Patent ID: 8666249

Claim:
A method for processing uplink burst packets in a long reach passive optical network (LR-PON), comprising: receiving the uplink burst packets transmitted by an optical network unit (ONU) in a burst manner; converting a burst optical signal of the uplink burst packets into a continuous optical signal; and transmitting the continuous optical signal to a receiving device, wherein the converting the burst optical signal of the uplink burst packets into the continuous optical signal comprises: adjusting an optical power of the burst optical signal to obtain an adjusted optical signal, and converting the adjusted optical signal into an electrical signal; amplifying and shaping the electrical signal to obtain an amplified and shaped electrical signal; performing a clock data recovery on the amplified and shaped electrical signal to obtain a clock data recovered electrical signal; and converting the clock data recovered electrical signal into the continuous optical signal; and wherein the step of converting the clock data recovered electrical signal into the continuous optical signal comprises: determining an inter-packet gap between a clock data recovered electrical signal of a uplink burst packet and a clock data recovered electrical signal of a next adjacent uplink burst packet; filling the inter-packet gap with non-Consecutively Identical Digits (non-CID) bit or bits to obtain a continuous clock data recovered electrical signal; and converting the continuous clock data recovered electrical signal into a converted optical signal, and amplifying the converted optical signal to obtain the continuous optical signal.
