Apparatus, method and system for signal gathering and degathering

Abstract

The invention provides a device, a method and a system which are used for signal assembly and disassembly and applied to four-path 10G service. The assembly device comprises four optical passage data unit ODUx generation modules; each optical passage data unit ODUx generation module is respectively connected with one path of the four-path 10G service signals, used for carrying out the rate adaptation with one path of 10G service signals connected with each other, and outputting the ODUx signals with prearranged rates and types; wherein, the ODUx signal is ODU2, ODU1e or ODU2e signals; the four-path ODUx signals output by the four ODUx generation modules have the same rate and type; the assembly device also comprises an asynchronous assembly module which is used for assembling the output four-path ODUx signals to an OTU3 or an excessive-speed OTU3. The technical proposal of the invention realizes the mixed assembly of the 10G service signals with different multi-path service types, greatly reinforces the application flexibility and reduces the types of the single plate and the total system cost.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a device, method and system for converging and deconverging four-way 10G service signals. Background technique [0002] With the development of optical communication technology, the transmission rate increases rapidly and the transmission distance becomes longer and longer. In 10G and above 10G transmission equipment, 40G Optical Transport Network (OTN, Optical Transport Network) transmission will be widely used in the near future. [0003] At present, there have been a variety of OTU3 applications where four channels of 10G services are aggregated to a 40G rate. Since the currently known 10G rate services are as follows: STM64 (9.953Gbps), 10GELAN (10.3125Gbps), FC800 (8.5Gbps), FC1200 (10.51875Gbps), OTU2 (10.709Gbps), bps means bits per second, The rate of each service is slightly different, so for each aggregation application, four channels of the same type of 10G servi...
