I'm in a purchase project of a new Gigabit switch for my company.
Currently my company has a "Catalyst 3560G-48TS". It has four additional ports called SFP that I supposed can be used to connect to another switch to constitute a sort of "backbone", right? I want to connect the current switch to the new one with as much transfer rate as possible. Ideally at least 5Gbps (yeah, if I use a single 1gbps cable, it's certainly not enough). Both switches will be separated at a distance of about 15m.
I know nothing about this SFP. Could someone tell me what are supported or supporting this? What cables should I buy? Optical fibers? What's the transfer rate could I expect from EACH SFP port?
Of course, I'm more interested to not so expensive solution, or at least a good quality/price ratio solution.
Thanks in advance.
