Abstract :
A quasi-feedforward compensation technique is described for linearization of LED´s in analog fiber optics based video transmission systems, Experimentally we have observed an improvement of more than 35 dB in second-order and 20 dB in third-order distortion in a system transmitting three TV channels simultaneously. The linearized system is capable of video signal transmission over a distance of at least 2 km without repeaters.
