Embodiment Construction
[0039] The following further describes the present invention with reference to the accompanying drawings of the specification and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0040] Such as figure 2 As shown, the method for obtaining high-speed packets based on PON delay in this implementation includes the following steps:
[0041] 1) When the ONU in the PON system sends a serial upstream optical signal to the OLT and the OLT sends a serial downstream optical signal to the ONU, the upstream optical signal and the downstream optical signal are respectively converted into parallel electrical signals and output;
[0042] 2) Acquire the parallel electrical signals output in step 1) in real time to obtain uplink data and downlink data. The uplink data and downlink data are output to the physical layer for encoding, and converted back to serial optical signals and sent to the corresponding OLT or ONU; At the same time, a copy ...
