Colorless optical sources for fiber-optic access networks of new generation

We present recent advances in the development of self-seeded colorless WDM-PON optical links employing modulation averaging. Modulation- averaging, employed as a reflector at the remote node, improves the link margin and allows for a wider range of bias conditions at the transmitter. The modulation-averaging reflector is a passive optical device and therefore the remote nodes in our proposed WDM- PON system remain passive, with no power needed to accomplish this improvement. The suitability of proposed architecture for next-generation optical access is demonstrated by transmission over 60 km at 1.25 GBaud line rate.
