Active optical access technology Application bandwidth demand, high security communication enterprises and institutions access. It can also be used in the feeder section and wiring section of the access network, and mixed with other access technologies based on the use of wireless or copper wires.

AON (Active Optical Network) is a signal during transmission, the transmission network from the central office equipment to the use of the photoelectric conversion devices, active optoelectronic devices and fiber optic transmission equipment and other active optical fiber between user allocation unit. Active optical device comprises a light source (laser), optical receivers, optical transceivers, optical amplifiers (fiber amplifiers and semiconductor optical amplifiers).

Optical Access Network refers to the optical fiber as the transmission medium of the network environment. Technically fiber access network can be divided into two categories: active optical network (AON) and passive optical network (PON). Active optical network can be divided into SDH and PDH's AON; passive optical network can be divided into narrowband and broadband PON.

 The so-called all-optical network, refers to the entire process of data transmission between the exchange from the source node to the end-user nodes in the optical domain, namely a complete end to end optical path with no electrical intervention.
