Greetings,
At first, I want to clear one thing that I am not experts in routing & switching, so I happen to ask any stupid question please let me off.
We are planning to implement Fiber Optical backbone LAN for our DMZ (for 6-7 Servers) which will be connected to Gigabyte Switch terminating to all other switches connecting to the 125+ client PCs. Like the way……..ISP—-à Router—à Firewall——à Fiber Optical Backbone——à Giga Switches——-à LAN Switches.
I have been suggested to buy Cisco Catalyst 3750G-24PS-E.
Please give us the suggestion for as per the following queries:-
1.Does any Fiber Optical Ports come with any Cisco switch?
2.Is it possible to terminate one part of the Fiber optic cable from Cisco Fiber Optical Port (If comes) to other Cisco Fiber Optical switch or Fiber Optical Network Card (installed to any server)
3.Which Gigabyte port Switch you recommend?
4.If I select Cisco Catalyst 3750G-12S for the fiber optic DMZ, what type of interface can be used for Fiber optical like.. SC/ST/LC & what these means exactly?
5. What is the mean of SX or LX SFP’s in LC options?
6.What is this SFP? Are these the same the fiber network cards used in PCs or can only be used in Switches& what is the use of it regarding the switch?
7.What does the mean of 32-Gbps, high-speed stacking bus?
8.What is Innovative stacking technology?
9.Enhanced Multilayer Image Software (EMI) installed Meaning………what?
10.If I use L3 Switch then also do I require router in my edge network?
General info of our network:
•Will be using 6-7 windows servers
•Will be around 150 Users
•SQL, Tally, Office Applications etc. will be used over the network
I would rather request you to suggest us the best router & switches for implementation of the above mentioned setup.
I know what all stupid questions I asked, even I could also google it to have answer but butter to lean in dept from you experts,,,,, sorry for that.
Many thanks to all of you.
Awaiting for your valuable answers.
Best regards,

So you are in charge of setting up a fibre backbone for a corporate network and are asking on Yahoo Answers for how to do your job ?
Maybe your best option would be to subcontract the install and setup to a professional that KNOWS what they are doing!
i know the answer to most of these questions.
the best answer i can give to you, is go seek a professional. If your business depends on this, go find someone more dependable than YA!.
3750 is a great switch. It only comes with 4 connector ports. You have to buy the cards separate from the switch, it depends on what card you buy to which connector comes on it. You can get sc, st, lc fiber ports, which are all different fiber end connectors, some are multi-mode, some are single-mode fiber.
the rest you will have to go seek a professional.
You question is really a lot like "It’s my job to build a suspension bridge for vehicle traffic. I have some questions: 1) What kind of steel should I use? 2) Are trusses needed? How many do you need? 3) What do the cables do?"
Honestly, you need to hire an expert consultant who knows these things. The answers you get here will just make you more likely to think you know what you’re doing. You could wind up wasting a lot of money buying hardware you don’t even need. (Do you even need fiber? What’s wrong with gigabit over copper, which is about 1/10 the price?)
