Abstract

The invention provides a light module power supply control method, which is applied to a light module power supply control system consisting of a light module, a power supply control module and a system control module for controlling optical fibers. The method comprises the steps that the plugging state of the light module is detected, and if the light module is not plugged, forbidden signals are output for closing a conducting path of the light module; if the light module is plugged, whether the optical fibers are in position or not is detected, if the optical fibers are in position, gating signals are output to the power supply control module for conducting the conducting path of the light module; if the optical fibers are not in position, the forbidden signals are output for closing the conducting path of the light module; whether receiving signals of the light module are lost or not is detected, if the receiving signals of the light module are lost, the forbidden signals are output for closing the conducting path of the light module; if the receiving signals of the light module are not lost, the gating signals are output to the power supply control module for conducting the conducting path of the light source module. The light module power supply control method has the advantages that safety and reliability are realized during the plugging and the unplugging of the light module, the control is more convenient and reasonable, the damage to the light module is avoided, the existence of risk during the hot plugging and unplugging is reduced, and the energy consumption of the light module in the non-working state is reduced.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, and relates to a power control method and system, in particular to an optical module power control method and system. Background technique [0002] In the process of optical fiber transmission from the optical line terminal (OLT) equipment to the user, the optical module plays a very important role, because the optical module realizes the photoelectric conversion between the equipment and the optical fiber. The optical module is a precise device, and the increase in bandwidth also makes the usage of the optical module very large, resulting in energy consumption. The incorrect use of large-scale optical modules is also a great waste of energy. If the power supply of the optical module is connected to the power supply of the whole board, the stability of the optical module will be affected. Using a reasonable and correct method can reduce this waste and at the same time Control and manag...
