1. A transceiver for an optical network, comprising:
a first child laser;
a child modulator configured to injection lock the first child laser to a parent frequency of a single mode of a laser source signal; and
an input portion configured to (i) receive a first optical modulated signal on a first coherent tone of the laser source signal; (ii) receive a first optical unmodulated signal on a second coherent tone of the laser source signal, and (iii) route the first optical unmodulated signal on the second coherent tone to the child modulator,
wherein a frequency of the second coherent tone is held constant to a frequency of the first coherent tone,
wherein the child modulator is further configured to output a second optical modulated signal on the second coherent tone.
