Abstract

The invention discloses a method and controller for capacity expansion and commissioning of a wavelength division multiplexing optical network, and belongs to the field of optical communications. The method includes: calculating the initial power of the wavelength service to be added according to predetermined rules, and adding one or more wavelength services according to the initial power; detecting the power of each newly added wavelength service during transmission, and calculating the power according to the detected value and the initial power respectively. Calculate the target power of each new wavelength service; calculate the end-to-end performance of the existing wavelength service and the end-to-end performance of each new wavelength service when each new wavelength service reaches its target power; When all the new wavelength services reach their target power, and the end-to-end performance of the existing wavelength services and the end-to-end performance of each new wavelength service meet their minimum threshold requirements, the power of each new wavelength service shall be measured. Adjustment. The present invention ensures that newly added wavelength services will not affect the performance of existing wavelength services in the network, and debugging efficiency can be effectively improved.

Description

technical field

[0001] The invention relates to the field of optical communication, in particular to a method and controller for capacity expansion and commissioning of a wavelength division multiplexing optical network. Background technique

[0002] The optical signals in the WDM (Wavelength Division Multiplex) optical network can be multiplexed, transmitted, amplified, routed and restored in the optical domain, making the WDM optical network a research hotspot in the field of optical communication. According to whether the network elements in the WDM optical network can perform electrical processing on optical signals, the WDM optical network can be divided into two types: Transparent (transparent) optical network and Opaque (opaque) optical network. For transparent optical networks, optical signals are always transmitted in the form of optical signals during transmission from the source network element to the sink network element, and signal regeneration, switching, and w...
