摘要： One embodiment of the present invention provides a system for mitigating Raman crosstalk between downstream data and video transmission in an Ethernet passive optical network (EPON), wherein the EPON includes an optical line terminal (OLT) and one or more optical network units (ONU's). During operation, the system transmits a data stream from the OLT to the ONU's on a first wavelength that is substantially at 1490 nm. The system also transmits a video signal stream from the OLT to the ONU's on a second wavelength that is substantially at 1550 nm. The system modifies the bit sequence for the data stream to change the power spectral distribution (PSD) for the data stream, thereby reducing power spectral content in the frequency range where significant Raman crosstalk can occur between data and video signal streams.

摘要： Provided is a system that facilitates construction of a forward error correction (FEC) coded Ethernet frame. During operation, the system receives a conventional Ethernet frame. The system then generates a number of FEC parity bits for the conventional Ethernet frame and inserts a start sequence before the conventional Ethernet frame. Next, the system appends an even- or odd-delimiter (TFEC_E210, TFEC-O 220) to the conventional Ethernet frame. The even-delimiter is used to separate the conventional Ethernet frame from the FEC parity bits if the last symbol of the conventional Ethernet frame is in an odd-numbered position. The odd-delimiter is used to separate the conventional Ethernet frame from the FEC parity bits if the last symbol of the conventional Ethernet frame is in an even-numbered position. The even-delimiter and the odd-delimiter are selected such that there is a sufficiently large Hamming distance between them.
摘要翻译：提供了一种有助于构建前向纠错（FEC）编码以太网帧的系统。在操作期间，系统接收传统的以太网帧。然后，该系统为常规以太网帧生成多个FEC奇偶校验位，并在常规以太网帧之前插入起始序列。接下来，系统将偶数或奇数分隔符（TFEC_E210，TFEC-O 220）附加到常规以太网帧。如果常规以太网帧的最后一个符号处于奇数位置，则偶数分隔符用于将常规以太网帧与FEC奇偶校验位分离。如果常规以太网帧的最后一个符号处于偶数位置，则奇数分隔符用于将常规以太网帧与FEC奇偶校验位分离。偶数分隔符和奇数分隔符被选择为使得它们之间具有足够大的汉明距离。

摘要： One embodiment provides a media access control (MAC) module facilitating operations of an Ethernet passive optical network (EPON). The MAC module includes a frame formatter configured to generate a MAC control frame. The generated MAC control frame includes at least one of: an organizationally unique identifier (OUI) field, an OUI-specific operation code (opcode) field, and a number of fields associated with the OUI-specific opcode. Transmission of the MAC control frame facilitates realization of an EPON function based on the fields associated with the OUI-specific opcode.

摘要： One embodiment of the present invention provides a method for facilitating asymmetric line rates in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system provides a downstream code-group clock, wherein each cycle thereof corresponds to a code group transmitted from the central node to a remote node. The system also provides an upstream code-group clock, wherein each cycle thereof corresponds to a code group received at the central node from a remote node. In addition, the system provides a multi-point control protocol (MPCP) clock, wherein the frequency ratio of the MPCP clock to the downstream code-group clock is different from the frequency ratio of the MPCP clock to the upstream code-group clock, thereby allowing the downstream transmission to be performed at a faster line rate than the upstream transmission line rate.

摘要： One embodiment of the present invention provides a system that decrypts downstream data in an Ethernet passive optical network (EPON). During operation, the system receives a data frame which is encrypted based on a remote input block and a session key, wherein the remote input block is constructed based on a remote cipher counter and a remote block counter. The system adjusts a local cipher counter based on a received checksum located in a preamble of the data frame, wherein the local cipher counter is substantially synchronized with the remote cipher counter. In addition, the system truncates the local cipher counter by discarding n least significant bits thereof. The system then constructs a local input block based on the truncated cipher counter and a local block counter for the received data frame. Next, the system decrypts the data frame based on the local input block and the session key.
