More information should be gathered to make the power grid unified, robust and smart. Power grid transport network needs higher capacity and reliability. There are numerous SDH/PDH equipments employed in the present network. The requirement of upgrading from SDH network to WDM network is investigated. The specific features of power grid transport network are also studied in this paper. A green heuristic...
OSC (Optical Supervisory Channel) is a carrier of DWDM working statement information, including the information of network management, service and monitoring. In this paper, with the platform of ISE software and CPLD hardware, OSC data was successfully CMI encoded/decoded and scrambled/descrambled. The design has been applied in DWDM system reliably, which worked stably and showed a good performance.
