FAST ETHERNET CABLE LENGTH
FAST ETHERNET CABLE LENGTH
(OP)
Hi,
I'm currently using 10Mbit components for my industrial ethernet connections. For this solution I know the cable length limitation. I know hw to cascade Hubs.
But how does this work with 100Mbit ethernet? Can I cascade the segments of the network when I use switches instead of hubs? (Cascading of Hubs will not work, because of the collission detection.)
With cascading I mean extending the network with the hubs not placing all together in one place, but 100m away from each other.
Please help me!

I take it were are talking CAT5 UTP when your talking of the connections ?
If so then even for 100 Mbps the max length is 100M to the nearest Hub. The maximum distance between two hubs is only 5 meters. And you're supposed to have only two hubs between stations. That means a maximum of 205 meters between stations with two hubs in between.
One thing you must make sure with your network at 100Mbps is that all the NIC and Hubs run at 100 Mbps otherwise the network will drop to the slow speed of 10 Mbps.
If you need to extend the range furthur you could use a switch which could connect two hubs together. This will resolve the collisions and extend the range by 200 m.
If your using fiber instead of UTP then of course the range is longer (and the price more expensive) as the distance
between hubs is about 400m.
Any help ?, yes no let me know.

It all depends on the what the fibers are conected to rather than the fibre optics themselves.
You get fiber optic systems running at 10 Mbps (as in 10Base-FL) or at 100Mbps (as in 100Base-FX).
Also like regular cable there are different grades of fibre optic cable and different ways to send the data down it such as Voice Grade fibre or muti mode transmission.
So the answer in summary is, It Depends !

It even includes details for switches instead of repeaters (switch = DTE in that context)
