicing?
Fusion splicing fuses two fibres into a single permanent, ultra-low-loss joint and is preferred for backbone and single-mode links. Mechanical splicing aligns the fibres in a precision sleeve, is faster and needs no power, and suits rapid repairs and temporary restoration.
Do you provide certification for fibre splicing and termination?
Yes. Every joint and termination is tested, and we provide full insertion-loss and reflectance documentation so you have certified proof each link meets standard.
Can you splice both single-mode and multi-mode fibre?
Yes — we terminate and splice OS1/OS2 single-mode and OM3/OM4/OM5 multi-mode fibre, to the connector type your equipment requires.
Do you offer emergency fibre splicing?
Yes. For damaged or cut fibre we provide rapid-response attendance through our fibre optic repair service.
Which connector types can you terminate?
All common types including LC, SC, ST, FC, and high-density MTP/MPO.
Are your fibre engineers certified?
Yes — ACCL is a member of the Fibre Optic Industry Association (FIA) and our engineers are trained and certified to industry standard.
