Well, you didn’t actually rate my previous answer. There’s nothing that you can diagram with any more detail to show how it really works.
You must have a:
– minimum 0.5 m between T-connectors
– maximum 185 m cable length
– maximum of 30 nodes (i.e. connections)
An cable can be extended by installing Repeaters, which amplify the signal…
A Repeater counts on each segment as a node and can be connected at ANY location in the Thin-Ethernet cable…
However, if a network needs more than 2 repeaters…
the following limitations apply:
When an Ethernet signal travels from its source to destination station, it can travel through:
– maximum of 5 segments
– maximum of 4 Repeaters/hubs
– maximum of 3 populated segments
(Populated segments have more than 2 nodes connected, un-populated segments have only a node at each end, so a 10baseT-segments is a non-populated segment).
And for this discussion, a 10BaseT-Hub is like a repeater and a 10baseT cable can be treated as a cable 10base2-cable with just 2 systems on it.
There can be more repeaters/hubs in the complete network, and an Ethernet signal can pass-by more than 4 Repeaters/hubs, as long it does not have to go THROUGH more than 4 Repeaters/hubs.
If these rules are violated, the network becomes unreliable.
