摘要： Systems and techniques for multiple bit rate optical data transmission. A passive optical network includes an optical line termination unit (OLT) connected to one or more optical network units (ONUs) by optical elements. The OLT is capable of performing downstream transmission to the ONUs at each of a variety of different bit rates, and each ONU performs upstream transmission at one or more bit rates. The OLT can sense a bit rate of a received transmission and change its operation so as to receive and process the transmission exhibiting the sensed bit rate. Each of the ONUs receives and processes downstream transmissions at one or more bit rates, but each ONU is capable of maintaining a phase and frequency lock to downstream transmissions at all bit rates supported by the OLT. One or more of the ONUs may also receive and process downstream transmissions exhibiting different or changed bit rates.

摘要： A routing device such as either a 1:N demultiplexer or N:1 multiplexer can provide a power dissipation proportional to log2(N) by augmenting a conventional data demultiplexer/multiplexer with additional control circuitry. The control circuit ensures that control signals that trigger configuration of individual demultiplexer/multiplexer elements are propagated only along a data transmission path. Logic components of the control circuitry enable the multiplexers to be self-configuring and to prevent multiplexers from switching to elements with empty data buffers.

摘要： A method and apparatus for controlling traffic in an optical network having a plurality of OLTs for communicating with a plurality of PONs. A traffic controller receives traffic information concerning current traffic volume and, preferably with reference to a rules database, calculates the number of OLTs required to support the current traffic volume. A separate determination may be made whether a network reconfiguration is permitted at this time. If a reconfiguration is permitted, the traffic controller configures a traffic control switch to route the PON traffic to an from only the calculated number of OLTs. The traffic control switch may be implemented using a voltage-controlled optical fiber coupling or electronically, routing the traffic as electrical signals to and from electro-optical converters associated with each PON. The OLTs to be used may be selected by the traffic controller. The method and apparatus may also be used for fault management to route PON traffic through operational components when a failure of other components in the network is detected.

摘要： In a passive optical network, upstream transmission frames from an ONU to an OLT can include additional delimiters that assist in overcoming high signal distortion at the beginning of the frame that can obscure an initial frame delimiter. The second delimiter can be inserted into the frame at various locations within the frame known to the OLT such that the OLT can active a delimiter detector at the beginning of a timing window for delimiter detection. The ONU can assist the OLT in synchronizing the frame by ensuring that a frame header immediately follows a second delimiter or appears at the start of a first FEC code block following the second delimiter. Depending on where the ONU inserts the second delimiter in the frame generation process, the second delimiter may be scrambled and/or may form part of the FEC.

摘要翻译： 在无源光网络中，从ONU到OLT的上行传输帧可以包括附加的分隔符，其有助于克服在帧的开始处可能模糊初始帧定界符的高信号失真。 可以在OLT已知的帧内的各个位置处将第二分隔符插入到帧中，使得OLT可以在用于定界符检测的定时窗口的开始处激活定界符检测器。 ONU可以通过确保帧头紧跟在第二定界符之后来辅助OLT同步帧，或者出现在第二定界符之后的第一FEC码块的开始处。 根据ONU在帧生成过程中插入第二定界符的位置，第二定界符可以被加扰和/或可以形成FEC的一部分。

摘要： A processing device, configured to implement at least a portion of a scheduled medium-access protocol (SMAP) in a communication system, comprises a processor, a memory coupled to the processor, and one or more additional hardware modules. The functionality of the portion of the SMAP implemented in the processing device is partitioned between software, stored in the memory and executable by the processor, and hardware comprising the one or more additional hardware modules. In an illustrative embodiment, the processing device comprises a head-end device of a passive optical network, and the functionality comprises at least a scheduler and a grant generator, with the scheduler being implemented in the software and the grant generator being implemented in the hardware. As a result of this software-hardware partitioning, the scheduler is able to generate updated schedules at a rate which is independent of a rate at which the grant generator generates upstream channel access grants for subscriber devices of the system, thereby improving system performance.
