repeater, even though it has a repeater at each end.)

 

 

[2] 10BASE-T system

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 (10BASE-T).

:Twisted pair cable (10BASE-T)

Basic connections in a 10BASE-T system

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.
