Fiber access can ensure that users with 10Mbps, 100Mbps, 1000Mbps high bandwidth, can be remitted directly connected to the backbone nodes. Mainly applicable to business groups of users and intelligent LAN area, high-speed access to high speed Internet. Available in three specific access to the user.

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.

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.

Fiber access refers to the complete optical fiber as a transmission medium between the central office and the users. Fiber access can be divided into active and passive optical access. Main fiber optic network is lightwave transmission technology. Development of optical transmission multiplexing quite rapidly, most have been in practical use.
