Fibre Optic Cabling

Fibre optic cable installation

In a world of high speed communications its even more important to have the support of a dedicated specialist company that can offer genuine fibre optic cable knowledge and expertise in fibre optic cable installation. Brexons has been a leading supplier of fibre optic cable installations in UK and Europe for more than 20 years, and our expertise has helped many clients improve their business performance and productivity.

As the demand for data capacity and transmission distances increases the ability of copper cabling to meet these demands diminishes. Fibre optic cabling provides the solution to that problem, delivering faster data transfer rates, with minimal decline over large transmission distances. Fibre optic cabling is ideal for businesses with large premises or multiple buildings.

Brexons have specialist knowledge and expertise in implementing single-mode and multi-mode fibre optic network infrastructures within a multitude of business sectors. Engaging Brexons you benefit from a full end-to-end solution, including bespoke fibre optic cable infrastructure design, installation and support.

Benefits of using fibre optic cabling

The installation of fibre optic cable is the main backbone link between equipment rooms and telecommunications closets, of all major fibre optic network solutions, campus network solutions, and where there is a need for large network data transfer within data centres. It is also is the main back bone link for Metropolitan Area Networks (MAN), Local Area Networks (LAN), Wide Area Networks (WAN) or if there is a cable length issue with using copper cable solutions like Cat5 or Cat6 cabling systems.

The real benefits of using fibre optic cabling for the data industry is its ability to transfer data at high speeds over long distances and the security benefit – it’s very difficult to tap into a fibre cable to read the data signals over a network. Fibre optic cables are immune to temperature changes and weather conditions, all of which can hamper the connectivity of copper cables. In addition, fibre does not carry electric current, so it is not affected by electromagnetic interference that can interrupt data transmission.

Fibre Optic Termination

Our Fibre Optic termination and testing service is offered to corporate end users as well as other communication providers who prefer to use our skilled services rather than invest in expensive termination equipment, fibre optic test equipment and costly engineer training. Both methods of termination are offered either Direct termination or Fusion Splicing of pre manufactured pigtail assemblies.

Direct Fibre Optic Termination

Epoxy and Polish – The connector ferrule is injected with epoxy and the fibre is inserted. The epoxy is cured at 80 degrees in fibre optic connector curing ovens. The excess fibre is scribed off flush with the connector face and then the remaining fibre and any epoxy is hand polished on lapping film to produce a low loss, scratch free finish to the ferrule/fibre face. On high fibre count installations we utilise fibre optic ferrule polishing machines to reduce installation time and ensure we always supply factory equivalent fibre optic terminations on-site.

Fibre Optic Fusion Splicing

A fibre optic fusion splicer is a device that uses an electric arc to fuse two optical fibres together at their end faces, to form a single fibre. The resulting joint, or fusion splice, permanently joins the two glass fibres end to end, so that optical light signals can pass from one fibre into the other with very little loss. Fusion Splicing allows us to join fibre optic cables or terminate cables with factory manufactured connectorised pigtails. We utilise Fujikura fusion splicers for single fibres and ribbon fibres using core alignment to ensure the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibres.

Fibre Optic Cable Transmission Distances

When choosing a fibre optic cable for a permanent trunk link you should consider three things, what is the distance of the cable run, what bandwitdh do I require now and what might I need in 5, 10 or 15 years time ie. what future proofing do I want? Installation costs can be much more than the cable costs, so looking ahead to future needs can pay back in the long run.

We recommend all new multimode runs use OM3 or OM4 cabling. OM2 can be disregarded as has been superseded by OM3 / OM4, and OM1 provides such poor performance we tend to only see it being used when it’s an addition to an existing OM1 installation (even then, one does not always have to stick to OM1). OM5 is a wide band multimode fibre – especially suited to allow WDM (wave division multiplexing) of 4 channels into two.

The chart shows the industry standard minimum distances achieved with each fibre type, however some cable manufacturers offer ‘enhanced’ cables which exceed these. It’s always best to check with us if you need to exceed these, so we can select the right manufacturers’ product.

fibre optic cable transmission distances

You can extend the Gigabit transmission distance for all types of multi mode fibre optic cable to 2km with proprietary Gigabit extenders which we supply. This is useful when you already have fibre cabling installed and additional performance is required.

By using singlemode Transceivers and Mode Conditioning patch cables, you can increase the range on OM1 fibre optic cable to 550m at Gigabit, and OM1/OM2 to 300m at 10Gigabit.
