Problems solved by technology

However, due to the complexity of the burst communication mechanism of the PON system, the difficulty of this solution lies in: a) the sending and receiving circuits need to be controlled separately to provide high energy-saving efficiency; Able to communicate normally; c) Before the sending and receiving circuits enter the energy-saving mode, the working state is correctly saved and the saved information is quickly restored after entering the normal working state; d) When the receiving end of the ONU optical module is turned off, it cannot be established with the OLT Communication, how does the PON system control the energy-saving circuit at the receiving end

Abstract

The invention discloses a 10G single-fiber bidirectional optical module with an energy-saving function, comprising a 10G burst type sending-end energy-saving circuit, a 10G burst type sending-end retaining circuit, a 10G continuous receiving-end energy-saving circuit, a 10G continuous receiving-end retaining circuit and a microcontrol circuit. The invention has the advantages of low design cost and simple circuit design without influencing the normal communication of a 10G EPON (Ethernet Passive Optical Network) system and reduces the power consumption of the 10G EPON communication system by sufficiently utilizing the silence period of the optical module, thereby achieving the purposes of saving energy and reducing emissions.

Description

technical field [0001] The invention relates to 10G Ethernet passive optical network (10GEPON) energy-saving technology, in particular to an energy-saving functional circuit of a high-speed single-fiber bidirectional SFP+ 10G EPON ONU optical module. Background technique [0002] With the promotion and popularization of FTTx (fiber-to-user terminal) technology, high-speed broadband services are gradually changing people's life and work styles. SOHO will be very easy to implement, and home high-definition interactive film and television programs, telemedicine, and distance education are no longer far away. Bandwidth requirements continue to increase as living standards continue to improve. Since 10G EPON technology can effectively provide higher bandwidth, it has gradually become the preferred solution for operators and equipment suppliers for next-generation broadband services. However, the circuits and optical devices used in traditional 10G communication technology consum...
