How far can you run with an Ethernet cable?

Network cables are awesome, but they’re not perfect. There’s a limitation on how long those skinny little wires are going to hold on, even if you pay for the best possible ones. Traditionally, that limit is listed at 100 meters (393 feet) but that number can be lower depending on several factors such as the way the cable is made and the electric fields the cable needs to pass through. What can you do beyond that?

If you choose to stay with a wired solution, you can go to Ethernet over Fiber (100-Base-FX). This solution lets you replace the regular “category” cables with fiber for long runs. The maximum recommended run is 400 meters (about 1,600 feet) so if run the longest possible “category” cable followed by the longest possible fiber strand and the longest possible “category” cable on the other side, that gives you the ability to go 600 meters, about 2,400 feet. That should be enough in most cases. Solid Signal has a wide selection of 100BaseFX products that make it easy to connect your wired network over long distances.

If you need to go further, you can use something like Ubiquiti’s LOCOM5 Nanostations that make it easy to connect two points up to 15,000 meters (over 9 miles) away as long as they can see each other. They’re a super-inexpensive way to replace Ethernet cables over long runs and it makes it easy to connect two buildings over reasonable distances without having to bury wires.

I can hear you saying, “If wireless is so easy and cheap, why would anyone use wired?” Good question. Wired technology came first, and as such it was more expensive from the get-go. More importantly, though, fiber is secure. It can be buried and the transceivers that connect from copper to fiber can be put in locked closets. This doesn’t mean it’s completely hackproof but it’s a lot harder to break into a wired signal than a wireless one. If absolute security is your bag, you need to use fiber.

Either way, though, the limitations of plain copper Ethernet cables shouldn’t concern you, because Solid Signal has easy ways to extend your network as far as you need it to go!
