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 present application discloses a power adjustment method, device, and storage medium. The method includes: detecting the downwave power of at least one downwave optical signal and the upwave power of at least one upwave optical signal; Calculate the original power of the at least one downwave optical signal based on the downwave power of the signal and the downwave insertion loss of the at least one downwave optical signal; loss, calculate the transmission power of the un-dropped optical signal; for each of the at least one up-wave optical signal in the at least one up-wave optical signal, according to the target up-wave power and the transmission power of the un-down-wave optical signal The uplink power is adjusted; wherein, the target uplink power is the uplink power of the uplink optical signal or the average uplink power of the at least one uplink 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...
