Paper Abstract

The implementation of an analog video optical fibre link is a more difficult problem than a digital system. The signal-to-noise ratio (SNR) requirement is more stringent (40 to 60 dB as against typically 20 dB for a digital system), and account must be taken of other significant requirements such as differential gain distortion, amplitude flatness, and group delay. Close attention must be paid to equalizer design and modulation linearity. The performance that can be achieved with analog TV optical fibre links is examined in the light of current and anticipated near-term capabilities of optical sources, fibres and detectors, including light emitting diodes and semiconductor lasers, and step-and graded-index fibres. Both baseband and subcarrier FM modulation are analyzed, and the corresponding attenuation, dispersion, and distortion limits discussed. The analysis is extended to multihop links, and consideration given to choosing an optimum (rather than a maximum achievable) amplifier spacing.
