Brightlink's New HDMI / HDBaseT 228ft Extender over Cat5e/6 cable with Full HD uncompressed 1080p / 4K signal allows you to Extended your HDMI signal over long distances that standard HDMI cables don’t normally handle. Even over these long distances these extenders keep your HDMI signal free from attenuation giving you crisp clear images just as a short HDMI cable would do. Using an advance HDBaseT chipset inside this Brightlink HDBaseT Extender over single Cat6 cable can reach distances up to 228ft at 1080p, and 130ft at 4Kx2K.

The Wide Band band (38K-56KHz) Bi-Directional IR allows you to either control your display from your source or your source from your display. The IR signal is passed through the Cat5e/6 cable using the IR-TX (transmitter) cable and IR-RX (receiver) cable. The Wide Band frequency of 38K-56KHz makes these compatible with almost all IR remotes. The POC/POE features allows you to power the Receiver from the Transmitter through the cat5e/6 cable so now power supply is needed by the display.
