1. An optical communication module link extender (OCML) system comprising:
a multiplexer at a headend and configured to receive a first Passive Optical Network (PON) signal in a downstream direction and output the first PON signal;
a first dense wave division multiplexer (DWDM) at the headend and configured to receive a first Ethernet signal in the downstream direction and output the first Ethernet signal to a dispersion correction module (DCM);
an optical switch at the headend; and
a first wavelength-division multiplexer (WDM) at the headend and configured to receive the first PON signal and the first Ethernet signal, combine the first PON signal and the first Ethernet signal, and output a combined downstream signal to the optical switch, and further configured to receive, from the optical switch, a combined upstream signal including a second Ethernet signal and a second PON signal, and output the combined upstream signal in an upstream direction.
