Abstract:
1. A device for transporting optical network signals, comprising: an optical-to-electric conversion unit, adapted to convert upstream burst optical signals with a PON frame format as received into upstream electric signals, wherein upstream burst optical signals each have a different clock phase, and there is no optical power between the upstream burst optical signals; a receiving and processing unit, adapted to phase adjust the upstream electric signals from the optical-to-electric conversion unit into the upstream electric signals with a uniform bit or byte clock, and to convert the upstream electric signals into upstream data streams; an upstream optical channel data unit mapping module, adapted to map the upstream data streams from the receiving and processing unit to upstream optical channel data unit signals; and an upstream optical channel transport unit module, adapted to convert the upstream optical channel data unit signals from the upstream optical channel data unit mapping module into upstream signals with an optical channel transport unit format, and to transport the upstream signals with the optical channel transport unit format to an optical transport network.
