I agree. I'd invest in quality primary protection and then use the secondary devices that were mentioned previously. You would certainly be hard-pressed to run anything new other than wireless, so stick with what you have.

Looks like a candidate for Mike's point to point if you cant protect the wiring

I'm back again. I got a quote on installing "protected entrance terminals" to protect what turns out to be a 25 pair cable buried between the buildings. I derived from the quote that the devices I've been quoted can be found at the web site www.circatelecom.com. Does this look like the "primary protection" solution advised above? I also did a bit of research on a wireless bridge. I determined that the buildings are 103 feet apart. The equipment I'm looking at can be found at https://www.gnswireless.com/GNS1150.htm
The wireless kit is certainly a lot cheaper than the PET's, but would I not have a potential lightning issue from outdoor mounted wireless antennas?

Oh really?

Sticking anything in the air requires proper grounding.

The cell phone towers have the biggest ground fields of 20 9ft ground rods all cad welded together to protect the investment.

You may never get hit

I believe the statement was "would I NOT have a potential lightning issue from outdoor mounted wireless antennas"?

As in "wouldn't I have a problem with lightning"?

The answer is yes but far less likely than with the copper in the ground. It would have to hit the building to hit the antennas if they are attached to say the side of the building. Even on a short pole your odds are less.

Well it sounds like a numbers game and, as always, businesses these days go with the cheaper route.

Anyhow, take a look at this product, 3C250T4 from 3com. I have seen these on Ebay as throw away items; new around 100 bucks. Since you say there is only 100' between the building these may work with one caveat; your 25 pair is C-3 (though i wouldn't be surprised if they worked on C-nothing).

Basically buy 4 of these and throw them away as they get toasted over the years. Plus you'll have the hard wire benefit of 100mbps, half duplex, throughput.

If the existing cable is also used for telephones, then you really need to have the protectors installed regardless of your decision to use wireless. By code the protection must be there, and for good reason, life-safety.

Look I am not a big advocate of customers going to ebay and trying this stuff on there own. NFC is correct and you will need the protection anyway. I think it would be prudent to have which ever company is the lowest priced, best qualified vendor to do the job come in and make it happen.

Unless you understand grounding and bonding you really are not prepaired to tackle this adventure.

As for the throw away switches, that is not lightning protection. I have witnessed lightning pass right on through a switch and take out a rather expensive server stack.

Looking at the picture, wouldn't it be easy to string Cat5e aerial across the lot from the utility pole in the center to each building? Or would that require an act of congress to be able to attach to the pole? Aerial I would think is cheaper to run then buried, and the primary protection is the same.

Just throwing ideas out there.
