I have an issue were I need to interconnect 2 switches together. We've estimated that they are 1400 meters away (cabling distance).

I wanted to use a media converter to extend the signal on OS1 fiber, but I can't because I must pay a lot of monthly taxes in order to use the fiber in those premises.

What are my options to interconnect the 2 switches with only copper?

    How about wireless with directional antennas? – Dan Mar 11 '15 at 13:01

    You have to pay monthly taxes if you run your own fiber cable instead of copper? Just curious why they would care if you run a single fiber cable vs. copper? – TheCleaner Mar 11 '15 at 13:09
  • It's an exotic place were an authority put taxes on everything. Also, I can't have my own fiber, it will be their property and I will pay for use. And it seems that they're not really interested by copper, unlike fiber. They still charge us for copper runs though, but it's not expensive. – Narus Mar 11 '15 at 14:32
  • realistically, how much bandwidth do you need to push across this link? – Mike Pennington Mar 18 '15 at 16:12
  • 20mbps symmetrical is more than enough. After some days of research, it appears that I actually have to reach multiples switchs. So, I found that I should use an EFM device associated to multiples CPE with G.SHDSL.bis technology over bonded cooper pairs (2BASE-TL). But I'm not familiar at all with DSL technology. I feel like an ISP :) – Narus Mar 19 '15 at 16:31

You're looking for a device called an Ethernet extender/repeater.

The linked page is not an endorsement, so much as a matter of convenience, since this is the company I'm working with to do something similar for my employer. You should have no trouble finding a multitude of vendors and devices to extend the range of an Ethernet signal, and there's really no interoperability/compatibility issues here. The device just receives an electrical signal on one end, and retransmits it on the other - it's a signal amplifier, made specifically for Ethernet networking.
