1) Establishment of Ethernet ring network in coal mining industry. Industrial Ethernet ring network can integrate various data, images, and voice into the ring network, including monitoring and scheduling data of various production automation subsystems in coal mines, industrial TV video images, digital voice, etc.

2) The establishment of various subsystems in the Ethernet ring network of the coal mining industry. Before the construction of the Ethernet ring network in the coal mining industry, it is necessary to carry out the construction of various subsystems such as power monitoring system, belt centralized control system, safety monitoring system, wireless communication system, personnel positioning system, and industrial television system above and below the mine. Then, these data will be uniformly connected to the Ethernet ring network, and the number of redundant fiber optic lines can be greatly reduced.

3) Telephone signal transmission. This is mainly used in long-distance telephone signal transmission within various mining enterprises.

4) Television signal transmission, which is mainly used in long-distance television signal transmission within various mining enterprises.

5) Urban area network signal transmission. This is mainly used in computer network signal transmission between the headquarters and its subsidiary mining enterprises.

6) LAN signal transmission is mainly used in office networks within various enterprises.

Through the application of fiber optic communication mentioned above, when using computers, the network is fast and stable. The large network can provide good feedback on environmental conditions, underground personnel operations, and equipment operation, and then transmit this information to the command and dispatch hub. It can effectively display the monitoring information status of each subsystem and the status of various links in coal production in real time with high quality, Subsequently, the relevant personnel responsible for scheduling, while timely controlling this information, achieved the goal of effective control and scheduling, thus effectively The security of enterprises.

Especially in the field of industrial automation, a series of products have been launched, such as 0-2M series optical module products, low-power 155M optical modules, low-power gigabit optical modules, low-power 10G optical modules, D57E6, DFBR1414, DFBR2412 and other products, which have replaced foreign brand products such as AVAGO and Finisar in many aspects.
