Fibre optic cable is commonly used to link two communications cabinets together, often when located in separate buildings. This can be more practical than running Cat5e or Cat6 cable over long distances for normal wall sockets, especially when the range is limited to 100 metres.

An increased bandwidth of fibre optic cable allows lots of data to travel at once.

With multiple cores, one cable can be used for multiple services such as network cabling and telephony cabling. Using fibre optic cable can be one of the best ways to future proof your network.

Common Use

Fibre optic cables use light waves to transmit signals through glass threads, as opposed to copper cabling using low voltage signals. It can carry signals for multiple kilometres and can work at 100 Gbps depending on the type.

Fibre optics are very tough and do not corrode, and unlike copper it is not affected by electrical interference.

There are two mains types of fibre; multimode fibre (MMF) and singlemode fibre (SMF). SMF has a smaller core and can travel for longer distances with less power loss. MMF is generally more commonly used in businesses at the moment, as they have less long distance requirements.
