The Magenta Research CFS-HDMI-TX2 extends 1920 x 1200 uncompressed HDMI or DVI video, audio, and serial signals up to 6,600' (2km) over multi-mode fiber optic cables. The transmitter has a small form factor and can be easily and securely mounted behind a screen or other small areas via the built-in mounting flange. Its range can be extended to up to 2.5 mi (4km) and 18.6 mi (30km) by using optional single-mode fiber optic modules (sold separately).
While it ships with one MMF SFP standard module, the CFS-HDMI-TX2 Transmitter features a second port that, when populated with a second SFP (sold separately), introduces a variety of signal distribution options. For example, you could cascade signals to a second transmitter, or feed a second grouping of Voyager receivers (which can be daisy-chained).
