Traditional optical transceivers are point-to-point applications. Optical transceivers are installed at both ends of optical fiber, such as the most commonly used optical fiber Ethernet transceiver, which uses optical fiber to connect the computer networks at both ends; In such occasions as high-speed railway, tunnel and expressway, the point-to-point networking mode is obviously greatly limited. At this time, optical cables and equipment are required to form a chain network, and the node optical transceiver came into being: the center is a convergence device, corresponding to the communication signals transmitted by each node at the far end (telephone / video / Ethernet / serial port, etc.), It is reasonable and necessary in practical application to save optical cable investment and improve fiber core utilization.
The node type optical transceiver requires that the equipment should have at least 2 or more optical ports, and should be optionally equipped with breakpoint automatic protection function. When any node of the link fails, it can automatically shield the fault and directly connect to the next level node to ensure the normal communication of other fault free nodes.
