TW2000 integrated ring network optical transceiver

(Can simultaneously provide Ethernet/telephone voice (including 2/4W audio/magnet/E&M/hotline)/serial port/switch/E1)

Traditional optical transceivers are used for point-to-point applications, with the transceivers installed at both ends of the fiber optic cable. For example, the most commonly used fiber optic Ethernet transceiver uses fiber optic cables to connect the computer networks at both ends; In scenarios such as power, water conservancy, and backbone transmission networks, the point-to-point networking method is clearly limited. In this case, optical cables and equipment are required to form a ring network, and optical equipment requires a ring network optical transceiver: the center is an aggregation device that corresponds to the communication signals (telephone/video/Ethernet/serial port, etc.) transmitted by various remote nodes, maximizing the savings in optical cable investment and improving fiber core utilization. This is reasonable and necessary in practical applications.
The ring network optical transceiver requires the equipment to have at least 2 or more optical ports, and should be able to achieve self-healing protection function. When any node on the link fails, it can automatically choose other routes to communicate with the center, ensuring normal communication of fault free nodes.

According to practical application scenarios, ring network optical transceivers can be divided into:

New serial port ring network application

In order to meet the ring network requirements of the wind farm, a self-healing Ethernet ring optical transceiver needs to be installed in the relay protection room of the substation. The two fiber interfaces of the optical transceiver are respectively connected to the intelligent box transformer monitoring unit installed in the wind farm box transformer to form a ring connection. The electrical port of the optical transceiver is connected to the 100M Ethernet switch of the monitoring system in the substation.
