Viscore Technologies Blog The Emergence of CWDM PON

The TDM-PON technology is not an effective solution to support over 100M bit rate FTTx access. DWDM PON could do that but it is not mature, probably not cost effective either. A Hybrid solution of CWDM-TDM-PON may be the best solution, and support up to 1x256 splitting ratio, while still offer up to 155M bit rate to premises sites.
