Problems solved by technology

Then, the signal power of the optical signal arriving at the OUN device will become 3-15-5=-17dbm, and -17dbm still has a large margin relative to the receiving sensitivity of the ONU device-30dbm, that is, there is a large gap in the PON communication system. energy waste
[0005] Therefore, the prior art lacks a solution for collecting the energy margin of the optical signal of the PON communication system so as to utilize the energy margin and reduce energy waste

Abstract

The invention discloses a light energy collection device, a PON communication system and a light energy collection method, and the device is used for the PON communication system and comprises a firstoptical splitter, a second optical splitter and an energy storage module. An uplink interface of the first optical splitter is used for being connected with an ODN module, N downlink interfaces of the first optical splitter are correspondingly connected with N downlink interfaces of the second optical splitter, and M downlink interfaces of the first optical splitter are correspondingly connectedwith M first input ends of the energy storage module; an uplink interface of the second optical splitter is used for being connected with ONU equipment, and K downlink interfaces of the second opticalsplitter are correspondingly connected with K second input ends of the energy storage module; wherein N > = 1, M > = 1, and K > = 1. According to the invention, the energy margin of the optical signal transmitted by the PON communication system can be collected, so that energy can be utilized and the energy waste can be reduced.

Description

technical field [0001] The invention relates to the technical field of optical networks, in particular to a light energy collection device, a PON communication system and a light energy collection method. Background technique [0002] With the development of technology, passive optical network communication technology (PON communication technology) is more and more widely used due to its advantages such as long communication distance and large bandwidth. [0003] The PON communication technology corresponds to the ITU-T standard (that is, the International Telecommunication Union standard), and different PON communication systems have corresponding standards to specify the transmission power and reception sensitivity of the system ONU equipment and OLT equipment. For example, GPON communication technology corresponds to the G.984 standard under ITU-T. The G.984 standard stipulates that the transmission power of the ONU equipment under the Class C+ standard is 0.5dbm~5dbm, an...
