Abstract
An optical communication system comprises an optical communication device and an optical power supply configured to generate a sequence of optical frame templates directed to the optical communication device. The optical communication device may use the received optical frame templates as a light source for generating data-loaded optical frames and/or may extract from the optical frame templates control information encoded therein using one or more headers thereof.
Claims20
An apparatus comprising:
- an optical pulse source configured to generate an optical pulse train at a pulse-repetition rate;
- a first optical interface connectable to receive the optical pulse train;
- an optical splitter connected to the first optical interface;
- an optical modulator connected to a first output of the optical splitter and configured to modulate data onto the optical pulse train at a symbol rate equal to the pulse-repetition rate;
- and
- a first optical receiver connected to a second output of the optical splitter and configured to extract the pulse-repetition rate from the optical pulse train.
