Long Range Ethernet 5

[phoneguyjr]

I am needing to connect 2 remote locations less than 2 miles away from a central point and I am just wanting to know what some of the LRE's that other techs have used and trust to work. One thing that we have to worry about it how well it puts up with lightning. We do have porta-systems on the far ends and and a good Termination box in the near end with lightning protection but we get a lot of lightning up at this site. Is there anything that seems to hold up better than others as far as that goes. We are only running a couple of computers at each location. Fiber would be ideal but cost of it is limiting us down to LRE. Any help would be appreciated. Thanks. Matt

Fiber. Will run for two miles and is not conductive.

Carlsberg don't run I.T. departments, but if they did they'd probably be more fun.

I know that Fiber is the best solution, but as I said in the first post, the customer does not have the funds to do fiber and the only other option is LRE. Please don't post the general knowledge replies that I already addressed in my main post. Thanks, Matt

I apologise, I missed that. The only other solution I can think of is radio/wireless. They can (I believe) travel much further than two miles, providing you have powerful directional equipment. The speed wouldn't be amazing, but I can't think of anything else that would cover the distance.

I've never prices up directional radio gear, but your usual supplier might be able to give you some ideas?

Radio/wireless is not an option either, there is not anywhere close to line of site, this is on a mountain with big hills in between sites. We do have copper installed and working the phones at the site, and burying fiber is going to be really hard to do, as well as expensive. The customer will eventually do fiber but as of right now, they do not have the funds. We are looking for a short term thing that will probably end up lasting for a few years. I am just wanting to know some reliable LRE devices. I have had experience with the cisco 2950 lre units, but they are now discontinued. Thanks, matt

I thought that LRE could only cover 4-5000 feet?

Matt you could use point to point circuits for this from your telephone service provider. We use T-1's between our remote clinics and the main campus. I am pretty sure at one point we used the 56kbps circuits and then upgraded.

One other thing and I know you covered it. I have a building coming up in the back and I am running 100 pair copper and 2 fibers to it. The cost of copper is ridiculous now days. I looked at the estimates for you and the fiber is costing me a few cents per foot less than the copper.

Other than these two options, I don't know of anything that would be stable. Maybe a couple of cable modems from your local ISP and VPN client?

Short Haul modem?

Local DSL or cable modem service and a VPN?

Since you only have a few computers at the far location if you have 1 twisted copper pair, or get a dry pair from your telco as a "LADA" ckt , you can use an ethernet range extender, some will work up to 5 miles, see one source below, but there are others also!

No Line of Sight rules out all the high speed choices (FSO, Proxim Tsunami, Cisco Aironet, etc.)

TutSystems has VDSL routers that can go 25,000 ft. While they advertise 70 Mbps, by the time you want 2 miles, 5 Mbps may be more realistic.

Still, it should beat VPNs over Cable Modems atteched to the internet, your next best choice. (Linksys RV042 is a good choice)

I tried to remain child-like, all I acheived was childish.

11.4 MBps over 2 twisted pairs up to 23K feet is probably as good as it gets over twisted pairs at 2 miles.

We have used the Patton units as well, and they work great for a couple computers on a connection.

Thank you all for the replies, I have looked at the patton 2157's and that sounds like a good way to go. How is the reliability on those? As far as getting point to point, this location is still on the campus, so the local provider wont go to the remote location. But I think that we will get this figured out. Again, thank you. Matt

phoneguyjr..oneac make great ligthning protection that will
work great in your case porta-systems don't last if you
have alot of storms i am south carolina and i use the oneac
and don't have any damage to my phone systems like i use to
with other protection.oneac makes a yellow five pin module
for digital phones and a blue five pin module for analog
phones as well they make protection for t1 circuits.

hope this helps
