The new Gefen ELR (Extra Long Range) extender for HDMI over one CAT-5 with PoL (Power over Line) provides a point-to-point transmission of 4K and Ultra HD content with RS232 and bi-directional IR. PoL provides power to the receiver unit using the same single Cat5 cable, thus there is no need for an external power supply at the receiver side. Distances up to 150 meters (490 ft.) at 1080p full HD and up to 100 meters (330 ft.) at 4k and Ultra HD are specified, and Gefen says this is HDBaseT capable.
In addition, Gefen says it will launch a fiber transmitter that delivers 4K (3840×2160@30Hz) together with RS232 and bi-directional IR using one SC-terminated fiber optic cable. Claiming a 2,000-meter (6,600-foot.) distance, details on what fiber system the new extender will use were not available at press time. But, we’ll report on it at the Digital Signage Expo (DSE) this week.
