Systems and methods for providing a wavelength independent passive optical network extender

A method for operating a passive optical network extender, comprising:

• receiving, by the passive optical network extender, a first optical signal from a remote node device of a passive optical network via a first optical link wherein the first optical signal comprises wavelengths in the O-band, L-band, and/or C-band;
• amplifying the O-band of the first optical signal using a first Raman amplifier of the passive optical network extender to obtain a first Raman amplified optical signal;
• separating the O-band of the first Raman amplified optical signal from the L-band and/or the C-band of the first Raman amplified optical signal;
• amplifying the O-band of the first Raman amplified optical signal using a first optical amplifier of the passive optical network extender to obtain a first amplified uplink signal, wherein the first optical amplifier is a semiconductor optical amplifier (SOA) or a bismuth-doped fiber amplifier (BDFA);
• amplifying the L-band and/or the C-band of the first Raman amplified optical signal using a second optical amplifier of the passive optical network extender to obtain a second amplified uplink signal, wherein the second optical amplifier is an Erbium-doped fiber amplifier (EDFA);
• and
• passing the amplified first and second uplink signals to an optical line terminal via a second optical link, wherein the optical line terminal is disposed locally at a hub site along with the passive optical network extender.
