LT8978b V1 HIEE320639R0001

LT8978b V1 HIEE320639R0001 can be composed of a variety of fiber optic networks. Logical independent dual-bus electrical interface, can realize the backup of the electrical interface or a single device to access the dual-redundant system; using a point-to-point network can be achieved through the fiber-optic connection between the two CAN bus segments; using a dual optical port chain network of fiber-optic bus to achieve multiple segments of the CAN bus connection (200);

LT8978b V1 HIEE320639R0001 using dual optical port to achieve dual-fiber ring network redundancy function, when a fiber optic failure, the system will rebuild the network link within 15ms to protect the system’s normal communications, to achieve self-healing signal transmission protection function, the system will automatically recover after the removal of network failures, no setup, no need for the root node, to quickly complete the network into a ring and unlock the loop! This series of products are plug and play, no need to configure, to a large extent, the user installation and commissioning process is simplified.
