Overview
FT-20KM-101 1-Channel Bi-Directional Video, Data and Audio Fiber Optic Multiplexer (20 km)
The FT-20KM-101 is a single-mode fiber optic video multiplexer carrying 1 bi-directional video channel, 1 data channel and 1 audio channel over one fiber up to 20 km. Supplied as a transmitter/receiver pair, it uses 8-bit uncompressed transmission at 1310/1550 nm with a 12 dB optical power budget. Video supports PAL, NTSC and SECAM over 75 ohm BNC at 6.5 MHz bandwidth, with video SNR above 67 dB and differential gain and phase below 1.5%. Data supports RS485 (2- or 4-wire), RS232/422 and contact closure up to 115.2 Kbps; audio runs at 600 ohm with SNR above 80 dB. The standalone unit operates from -45 to +75 C, gives LED status and is immune to EMI, RFI and ground loops.
