Video and data/audio system
Series 200I, 300I and 400I are frequency-modulated fiber-optic video and duplex data/ audio transmission systems that operate on one fiber. Multimode versions use 850/1300-nm light-emitting diodes; singlemode versions use 1310/1550-nm lasers. The systems support 7-MH¥video bandwidth and feature a signal/noise ratio of greater than 60 dB at 25 km. They have a 26- to 36-dB optical budget (to 80 km) and 26-dB optical dynamic range.
