OPTICAL POWER EQUALIZATION METHOD AND APPARATUS |
摘要 |
Provided are an optical power equalization method and apparatus, which are applied to a flexible grid reconfigurable optical add drop multiplexer (Flex ROADM) system. The optical power equalization method includes: judging, according to an optical power monitoring result and an optical power control target value of an optical channel, whether optical power equalization needs to be performed on the optical channel; and when a judgement result is that the optical power equalization needs to be performed on the optical channel, performing equalization on an optical power of the optical channel and an optical power of each sub-carrier in the optical channel according to the optical power monitoring result. By means of the technical solution, the optical performance of the Flex ROADM system can satisfy the requirements. |
