BZBGear BG-EXH-8KF 8K HDMI 2.1 Fiber Extender
Where copper runs out, the EXH-8KF continues on multimode fiber: 40 m on OM2, 200 m on OM3 and 300 m on OM4, carrying 8K at 60 Hz 4:2:0 12-bit, 4K at 120 Hz 4:4:4 12-bit or 1080p at 240 Hz on a 48 Gbps FRL link.
The receiver has two HDMI outputs, so a display and a recorder can both be fed at the far end, plus a 3.5 mm audio breakout. EDID management, bi-directional IR and RS-232 are included, and the LC fiber connector means standard structured cabling can be used rather than a proprietary hybrid.
