Fibre optic fusion splicing for commercial buildings and sites
Single-mode and multimode fibre spliced on site by our own technicians, then tested and documented. For one damaged cable or for every termination of a new building.
What the service covers
A fusion splice joins two glass fibres permanently by melting them together with an electric arc. Done properly, it is the joint with the lowest loss and the longest life, which is why backbones, links between buildings and carrier entrance cables are spliced rather than joined with mechanical connectors.
Splicing is precise work, and most of the result is decided by preparation: how the cable is opened, how each fibre is stripped, cleaned and cleaved, and how the finished splices are protected and laid in the tray. We do that work with our own crew and our own equipment, as a stand-alone job or as part of a larger fibre or network project.
- Joining and extending cablesCable-to-cable splices in trays and enclosures, indoors and outdoors, when a route is extended or two sections meet.
- Terminations with pigtailsFactory-polished connectors spliced onto each fibre in the patch panel or fibre cabinet, for clean and repeatable connector performance.
- Single-mode and multimodeBoth fibre types, in the cable constructions found in commercial buildings and on campuses.
- Repair of damaged fibreThe break is located, the damaged section is cut out and the fibre is spliced back, then the link is tested again.
- Passive optical networksSplitters and distribution fibres spliced for PON, GPON and XGS-PON networks in buildings with many rooms or units.
- Work on existing cableSplicing and re-termination of fibre that another company pulled, or that has been in the building for years.
When fusion splicing is needed
- A new backbone or riser has to be terminated in the equipment rooms
- A cable was cut or crushed during construction or renovation work
- An existing fibre route has to be extended to a new floor, suite or building
- A carrier's entrance cable has to be continued to your equipment room
- Old connectors with high loss have to be replaced
- A tenant fit-out or a new tenant needs fibre from the building's backbone
Part of our fibre optic services
You can order this service on its own, including on fibre that another company installed.
How the splicing is done
The same sequence for one repair splice and for several hundred terminations.
- Review of the route and the fibre
We confirm the fibre type, the fibre count and where the splices will sit: which tray, which enclosure, which panel. On existing cable we test first, so that we know what we are starting from.
- Preparation
The cable is opened and secured, and the fibres are identified by colour. Each fibre is stripped, cleaned and cleaved to a clean, square end. This step decides the quality of the splice.
- Fusion and protection
The fusion splicer aligns the two fibres, fuses them and estimates the loss of the splice. A splice that does not meet the target is cut and made again. Each splice receives a protective sleeve and is laid in its tray with the correct bend radius.
- Testing and records
The finished link is tested, the trays, enclosures and panels are labelled, and the splice record is completed. You receive the results before the link carries traffic.
What you receive
A splice you cannot see has to be proven on paper. Every splicing job ends with a file that is yours to keep.
- Splice recordWhich fibre is joined to which, in which tray and enclosure, with the loss estimated by the splicer for each splice.
- Test resultsThe test results of each finished link, as agreed for the job: insertion loss, an OTDR trace, or both.
- LabellingTrays, enclosures, panels and ports labelled to match the record.
- As-built documentationThe route of the cable, the location of the splice points and the fibre assignments, as actually installed.
Common questions
Do you take splicing-only jobs on cable installed by another contractor?
Yes. Many of our splicing jobs are exactly that: the cable is in place and needs to be spliced, terminated and tested. We look at how the cable was left, tell you if anything has to be corrected before splicing, and quote the work.
What is the difference between a fusion splice and a mechanical connector or splice?
A fusion splice melts the two fibres into one continuous piece of glass. It has very low loss, reflects almost no light back and does not change over time. Mechanical splices and field-installed connectors hold the fibres together without fusing them; they are quicker to make, but they lose more light and are more sensitive to handling. For backbones and long links we recommend fusion.
How do I know the splices are good?
In two ways. The splicer estimates the loss of every splice as it is made, and a bad splice is redone on the spot. Then the finished link is tested. An OTDR trace shows each splice as an event with its measured loss, so the result does not depend on our word.
Can you repair a fibre cable that was cut?
Yes. We locate the break, expose sound cable on both sides and splice the fibres back, usually in an enclosure added at that point. If there is not enough slack, a short section of new cable is spliced in. The link is tested again before it goes back into service.
Can the work be done in an occupied building?
Yes. Splicing is clean, quiet work done at the equipment room or at the enclosure. A link that is being spliced is out of service during the work, so we schedule it around your business hours and tell you in advance which links are affected.
Do you splice both single-mode and multimode fibre?
Yes, both. Tell us the fibre type and count if you know them. If you do not, we identify the fibre on site before quoting.
