Connect a hub to a transceiver using a transceiver cable, and the hub can be connected to multiple nodes. This system is shown below.
When you want to connect a node to a hub, use twisted pair cable

If distance between the nodes is not too great, you can connect a twisted pair cable to a hub directly, without using a coaxial cable or transceiver.
