Abstract: A wavelength division multiplexing passive optical network system is provided. A central office generates a multi-mode light having a mode interval equal to a period interval of a multiplexing filter of the remote node and the multi-mode light is used to control a wavelength of an uplink transmission optical signal of the optical network unit. A remote node multiplexes the multi-mode light with the multiplexing filter to transmit the multiplexed multi-mode light to the optical network unit and demultiplexes the uplink transmission optical signal to transmit the demultiplexed uplink transmission optical signal to the central office. An the optical network unit generates the uplink transmission optical signal by modulating a data signal with a Fabry-Perot laser which uses the multiplexed multi-mode light as an injection optical source. Accordingly, it is possible to control a wavelength of a transmitter of the optical network unit by using the injection optical source generated by the central office.

Abstract: A fragmentation repetition detection apparatus (410) for detecting an IP fragmentation repetition which may occur in a multicast or unicast environment is provided. The fragmentation repetition detection apparatus (410) includes a packet capturing unit (411) which captures a received packet, a fragmentation repetition detector which detects whether or not the captured packet is a packet which is repetitively fragmented, and a path maximum transmission unit (PMTU) transmitter (414) which transmits PMTU information acquired by the fragmentation repetition detector (412) to a server which transmits the packet when the captured packet is a packet which is repetitively fragmented. Since a packet is transmitted by readjusting a PMTU, a fragmentation of an IP packet can be prevented.
