Fibre Optic Cabling

All of the engineers employed at Cairn Solutions have been fully trained in the installation and termination of all types of fibre.

With over 30 years worth of experience in the installation of single mode and multi mode fibre systems, you can be rest assured that your installation will be to the highest standard.

What are Fibre Optics?

Fibre Optics is a technology that uses glass (or plastic) threads (fibres) to transmit data. A fibre optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.

Fibre optics have several advantages over traditional copper communications lines:

  • Fibre optic cables have a much greater bandwidth than traditional copper cable. Can carry more data than copper.
  • Fibre optic cables are less susceptible than its copper counterpart to interference.
  • Fibre optic cables are much thinner and lighter than copper cable.
  • Data can be transmitted digitally (the natural form for computer data) rather than analogically.

The main disadvantages of fibre optic is that the cables are expensive to install, more fragile than wire and are difficult to split.

Fibre optics has become a particularly popular technology for local-area networking. Most telecom's providers are steadily replacing traditional telephone lines with fiber optic cables. It is envisaged that in the near future almost all communications will employ fiber optics.

What types of Fibre are there?

There are in the main two types of fibre optic cabling, single-mode and multimode:

  • Multimode fibre is used for Local Area Networks (LAN) where the network links can be up to 2,000 meters. Two standard sizes of core are offered: 62.5 µm and 50 µm (with better performances). Multimode fibre have a graded index profile to reduce the dispersion of the signal during the transmission. The high size of the core is makes for easy connection and does not require high cost test equipment.
  • Singlemode fibre are able to transmit over longer distances. The installation is more delicate as they have a smaller core of 9 µm. This implies more precise connectors and test equipment.
