Abstract
A first apparatus comprises: a processor configured to generate a first synchronization message; a transmitter coupled to the processor and configured to transmit the first synchronization message to a second apparatus at a first wavelength; and a receiver coupled to the processor and configured to receive a second synchronization message from the second apparatus at a second wavelength and in response to the first synchronization message, the first wavelength and the second wavelength are based on a reduction of a latency difference between the second synchronization message and the first synchronization message, and the processor is further configured to calculate a TO between the first apparatus and the second apparatus based on the reduction.
