Problems solved by technology

In the prior art, the heating device installed in the noise filter device needs to use air radiation to transfer heat, the heating speed is very slow and uneven, and it is difficult to maintain the stable and normal operation of the optical fiber in harsh environments. The transmitted signal is attenuated so that the signal is distorted
In addition, when the laser is turned on instantly, a strong optical noise signal will be generated, which will further affect whether the optical fiber signal can be transmitted stably when passing through the heated part of the optical fiber, and then whether the signal receiving end can obtain correct and complete transmission of information affects

Description

technical field [0001] The invention relates to the technical field of optical fiber filtering, in particular to an optical fiber filtering device. Background technique [0002] The optical fiber in the prior art will carry some optical noise signals due to external influences during signal transmission, and these optical noise signals will affect the clarity of the optical fiber signal during transmission. In order to solve this technical problem, the method of installing a noise filter device at the initial end of optical fiber transmission is adopted in the prior art to achieve the technical effect of reducing optical noise as much as possible. Although the above structure can filter out optical noise to a certain extent, the noise filtering effect still needs to be further improved. The residual optical noise signal still has a certain influence on the transmitted signal, and this effect is more prominent when the laser works instantaneously. . Furthermore, the optimum...
