In order to improve the efficiency of relay protection and enhance the interoperability and stability of optical port direct connection of communication equipment,the synchronous digital system is used to extract the clock information of each directly connected node and the working signal of relay protection device,which is transmitted to the directly connected communication equipment through the optical port frame structure,and the anti electromagnetic interference ability is improved by removing the power transmission intermediate link,so as to improve the transmission efficiency of direct optical signal coding. The frame structure of relay protection and communication equipment is analyzed through mapping processing,positioning calibration and multiplexing operation.According to the performance parameters of optical port,on the basis of canceling photoelectric conversion equipment,integrate the direct connection technology between relay protection device and communication equipment to improve the effect of operation and maintenance.The experimental results show that the designed optical port direct connection technology of relay protection and communication equipment can effectively improve the information interoperability and stability,reduce the communication power consumption and power load,and improve the relay protection effect to a great extent.
