4K Ultra HD Extender over One Fiber w/ RS-232 and 2-way IR


Extend HDMI with Ultra HD 4K x 2K support, RS-232, and Bi-Directional IR over one fiber optic cable up to 3300 feet (1000 meters)

The Gefen EXT-HDRS2IR-4K2K-1FO 4K Ultra HD Extender for HDMI over One Fiber is a complete solution, allowing HDMI, RS-232 and Bi-Directional IR to be extended up to 3300 feet (1000 meters) at 4K resolution and up to 6600 feet (2000 meters) at 1080p60 Full HD. This HDCP-compliant extender is the ideal for installations where the HDMI source and display are located apart from each other in an interference-prone operating environment. A single strand of SC-terminated multi-mode fiber optic cable is used for extension, providing excellent protection from electromagnetic interference (EMI), and preserving signal integrity. The Automatic Virtual EDID feature allows automatic copying of the Extended Display Identification Data (EDID) to the sender unit for continuous availability to the source. This allows rapid recovery of picture upon display power up or when used in conjunction with Switchers and Matrixes. Compared to similar copper-based solutions, optical signal transmission provides inherent galvanic isolation and excellent immunity to electromagnetic interference. These Sender and Receiver modules also feature metal enclosures, providing further protection against radiated noise. Locking HDMI and power connectors ensure trouble-free installation and long-lasting, reliable operation.

Video Support
Resolutions supported include 4K Ultra HD (3840 x 2160 @ 60Hz 4:2:0) and 4K Cinema (DCI) (4096 x 2160 @ 24 or 30Hz 4:4:4), 1080p Full HD, and 1920x1200 (WUXGA). This HDCP compliant extender also supports Deep Color and 3D signal.

Audio Support
Multichannel digital audio including 7.1 channels of LPCM and HBR (High Bit Rate) lossless formats are passed through.
