Bismuth oxide-based erbium-doped fiber amplifiers for DWDM-TDM passive optical networks

We propose a long-reach hybrid DWDM-TDM PON architecture in which the proposed amplifier can be effectively used. The feasibility of using the proposed amplifier for long-reach hybrid DWDM-TDM PONs is experimentally investigated by performing a series of signal transmission experiments with an exemplary PON configuration having a total reach of 75 km and 8 split users.
