FIBRE 101

Different Types of fibre:

Single Mode
Single mode fibre is optical fibre that is designed for the transmission of a single ray of light as a carrier and is used for long-distance signal transmission, since the core is smaller; less loss occurs thus distances of up to 80km are possible.

Multimode
Multimode fibre is optical fibre that is designed to carry multiple light rays concurrently, each at a slightly different reflection angle within the optical fibre core. Multimode fibre transmission is used for up to 500m because the light rays tend to disperse over longer lengths than this.

Dual Fibre
Dual fibre refers to typical fibre that runs using two fibres, one for sending (TX) and one for receiving (RX).

Single Fibre
Typical fibre applications use 2 fibres. For long distances, single fibre may be used to reduce the overall costing since half the fibre will be used to send the same amount of data. Single fibre converters still send data full duplex but they send data on one wavelength and receive data on another wavelength using the same piece of fibre.

ST Connector
ST stands for Straight Tip – a quick release bayonet style connector with a long cylindrical ferrule to hold the fibre.
