2 x POTS RJ11 Telephone and Gigabit Ethernet Over Fiber Converter - Multiplexer - Extender Set of FXS FXO Units - Universal Single and Multimode - 1 km MM (0.6 mi) 20km SM (11.4 mi) - Voice Over Fiber

Garage/shop is 300+ feet from house. All phone and DSL enter at the shop. I had taken another lightning strike that took out one phone, one network switch and house alarm module. It was the second strike. No more.Ran some single mode glass between the house and the shop and now have both phone and 1g network at the house. I tried doing the whole IP phone ATAs and setting up SIP, to get phone over IP. What a waste of time.If you need to send phone and 1 gig network a long way, this IS the solutions. Don't waste your time on anything else!

These devices worked great. They were just plug and play. I hooked everything up and there were no complications. Im even going through a PBX system at the end point. I will be buying an extra set just to have on hand, incase these get hit by lightning or something.

Worked just like it says
