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...

The optical fiber transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a fiber converter in many places. Products are generally used in actual network environments where Eth...

Application of EPON Technology in FTTx Access Network The EPON-based FTTx technology has the advantages of high bandwidth, high reliability, low maintenance cost, and mature technology. Secondly, it introduces the typical application model of EPON in FTTx, and then analyzes the key aspects of EPO...
