Claim 11:
12. A method of registering a first upstream coherent optical transceiver of a plurality of upstream coherent optical transceivers, the method performed by a downstream coherent optical transceiver in operable communication with the plurality of upstream coherent optical transceivers over an optical transport medium in a coherent passive optical network (PON), the downstream optical transceiver including (i) a receiver portion, (ii) a local oscillator (LO) providing an LO signal to the receiver portion, and (iii) a power control module for controlling a power level of the LO signal, the method comprising steps of:
transmitting a discovery message to the plurality of upstream coherent optical transceivers;
receiving, in response to the step of transmitting, an upstream power level of the first upstream coherent optical transceiver; and
dynamically controlling the LO power level according to the upstream power level received from the first upstream coherent transceiver.
