Optical access network (OAN) refers to the use of optical fiber as the main transmission medium to realize the information transmission function of the access network. With the development of optical transport networks and the explosive growth of data services.
The optical transceiver module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. The transmitting part is an electric signal with a certain bit rate input, which is processed by an internal driver chip to drive a semiconductor laser (LD) or a light emitting diode (LED) to emit a modulated optical signal at a corresponding rate.
Ethernet is a computer local area network technology. The optical access network includes remote equipment-optical network unit and central office equipment-optical line terminal, which are connected through transmission equipment.
The media converter is a device for signal conversion, usually referred to a fiber optic media converter. According to the network management, it can be divided into network management optical Media Converter and non-network management optical media converter.
