Two independent optical fiber channels are provided to support simultaneous data transmission and reception, thereby improving the efficiency and reliability of data transmission. The function of two optical fibers is realized through a double-core optical fiber connector, thereby reducing the use amount of optical fibers and connectors, and reducing the wiring cost and complexity. Parallel transmission of double-core optical fibers can significantly improve transmission efficiency and reduce transmission delay. In order to improve the installation efficiency and mark the double channels of the product, the smooth operation of the network is ensured. Domestic and foreign customers require that the product identification be consistent with the front of the connector, and the distance between the identification and the tail of the connector be consistent.
