Abstract: A burst transmission method and a receiver resetting method and apparatus in a Passive Optical Network (PON) are provided. A burst receiver resetting method in a PON includes: receiving a preamble sequence and synchronizing data; after synchronizing the data, continuing to receive the data, and matching a Burst Terminator (BT); and resetting a receiver after successfully matching the BT. Meanwhile, an apparatus for implementing the method and a corresponding burst data transmission method are provided. By using the burst receiver resetting method and apparatus in the PON and the corresponding burst transmission method at an Optical Network Unit (ONU) burst transmission end, a Reach Extender (RE) does not need to unpack upstream burst bandwidth allocation information carried in downstream data.

Abstract: A method for updating stored information and an apparatus. A controller performs error correction code (ECC) decoding on stored data information based on the stored data information and stored ECC check information to generate an error-corrected codeword, where the error-corrected codeword includes error-corrected data information. The controller generates candidate to-be-written data information based on the error-corrected data information and a data update indication. The controller performs a mask operation on the candidate to-be-written data information based on the stored data information, and writes unmasked content in the candidate to-be-written data information into a memory.

Abstract: A signal receiving apparatus and method are provided. When a baseband signal is restored, an orthogonal polarization state of light does not need to be precisely controlled. This is easy to implement and can reduce system costs. The apparatus includes an optical splitter configured to split a first polarization multiplexing optical signal into at least two second polarization multiplexing optical signals, and input the two second polarization multiplexing optical signals into at least two optical signal processing modules. An optical signal processing module is configured to couple the second polarization multiplexing optical signal, and input a coupled optical signal to a photoelectric detector configured to convert the coupled optical signal into an analog signal. An analog-to-digital converter is configured to convert the analog signal into a digital signal, and input the digital signal to a digital signal processor configured to process the digital signal to obtain a baseband signal.

Abstract: The present invention provides a method and an apparatus for data packet switching, and an access switch and a switching system, so as to satisfy requirements of a datacenter for a switching bandwidth and a switching granularity. The method includes: receiving MAC frame control information; determining an interface used for forwarding an MAC frame according to the MAC frame control information and through performing a query on a MAC address forwarding table, where the interface used for forwarding the MAC frame includes a downlink interface, an uplink electrical packet switching network interface and/or an uplink optical packet switching network interface; transmitting a control signal to an electrical packet switching unit, so that the MAC frame is forwarded to the determined interface. According to the method provided in the present invention, the utilization rate of each interface can be improved.
