Hi
I have been asked to setup a system to  connect 3 buildings to a main building using the available fibre (SingleMode Duplex 9/125) Im projecting to use 4 HP 1800-24G switch and a Qlogic 5600Q FC Switch. My problem is how to go from multimode output of the ethernet switch to the single mode. does the qlogic convert? do I need external converter.
Each Ethernet switch will be connected to the Fibre Switch. The Main Building has a Data server and internet connection on which the other 3 must be connected to. not very high data transfer.
Thanks for any suggestion

You probably should design new network first, Cisco sales can help you choose hardware afterwords.....

Or alternative  -  something like this:

Some example VLAN usage you canfind on EE, Cisco web or many others.............

If you have multi-mode fiber outputs and need to connect it to single mode fiber, you really need to get some fiber mode converters first. The rest of the LAN should flow as normal.

You will need fiber into your switch at each building and fiber out going to the next building.

Here's a link:

Pretty spendy fiber converters.

The HP 1800G-24 switch does not have a multimide output.
It has dual-personality ports; which means you can use either the RJ-45 copper ports or Mini-GBICs for fiber.
You'll need to use the aproporiate Mini-GBIC; in your case it's the ProCurve Gigabit-LX-LC Mini-GBIC (J4859C)

Thanks for your help, with your help my questions have been answered. I'll be using 1000BaseT to fibre Media Converter on each side and therefor there is no need for a fibre switch. The cost is almost the same but it is straight forward. I've attached a file of the setup I think is working. I know this is a low cost solution but there is not enough budget to go with cisco switch or other enterprise level switches.

I see you're using IMC for the media converters; good choice.

He'd still have to by SFPs for the switch.

PROSAFE" GBIC MODULE 1000BASE-LX FIBER SFP
http://netgear.com/Products/Switches/SwitchModules/AGM732F.aspx

About $200 apiece

Yes , that true, but there is always ebay, or other can be less 200

Personally I rather spend more for better performance, and most importantly -future expandsibility.
Having remote buildings at 100, and not "backboned" 1gb just seems sad.
If he is knows for sure next 5-10 years will not be more traffic demand, at all good.

Thanks to all of you.
Your suggestions have helped. after further investigation I have opted for an HP solution
-on the main an HP 2810-24G  (it has 4 MiniGbic Ports) with MiniGbic LX-LC
-on the 3 other buildings a HP 1800-24G with MiniGbic LX-LC.

I checked netgear products, but I have no experience with them and my customer wan't HP, as he is allready using HP products in his facility.

I object.

Many answers were provided and all of them good. Just because the asker opted to go with a solution that maybe wasn't mentioned does not validate the asker from requesting this Q be closed.

The asker also stated "Thanks for your help, with your help my questions have been answered." Therefore, the asker should accept the best answer or split points amongst the answers.

Sorry, my opinions and .02 cents.

No worries, not upset at all. There is a learning curve here.

It is just when one has good answers and the Q is requested to be closed without any points to the correct or best answer or to those who helped, that is just not how EE is supposed to work.

Thanks for reviewing!
