Connecting two different networks

I have two seperate standard networks (CAT 5 Twisted Pair Cable) running through a switch.  They are separated by a distance of about 500 meters.  The owners wish to connect them.  They mentioned fiber optic cable as a possibility.  What equipment would I need to have to connect the two switches using fiber optic?  using CAT 5?

in case fiber optic
if both switches have utp ports avialable the u need utp to fiberoptic converter and a fiberoptic router to connect the two network switches

for utp(cat 5)
u just need a router to connect

If the two networks are seperate networks, you will need to use a router to connect them,  you can buy a router then get the aui to fiber converters, then plug the switches into the router.

You have 2 options, you can run 250 feet of cat5, and then in the middle have another switch and plug them in to that, or you could run fiber between to two, but they will require fiber transcievers at each end...

I assume that both LAN's will belong to the same
IP segment.

What Provider/Model are your switches?

There are some switches which have expansion slots, so you could add a fiber module on both and connect them, but this is either expensive or impossible, since I don't know if your switches have this expansion slots or if the provider has fiber modules for them.

If you can't afford fiber, then it's a tough one, cuz it's 550 meters. You wouldn't just need to add another switch/router, since that would only get you to 200 meters. (100 from LAN 1 to switch/router, 100 from switch/router to LAN 2), and my guess is you don't want to
put a switch/router every 100 m.  .....=).

If both LAN's have the same IP addressing you don't need a router.

Most modern switches support fiber modules, like Foundry's FastIron series.

If you could get 2 hubs, both supporting 10Base5, you could put a hub at each switch, connect 2 switch ports of each switch to their respective hub, and configure those ports as trunk, and have a coax go from hub to hub. This way you get the 500 meters, but of course this is cheap and slow.

Most of the guys are correct about what they say, except the 250m for the 10base2 that I suppose you use, but the rest is correct.  Do you have wires between the two offices, cause if you do there is one wery easy solution, and that is to use a pair of modems with ethernet ports, they will basically do bridging.  You still have to make both networks part of the same subnet, or you will need a router.  Another very popular solution is to use Wireless bridges/routers, can get them very cheap, and if you have line of sight, you are on the roll.

Hope this helps
