Claim 18:
19. A method comprising:
providing a first optical signal from an optical power supply to a first network element;
providing a second optical signal from the optical power supply to a second network element;
at the first network element, using the first optical signal to synchronize a first local oscillator; and
at the second network element, using the second optical signal to synchronize a second local oscillator;
operating the first and second remote radio heads in synchronization;
wherein each of the first optical signal and the second optical signal comprises a sequence of optical frame templates with control information imprinted onto light of at least some of the optical frame templates;
wherein each of the optical frame templates comprises a respective frame header, and a respective frame body;
wherein each frame body comprises a respective optical pulse train;
wherein the sequence of optical frame templates has a first time duration;
wherein each of the respective frame headers has a second time duration;
wherein each of the respective frame bodies has a third time duration, a sum of the second and third time durations being smaller than or equal to the first time duration;
wherein each of the respective optical pulse trains has a period of a fourth time duration that is smaller than a smaller one of the second and third time durations;
wherein the third time duration is at least 10 times longer than the fourth time duration;
wherein the second time duration is at most 10% of the third time duration; and
wherein the first time duration is at least 10 times longer than the third time duration.
