Abstract:
1. A method for processing uplink optical burst packets in a long reach passive optical network, the method comprising: receiving the uplink optical burst packets transmitted by an optical network unit in a burst manner; converting the uplink optical burst packets into an electrical signal; determining an inter-packet gap between an uplink burst packet of the electrical signal and a next adjacent uplink burst packet of the electrical signal, wherein determining the inter-packet gap comprises: obtaining an end position of the uplink burst packet of the electrical signal; obtaining a start position of the next adjacent uplink burst packet of the electrical signal; and determining the inter-packet gap according to the end position and the start position; filling the inter-packet gap of the electrical signal with non-consecutive identical digit bits; converting the electrical signal after being filled with the non-consecutive identical digit bits into a continuous optical signal; and transmitting the continuous optical signal to a receiving device; wherein a length of the non-consecutive identical digit bits meets a clock data recovery capability of the receiving device.
