Description

technical field

[0001] The invention relates to an optical network user end equipment (ONT) in an asynchronous transfer mode passive optical network (ATM-PON) system, in particular to a new type of optical network terminal of the ATM-PON access network system. Background technique

[0002] In today's information age, people's demand for information is becoming more and more urgent, and the forms of demand are becoming more and more diverse. Facing the GHz bandwidth of the telecom backbone network, the development of the access network at the edge of the telecom network has been very slow, with backward technology and narrow bandwidth. Therefore, the development of the access network is imminent. The Asynchronous Transfer Mode-based Passive Optical Network (APON) combines the multi-service multi-bit rate support capability of ATM and the transparent broadband transmission capability of PON, and becomes an ideal fiber access solution in the 21st century due to its economy and...
