1-Channel Video and 2-Channel Forward Audio Fiber Optic Multiplexer, 20 km SM

The FT-20KM-95 from F-tone Networks is a fiber optic multiplexer that carries one channel of uncompressed composite video together with two simplex forward audio channels over a single single-mode fiber, with a reach of up to 20 km on 1310/1550 nm wavelengths and a 12 dB optical power budget. Video is digitized at 8-bit resolution through a 75Ω BNC interface and supports PAL, NTSC and SECAM formats. Both audio channels use 24-bit digital encoding at 600Ω, 6 dBm, with better than 80 dB SNR for clear program or voice audio. The pair works as standalone transmitter and receiver or as cards in a 19-inch rack chassis.
