can fiber transceiver three connection modes, namely \"point to point\
Point-to-point connection, which is also the most basic connection mode of can fiber transceiver. In a point-to-point connection mode, we only need two can fiber transceivers with one fiber interface.
Hand-in-hand connection mode. In this connection mode, we not only need the two can fiber transceivers with one fiber interface in the point-to-point connection project, but also need to connect several other can fiber transceivers with two fiber interfaces in the middle.
In the ring connection mode, we need a specially designed can fiber transceiver with two fiber interfaces, which is different from the dual fiber interface can fiber transceiver in the hand-in-hand mode.
CAN bus is the same as the general network cable is the use of twisted pair to do the bus, but the CAN bus connection is the same as the grape string to be connected to the equipment one by one hung on the twisted pair.
