We regularly use Coax in house for testing purposes. The 10Base-T transceivers had to connect to the AEH and OS via the normal drop cables but the transceiver plugged directly into the AC450. One advantage of using twisted pair is that the hub shows you the activity on each port and can show you the total network load. With Coax (10base2) the segment lengths are limited to 185m (500m with Thickwire - 10base5) with no more than 30 transceivers per segment with a minimum separation of 0.5m. With Twisted Pair (10base-T) each device is connected to a hub with a cable of max length 100m. There can be no more than 4 hubs between any 2 devices. The hubs can interconnect with up 100m of twisted pair but you can also get fibre optic interfaces for hubs and connect hubs with up to 2000m of fibre optic. The standard says that the maximum distance between any 2 devices is 2500m but this is just "playing safe". The theoretical maximum distance is about 4500m but due to propagation delays at every transceiver and hub connection the actual maximum is less than this. For ethernet to work signals must be able to travel between the 2 furthest apart devices in the network in 25.6 microseconds, hence the distance limit. However, the rules only apply when using standard hubs. If Ethernet Switches or Bridges are used then the network either side of the switch/bridge are considered separate networks for the purposes of counting hubs between devices and distance between devices. Note that you can get Switches which will connect with fibre optic over distances much greater than 5000m (not using standard ethernet protocol). Note that if you have a lot of devices within 100m you can get stackable hubs, for the purposes of "the rules" this is just one hub. E.G. You could have six 24port hubs in a stack to create a 144 port hub!

Has anybody used a twisted pair cable for MB300 instead of thick ethernet coaxial cable? If so what are the precautions and additional hardware component to be considered. Is there any possibility of using thin ethernet coaxial cables for MB300? We normally use thick ehternet coaxial cables.
