1-Channel Video and 1-Channel Audio Fiber Multiplexer, Single-Mode FC 20km

The FT-922 from F-tone Networks is a single-channel fiber video multiplexer set that transmits one forward video channel together with one simplex forward audio channel over a single-mode fiber up to 20 km. PAL, NTSC and SECAM cameras connect through a 75-ohm BNC input with gold center pin, and audio terminates on a screw terminal block with 24-bit coding and SNR above 80 dB. The optical section uses a standard FC connector, and the link keeps video differential gain below 1.5 percent for stable color reproduction. Rated for -45 to +75 °C with MTBF above 100,000 hours, the set is suited to elevator surveillance, parking lots and commercial sites that need camera video plus one-way audio on a single fiber.
