Abstract

The present invention relates to the field of communications. Disclosed is an optical switching architecture comprising cross-connect modules and add/drop modules connected to the cross-connect modules; the cross-connect modules comprise n groups of input ends and output ends of different dimensions; and the add/drop modules comprise first optical switch units connected to the input ends and the output ends, with transmitters and receivers connected to the first optical switch units. The present invention adds first optical switch units to an optical switching architecture, thus solving the problem that the optical switching architecture provided in the related art fails colorless and directionless requirements, and providing more flexible wavelength scheduling.

Description

technical field [0001] The invention relates to the communication field, in particular to an optical switching architecture. Background technique [0002] The optical switching architecture is used to exchange optical signals between different dimensions. It is the core module in the optical network switching system, and its performance determines the service capability of the entire optical network switching system. [0003] Due to the maturity of optical wavelength division multiplexing technology, the rapid growth of transmission capacity has brought pressure and power to the development of optical network switching systems. The scale of optical network switching systems in communication networks is getting larger and higher, and the operating speed is getting higher and higher. From the perspective of the development trend of the entire optical network switching technology, the future optical switching architecture needs to implement the switching characteristics of CDC....
