| Summary: | 碩士 === 國立中央大學 === 光電(科學)研究所 === 84 === Some effects occur when optical signal transmitted in fiber
link of AM-CATV system,such as Rayleigh backscattering、SBS、
dispersion,etc. These effects have considerable influence on
vedio quality. We measure and analyze the system performance,
including CNR、CSO、CTB, to find the determinant effect for
current commercial CATV system using 1310nm & 1550nm externally
modulated transmitter and give a total comment .
