Processing technology of digital wrapper′s overhead information based on FPGA
Wang Wen-sheng · Optical Communication Technology · 2011
Digital wrapper technology and applications in OTN of overhead information defined by digital wrapper technology are introduced in this passage firstly,which includes optical channel operation,management,maintenance and monitor,in order to provide reliable service.In view of the theory,a practicable scheme of digital wrapper overhead information's process based on FPGA is proposed in the paper to pick up and maintain the overhead information of digital wrapper.The whole architecture of scheme is also referred in the essay.Data interface block,data processing block and data transport block are also explained thoroughly in this paper.
