Reduction of synchronization errors in common air radio interface (CPRI) passive optical networks (PONS)

摘要

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