Abstract: An optical network unit (ONU) of an Ethernet passive optical network (EPON) and a control method thereof eliminates or substantially reduces instances of an ONU transmitting in time slots other than its allocated time slot. The ONU includes: a medium access controller for accessing a medium without temporal overlapping in order to transmit during one or more allocated TDM time slots without collision in upstream transmission to an optical line terminal; a burst-mode optical transceiver having a separately allocated wavelength before outputting the signal in the upstream transmission; and a complex programmable logic device for controlling an optical output of the burst-mode optical transceiver by monitoring an optical-output control signal from the medium access controller. An erroneous output from an ONU malfunction can be prevented from by cutting off the output once the duration of the allocated time slot has been reached.

Abstract: A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.

Abstract: A GE-PON (Gigabit Ethernet Passive Optical Network) system and media access control method for the same are disclosed. In the GE-PON system, by employing MAC attributes of the gigabit Ethernet frames, an OLT (Optical Line Termination) transmits a downstream window containing both a control frame having timeslot position and size information in association with at least two ONUs and Ethernet frames to an ODN (Optical Distribution Network). The OLT analyzes contents of RAUs in an upstream window transmitted from the ONUs in a TDMA method and received from the ODN, and permits timeslot position and size corresponding to each of the ONUs. A plurality of ONUs, connected to the ODN, have their respective timeslot position and size allocated in response to their respective information contained in the control frame of the downstream window. RAU frames are transmitted having queue information and Ethernet frames associated with the allocated timeslots. As a result, by the above MAC structure of the GE-PON system, the OLT can be quickly intercommunicated with a plurality of ONUs.

Abstract: A system and method for managing link status in Gigabit Ethernet passive optical network (GE-PON) units (ONUs) is disclosed. The GE-PON comprises one or more ONUs allocated data transmission periods, respectively. Each of the ONUs sends a report signal and a data signal in a corresponding one of the allocated data transmission periods. The report signal contains a signal to request allocation of a bandwidth for data signal transmission in a next window period. The GE-PON further comprises an optical splitter having its one side connected with the ONUs and its other side connected with at least one optical communication channel. The optical splitter switches an input signal to a desired destination. The GE-PON further comprises an optical line terminal (OLT) for determining whether the report signal is received, identifying a specific one of the ONUs having sent the report signal when the report signal is received, determining whether the data signal is received from the specific ONU in a specific one of the data transmission periods allocated to the specific ONU, and discriminating and managing a link status of the specific ONU in accordance with the determination made.
