Extending network over a dry pair

Wed Dec 12 23:05:00 UTC 2018

Actellis also makes some ethernet over dry pair gear.  The only issue is that they require repeaters like a T1 (different spacing though).  I'm guessing if you're doing T1 at that distance you already have repeater housings in the field at least.

Six miles is probably pushing it, but Proscend make some interesting Long-Range Ethernet SFP transciever which are VDSL based. They're horrendously documented and they draw *way* more power than the SFP specification allows.
They also make a version which is design to terminate VDSL broadband circuits - A couple of those found their way to my desk recently and it turns out that despite the horrendous documentation and sightly scary heat output (they come with a little paper note in the box which says something along the lines of "WARNING! MODULE GETS HOT - DO NOT TOUCH DURING OPERATION."), they do generally Just Work!

A quick question for you guys; 
If you had a single dry pair (pair of copper wires originally for phones) to a remote site that was around 6 miles away, what would you use? We currently are just extending a T1 line to this site, but 1.5Mbps isn't cutting it anymore. Unfortunately it's a research site on a federally protected wildlife preserve so we can't run any new infrastructure (fiber etc) and it isn't in a geographical place where point to point wireless is practical. We were thinking there is some sort of network extender that uses some form of DSL for higher bandwidth capacity. 
Any suggestions?
