There are many types of applications in businesses as well as homes where IR is used to control equipment. It's very typical for home furnishings, office supplies, ceilings and walls to obstruct an IR emitter for remote control signals. This is when an IR cable comes in handy; to help extend the IR signal in an open area for the remote to properly communicate with emitter. Some IR cables are plenum rated which works well if you need to run your IR cable through ceilings, floors and walls.
