Analogue baseband TV transmission experiments using semiconductor laser diodes

Abstract

The transmission characteristics of analogue video signals are investigated by using semiconductor laser diodes. It is shown that the linearity degradation due to speckle noise depends on the optical-fibre types adopted. Based on this investigation, transmission over 32 km is carried out by using a 1·3 μm laser diode and single-mode fibres, with 46 dB unweighted s.n.r.
