Overview
FT-20KM-106 1-Video 2-Data 2-Audio Bi-Directional Fiber Video Multiplexer (20 km)
The FT-20KM-106 is a single-mode fiber video multiplexer combining 1 bi-directional video channel, 2 bi-directional data channels and 2 bi-directional audio channels over one fiber up to 20 km. Shipped as a transmitter/receiver pair, it sends uncompressed 8-bit composite video at 1310/1550 nm with a 12 dB optical power budget. Video interfaces are 75 ohm BNC supporting PAL, NTSC and SECAM at 6.5 MHz and better than 67 dB SNR. Data channels handle RS485 (2- or 4-wire), RS232/422 and contact closure from DC to 115.2 Kbps at 10E-9 bit error rate, while audio gives 600 ohm balanced/unbalanced operation at 6 dBm with SNR above 80 dB. The standalone design operates from -45 to +75 C with LED status indication.
