1. A cable network system comprising:
a master terminal center (MTC) comprising:
a first optical communications module link extender (OCML) system, the first OCML system comprising:
a first dense wave division multiplexer (DWDM) that is configured to receive one or more first optical data signals at a first input of the first OCML system, combine the one or more first optical data signals, and output a second optical data signal;
a first wave division multiplexer (WDM) that is configured to receive the second optical data signal from the first DWDM and one or more passive optical network (PON) signals from a second input of the first OCML system, and is further configured to output a third optical data signal;
a first coherent transport platform and a second coherent transport platform, wherein the first OCML system is further configured to receive a first coherent data signal from the first coherent transport platform, wherein a second OCML system is configured to receive a second coherent data signal from the second coherent transport platform, wherein the first coherent transport platform and the second coherent transport platform are configured to receive the first coherent data signal and the second coherent data signal from a device at the MTC; and
a secondary transport center (STC) located downstream in the cable network system from the MTC and comprising a third OCML system; and
an outside plant located downstream in the cable network system from the STC and comprising a
multiplexer-demultiplexer (MDM) that is configured to receive a fourth optical data signal from the third OCML system.
