Abstract

The invention discloses a temperature control optical module and a working method thereof, the temperature control optical module comprises a semiconductor laser, a laser current driver, a semiconductor chilling plate, a first temperature detector, a second temperature detector and a temperature control circuit, the first temperature detector is suitable for detecting the working temperature of the semiconductor laser, and the second temperature detector is suitable for detecting the working temperature of the semiconductor laser. The second temperature detector is suitable for detecting the temperature of the environment where the temperature control optical module is located. The temperature control circuit is suitable for carrying out current adjustment on the semiconductor chilling plate according to the detection temperature difference value of the first temperature detector and the second temperature detector so that the semiconductor laser can be cooled. And the laser current driver is suitable for carrying out current modulation on the semiconductor laser according to the detection temperature of the first temperature detector so as to heat the semiconductor laser. The temperature control optical module reduces the temperature control power consumption and improves the temperature control efficiency.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a temperature-controlled optical module and a working method thereof. Background technique [0002] With the advent of the 5G era, major operators are vigorously promoting the construction of 5G networks in order to seize market opportunities. The frequency of 5G networks is much faster than that of 4G networks, but the higher the frequency of the base station, the faster its attenuation will be. Therefore, the density of the base stations of the 5G network is denser than that of the 4G network. Compared with the fronthaul and backhaul of the 4G network, the 5G network also adds mid-haul on the basis of the front-haul and backhaul. The mid-haul is to better control the increasing number of front-haul base stations. Based on the consideration of cost and optical fiber resources, operators have evolved the 5G fronthaul solution from the traditional optical fiber dire...
