GBOX: GBX-F-HDMI-VGA – Fiber Extender – 4K UHD

EMCORE’s new GBOX Series provides multimedia transport of video over Fiber, CATx/HDBaseT and IP with H.264 encoding / decoding, along with audio, data, and remote KVM functionality, up to 3840×2160/30Hz. GBOX transmitters and receivers can be used as point-to-point fiber links or can be connected through our new Genesis XD Matrix Switch, an all-in-one converting, switching, routing and distribution solution for point-to-multipoint applications.

The first of the GBOX series, GBX-F-HDMI-VGA, shown here, is a single fiber extender that supports two auto-detecting video interfaces: HDMI 1.4b for digital video sources with Audio Return Channel (ARC), Ethernet and CEC, as well as VGA & Component video for legacy analog sources. The GBX-F-HDMI-VGA offers separate stereo analog, 10/100 Ethernet, bi-rectional RS-232, CEC and IR support. The fiber SFP+ port handles up to 10 Gbps over multimode fiber up to 300 meters, or singlemode fiber up to 10 km. Transmitter and receiver units are sold separately, and an external power supply is included.

The GBOX Series are rugged tabletop or wall-mountable units designed for connectivity and support for any short or long distance 4K UHD multimedia or KVM application and, when connected through the Genesis XD, virtually unlimited topologies are possible.
