Problems solved by technology

If the power of the upwave optical signal is too large, it will cause the nonlinear effect of the optical fiber, resulting in transmission errors, and if the power of the upwave optical signal is too small, after the upwave optical signal is transmitted through the optical fiber, the power of the upwave Noise may not meet the reception requirements of the receiving end, resulting in transmission failure

Abstract

The embodiment of the invention discloses a power adjusting method and device and a storage medium. The method comprises the steps: detecting the lower wave power of at least one path of lower wave optical signal and the upper wave power of at least one path of upper wave optical signal; calculating the original power of at least one path of down-wave optical signal according to the down-wave power of at least one path of down-wave optical signal and the down-wave insertion loss of at least one path of down-wave optical signal; according to the original power of the at least one path of down-wave optical signal and the transmission insertion loss of the non-down-wave optical signal, calculating the transmission power of the non-down-wave optical signal; adjusting the upper wave power of the upper wave optical signal according to the target upper wave power and the transmission power of the non-lower wave optical signal for each path of upper wave optical signal in at least one path ofupper wave optical signal, wherein the target up-wave power is the up-wave power of the up-wave optical signal or the average up-wave power of the at least one path of up-wave optical signal.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to a power adjustment method, device and storage medium. Background technique [0002] In a multi-span (greater than 1 span) optical communication system, the nodes in the optical communication system have wave adding and wave dropping. If the power of the upwave optical signal is too large, it will cause the nonlinear effect of the optical fiber, resulting in transmission errors, and if the power of the upwave optical signal is too small, after the upwave optical signal is transmitted through the optical fiber, the power of the upwave Noise may not meet the reception requirements of the receiving end, resulting in transmission failure. Therefore, it is necessary to adjust and control the power of the upwave optical signal to avoid transmission errors and transmission failures. Contents of the invention [0003] In view of this, the embodiments of the...
