Hybrid WDM/TDMA-PON Using Self-Homodyne and Differential Coding

A hybrid wavelength-division-multiplexing/ time-division multiple access-passive optical network system using self-homodyne scheme and differential coding was proposed. The laser seed light injected reflective semiconductor optical amplifier was used as the colorless transmitter. It was shown that the proposed scheme can increase the power loss budget of optical distribution network significantly by complete suppression of the reflection noise.
