AON

Active Optical Network – a general term that describes any network configuration in which Multiplexors (MUXs), either in a Central Office or a cabinet are used to connect multiple Optical Network Units (ONUs) via dark fibres. A Point to Point network is an AON with an emphasis on direct connection to each ONU, in which case each dark fibre provides a direct point-to-point physical connection between the MUX in a Central Office and each ONU.

GPON

Gigabit Passive Optical Network – a specific standard for connection of Optical Line Terminals (OLTs) to multiple Optical Network Units (ONUs) in which groups of ONUs are connected to an OLT using a shared dark fibre configuration. This is described in the ITU-T G.984 standard.

GPON Splitter

A specialised piece of network equipment that connects a single dark fibre from one side to many dark fibres on the other. It is used in the GPON network configuration to allow many Optical Network Units (ONUs) to share a single port on an Optical Line terminal (OLT) – hence the use of the word “Splitter” – splitting one dark fibre into many.

Ultra-fast broadband. Broadband is a technology that allows data to be transmitted at high speeds between the internet or applications on computers in the ‘cloud’ and your computer or mobile phone. It allows a greater volume of data to be transmitted much more quickly than dial-up internet because it can handle a greater range of frequencies – or, in geek speak, a higher ‘bandwidth’. This is where the term ultrafast broadband comes from.
