Abstract

The invention discloses a method and a device for adjusting the emitted light power of an optical module. The method comprises the following steps of: (1) transmitting and storing energy level data related to the transmission distance of the optical module to the optical module by using a communication protocol; (2) acquiring the energy level data by the optical module, and calculating a target emitted light power value corresponding to the energy level data; (3) adjusting the modulation current in a closed loop way according to the target emitted light power value to acquire a corresponding actual modulation current value when the actual emitted light power value equals to the target emitted light power value; and (4) adjusting the emitted light power of the optical module according to the actual modulation current value. With the method and the device provided by the invention, the dynamic adjustment of the emitted light power of the optical module can be realized, the power consumption of the optical module is reduced, and the generality of the optical module is increased.

Description

technical field [0001] The invention belongs to the technical field of optical communication, in particular relates to the adjustment of optical module parameters, and more specifically relates to a method and a device for adjusting the emitted light power of the optical module. Background technique [0002] With the continuous expansion of the transmission capacity and the continuous improvement of the transmission rate of the main line of the communication network, the optical fiber communication has become the main transmission means of the modern information network. In the current optical communication network, such as wide area network (WAN), metropolitan area network (MAN), local area network (LAN), etc., there are more and more types of optical transceiver modules as one of the core optoelectronic devices. The main function of the optical transceiver integrated module is to realize photoelectric / electrical-optical conversion. At the transmitting end, the electrical s...
