Abstract
The tradeoffs between noise, distortion and fibre length allowing multichannel TV transmission by analogue modulation over kilometer lengths have been investigated experimentally. Two and four VHF TV channels have been transmitted using linearly driven diode lasers at 0.83 μm and multimode fibres over four and one kilometer, respectively, with signal/noise ratios above 40 dB (video unweighted) and intermodulation distortions below −65 dB.Keywords
