Abstract :
Effects of optical reflection on transmission characteristics with conventional fibre (1.3 μm zero dispersion) are examined using 1.55 μm conventional and λ/4-shifted DFB lasers. It is shown for the first time that λ/4-shifted DFB lasers are superior to conventional ones in transmission performance with optical reflection. BER floor levels of λ/4-shifted DFB lasers are lower than those of conventional ones, and do not change for the reflection level of PC-type optical connector
