What Is Keystone Jack?
Keystone jacks are the unsung heroes of the data communication and LAN wiring world. They don't get all the glory, but they get all the work done. Without them, we'd be stuck with bare wires hanging from our walls and ceilings, which would look like a hot mess. They're also great for mounting optical connectors into your wall plate or patch panel! Keystone jacks are used in data communication and LAN wiring. The keystone module is a snap-in package to mount low-voltage electrical jacks in a wall plate or patch panel. The keystone jacks are connected to a matching keystone plug, generally mounted in a wall plate or patch panel. Optical connectors can also be mounted into the patch panel or wall plate using the keystone module. In the world of technology, some things don't change. The keystone jack is one of those things. It's called a keystone jack because it looks like an architectural keystone—a stone used to support an arch, just like the standard RJ-11 wall jack used to connect telephones, fax machines, and dial-up systems. Just like those other technologies, there's no need to worry about the future of keystone jacks: they're here to stay! The keystone jack is the unsung hero of all things networking. It's a jack that can do anything and everything you could ever want, in any form, cable type, on any side. The keystone jack was a dream for network engineers and designers: they could build one panel that would hold many different types of jacks and wiring configurations, so they didn't have to spend money on designing separate panels for every new type of jack or cable. The best part? The keystone jack is versatile enough to be mounted on either side!
