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 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.

Abstract: MAC (Media Access Control) for an EPON (Ethernet Passive Optical Network system) defined in an IEEE (Institute of Electrical and Electronics Engineers) 802.3ah EFM (Ethernet in the First Mile) standard is implemented using general MAC based on an IEEE 802.3 standard. LLID (Logical Link ID) information is inserted at a predetermined position of a frame outside its preamble and the frame containing the LLID information is transferred to a higher layer so that general MAC can be used as MAC for the EPON system. A physical layer of the EPON system contains LLID information within a preamble and transfers the preamble containing the LLID information. An RS (Reconciliation Sublayer) configures a new Ethernet frame by inserting the LLID information at a predetermined position of the Ethernet frame outside the preamble. The RS transfers the new Ethernet frame to a higher data link layer of the EPON system. The data link layer transfers the new Ethernet frame containing the LLID information.

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 translation: 公开了一种允许在无源光网络中对基于IP的广播服务进行条件访问的解决方案。 当用户通过选择广播信道来请求广播业务时，IP机顶盒将该请求转换成IGMP加入消息，并将该消息转发给订户侧的ONU / ONT单元。 ONU / ONT将消息传递到与路由器互通的OLT，同时存储接收到消息的端口的映射信息和所选信道的MAC地址。 此后，OLT提取关于IP机顶盒的MAC地址和所请求的广播数据的信息。 OLT将提取的信息与订户的订阅信息进行比较，并确定是否提供所请求的广播服务。 如果可以提供广播服务，则从广播服务器提供的广播数据基于存储的映射信息经由ONU / ONT被发送到IP机顶盒。
