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 ¿m laser diode and single-mode fibres, with 46 dB unweighted s.n.r.
