What is the network structure of the Optical Access Network (OAN) 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. It is connected to the service node through the optical line te...

With the continuous improvement of high-speed network construction and the need to build a digital smart life based on the “three gigabit” network capabilities, operators need longer transmission distances, higher bandwidths, stronger reliability and lower business operations Expenses...

The EPON network uses the FTTB method to form a network, and its basic network units are OLT and ONU. The OLT provides abundant PON ports for the central office equipment to connect to ONU equipment;ONU is the user equipment to provide corresponding data and voice interfaces to realize user servi...

ONU (optical network unit) optical node. ONU is divided into active optical network unit and library passive optical network unit.Generally, the equipment equipped with network monitoring including optical receiver, uplink optical transmitter and multiple bridge amplifiers is called optical node....

With the development of digital technology, optical communication technology and software technology and the wide application of TCP/IP protocol, telecommunication network, computer network and television network will merge with each other and become unified under IP capable of providing voice,da...

FTTH Fiber Circuit Classification The transmission layer of FTTH is divided into three categories: Duplex (dual fiber bidirectional) loop, Simplex (single fiber bidirectional) loop and Triplex (single fiber three-way) loop.The dual-fiber loop uses two optical fibers between the OLT end and the ON...
