Fibre Optic Cable Installation

Fibre Optic Cable Installation Bristol

Rainbow Networks are one of the South West’s premier companies for fibre optic installation. From our base in Bristol, we are known for the design, installation, testing and maintenance of fibre optic networks throughout the UK.

Our qualified and highly experienced fibre optic engineers specialise in the network design, installation, fault finding and repairs of fibre optic networks for telecoms companies, retailers, business parks, college campuses and office IT infrastructure.

Our fibre experts can advise on the best fibre optic cabling to suit your business. Depending on the speed, bandwidth, application and the distance that cables need to run. We can recommend using single or multimode fibre optic cable. Single-mode fibre is available as OS1 and OS2. Multimode fibre is available in five variations OM1, OM2, OM3, OM4 and OM5.

Why work with Rainbow?

Rainbow Networks can install fibre optics links between business sites, we also connect high-performance networks, for example, for retailers with a large number of point of sale devices. Also, as fibre to the premises (FTTP) becomes increasingly available, more businesses are reaping the benefits of ultra-fast fibre optic connectivity.

Rainbow Networks are experienced at fibre installation subcontracting and can install FTTP for businesses in areas that have been enabled for FTTP, giving businesses a fibre connection from the telephone exchange straight to your business.

Businesses are increasingly turning to fibre optic cabling as they require higher bandwidth and faster performance from their IT infrastructure. Fibre optic cabling offers more bandwidth than traditional copper cabling which means that more devices can be added to networks supporting more users who can simultaneously run bandwidth-hungry applications such as video while managing the business using cloud-based services and running IP CCTV, building management and other IoT services across the fibre network.

How is fibre optic cabling installed?

The traditional method of installing fibre optic cables involved pulling the cable through cable ducts to reach its destination, blown fibre was introduced in order to make the installation process easier by blowing compressed air down the cable ducts thereby reducing the amount of friction between the fibre optic cable and the cable duct.

What are the benefits of fibre optic networks?

  1. Higher bandwidth – fibre cables provide more bandwidth than copper cables. Single-mode fibre offers twice as much bandwidth as multi mode fibre.
  2. Fast network speeds – fibre optic networks operate at far greater speeds than the latest Cat 7 cables.
  3. Greater distances – signals don’t degrade in the same way that they do with traditional cables which means they can be used over far longer distances.
  4. More reliable – fibre cabling isn’t affected by temperature variations and electrical interference.
  5. Better security – with ethernet cables it is possible for hackers to tap into cables and eaves drop to gather private company data. It is not possible to infiltrate fibre optic cables in the same way.

Fibre Optic Cabling FAQs

  • While copper cabling used to be the traditional choice, fibre optic is already the default choice for modern networks. The main advantage of fibre optic over copper is that it can transmit more data at higher speeds, with less distortion of signals too. Copper relies on electric pulses while fibre optic relies on light–and light is faster than electricity when it travels down wires.

    Unlike copper, fibre optic cables aren’t affected by electrical disturbances, so you won’t have to worry about them being close to motors or radios or shutting down with power failures. They’re also thinner and lighter, and they have a much longer lifespan than copper. Fibre optic is the future-ready approach, especially as our need for data keeps on rising.

  • Fibre optic cabling is a type of network cabling that’s known for being able to transmit data at extremely fast speeds even through long distances. For this reason, it’s already in most internet, phone, and TV systems all over the world.

    A fibre optic cable consists of extremely thin strands of glass or plastic that are bundled together then surrounded by additional layers of material for protection. Data is transmitted through the refraction of light inside the fibre optic cable. Transmission is around 30% slower than light because it doesn’t follow a straight path, instead bouncing along inside the cable.

    Fibre optic cables can already reach 10 Gbps at shorter distances, and the speed will keep going higher with advances in technology.

  • A fibre optic cable has four parts. The core of glass or plastic fibres is at the centre, while another layer called the cladding surrounds it. During data transmission, the light bounces between the core and the cladding. Around the cladding, there’s the buffer coating, which keeps the fibres safe from moisture or damage. Finally, the jacket serves as the outer covering of the entire cable.

  • Fibre diameter can vary, but all fibres are extremely thin. While some fibre optic cables can reach up to 20 mm, most cables have a maximum diameter of 0.5 mm, but the actual core and cladding are only at around 125 microns across, which is only a little thicker than human hair.

  • Fibre optic cabling is usually made of glass, but plastic is also possible. Glass is more common for communication networks because it can transmit a wider spectrum of light with less distortions, while plastic is more specialised, with applications in decorative or industrial lighting.

  • A major thing to consider is how accessible fibre is in your area. Most buildings in the UK now have access to fibre optic, with some already having fibre optic cabling built in while others have a fibre network close by. The distance of fibre resources to your building will determine how much work will have to be done. You can reach out to your landlord or the owner of your building or contact Rainbow Networks to check the fibre availability in your area.

  • Fibre cabling can last for 25 to 50 years. The first fibre optic networks were built more than 30 years ago, and they’re still working well and meeting their original specifications. Despite all of the major fibre networks around, no large-scale breakage has been observed. Of course, it also depends on the quality of the fibre cabling that you’re using. The top hazard would be extreme environmental factors such as exposure to water or animals, especially for fibre cabling on the ground. Still, all in all, fibre optic cabling is long-lasting and reliable, with a lifespan of several decades.

  • Fibre optic cables can be tight buffered or loose tubes. In tight buffered cables, coatings of plastic and acrylate are applied to each individual fibre, ensuring that the core is completely protected. Even when the cable is bent or submerged in water, the fibres will remain intact. Tight buffered cables can withstand being underwater or buried underground, and they’re optimised for indoor networks. In comparison, loose tube cables are designed to be durable in harsh outdoor conditions. Instead of plastic coatings, the fibres are surrounded by water-resistant gel that prevents them from reacting to high humidity. However, they can snap more easily when bent.
