A Kind of New Designing Method About High Speed Optcial Network Auto Protect Switch System

Abstract

In this paper, we research and develop a new type of optical fiber based on high-speed switching FPGA routing automatic protection switching device, its innovative USES high-speed electronic SWITCH high-speed exchange of FPGA design, will be 0 to 10 g digital optical signal photoelectric conversion amplification and rearrangement of the equipment selected by the high speed switching FPGA SWITCH protection, can for any important 0 to 10 g optical signal circuit after transformation (1 + 1) send after protect rearrangement of amplification, adopt concurrent optimization of transmission mode, automatic selection of high quality circuit signal in the microsecond time complete electrical SWITCH (far superior to the traditional common optical SWITCH SWITCH time), based on the development of commercial products for the national grid ehv transmission network users with high reliability, high performance of 0 to 10 g optical signal transmission channel protection. If there is no insertion loss, does not affect the original light path, also used in long-distance optical network transmission protection system in the west and subvert the traditional light path switching apparatus for at least 2 ~ 5 DBM large insertion loss. It overcomes the disadvantage of the traditional optical switch protection device.
