Lan connections more than 400 meters apart

[Mukesh Tripathi]

Hey Guys

I want comments on what I am doing (right or wrong). I have connected 10 compurtes to 1 server. 7 of them are near by i.e. 10 - 20 meters apart but remaining 3 computers are 400, 500, 450 meters apart respectevely. This I am doing with 1 switch of 16 ports, 1 hub of 16 ports and another switch of 8 ports. Lan connections are slow but working, am I doing right or there is another way of doing this . Pls tell me !

if the hub is a standard hub, I would dump it for a reapeater what I think is called a active hub, one that amplifies the signal,
400 meters is pushing it a bit, and yes it would be a tad slower.
if you could use a fiber backbone to the ferthest ones it would be much better, but also more expensive too.

are you doing this over a 400m length without repeating the signal?

i believe the un-repeated length cat5 can go is 100m, so like bailey said, you will need an active hub in there every 100m. that would explain why it is going so slow.

A cheap simple switch (not a hub) can be used as a repeater. You need one every 100 meters. The reason you need a switch and not a hub is to preserve full duplex operation.

I am sending data using 10 mbps hub at 10mbps

That's still only half duplex and is a big bottleneck. With that many machines, you need a 100 mbs switched network.
