    摘要: Disclosed herein is an apparatus and method for detecting an optical line fault in a Passive Optical Network (PON). The apparatus includes an optical distribution unit configured to, when a multiplexed signal of a downstream light signal and a monitoring light signal is input, distribute the multiplexed signal to an Optical Network Unit (ONU) of a first optical path and to a second optical path. An optical layer management unit is installed in the second optical path and is configured to set a time at which the monitoring light signal of the multiplexed signal provided to the second optical path is received to a starting time of monitoring light measurement, compare a monitoring light signal reflected and returned from the ONU with a signal pattern obtained when no fault occurs, and then determine whether a fault has occurred in a distribution network.

    摘要: Disclosed herein are an optical network unit and a method for controlling the unit. In a passive optical network system, an optical transceiver of the optical network unit performs a wavelength change of an optical signal according to a wavelength setting command transferred from a media access control (MAC) unit and monitors a wavelength change state and reports the monitored wavelength change state to the MAC unit. When the wavelength malfunction occurs, the MAC unit blocks an uplink optical transmission of the optical transceiver.

    摘要: Provided are a system and method for setting a downstream forward error correction code for a downstream frame which is transmitted from an optical line terminal to an optical network unit in a time division multiplexing passive optical network. A system for setting a downstream forward error correction code in a time division multiplexing passive optical network includes: an optical line terminal configured to change a downstream forward error correction (FEC) indication included in a downstream frame and set a downstream FEC indication counter included in the downstream frame to transmit the downstream frame; and an optical network unit configured to receive the downstream frame from the optical line terminal and synchronize an FEC setting of the optical network unit with the FEC setting of the optical line terminal as a result of detection of the downstream FEC indication and downstream FEC indication counter included in the downstream frame.

    摘要: The inventive concept relates to an optical line terminal registering optical network terminals having overlapping serial numbers. The optical line terminal may include a memory storing serial number information of optical network terminals of which a registration is completed in a storage region; and a control part that if a serial number by a serial number request is received from optical network terminals, the received serial number is compared with the serial number information of the memory and if they overlap each other, a previously set preliminary identifier is allocated to the optical network terminal having an overlapping serial number.

    摘要: A fast protection switching method for a Passive Optical Network (PON). When performing protection switching from an operation link (an operation network) to a protection link (a protection network) in a PON, the fast protection switching method enables rapidly updating Equalization Delay (EqD) values, even if the EqD values are different for Optical Network Terminals (ONTs) of varying distances.
