摘要： Client signals to be transported in a transmission network, particularly an optical transmission network, may have different payload envelope rates and are digitally mapped on the client egress side into first transport frames (also referred to as iDTF frames, or intra-node or internal digital transport frames), at the client side for intra-transport within terminal network elements (NEs) and further digitally mapped into second transport frames (also referred to as DTFs or digital transport frames) for inter-transport across the network or a link which, through byte stuffing carried out in the first transport frames so that they always have the same frame size. As a result, the system of framers provides for a DTF format to always have a uniformly universal frame rate throughout the network supporting any client signal frequency, whether a standard client payload or a proprietary client payload, as long as its rate is below payload envelope rate of the client signal. At the client signal ingress side, the signal are digitally demapped from the second transport frames (DTF format) into the first transport frames where the stuff bytes are removed and accordingly processed at an intermediate node element before further transport, or digitally demapped from the first transport frames (iDTF format) to reproduce or reassemble the client signal or signals comprising the client payload at the client payload envelope rate for reception at the client's equipment. Among various features disclosed, two predominate features are (1) a single channel or network rate for transport of all signals between network elements (NEs) and end terminal network elements and (2) the digitally wrapping of different types of payloads into N client side or first frames using stuff bytes to render each client side frame size equal to a predetermined value. Then the stuffed first frames are wrapped into line side or second frames for transport over the network at the same high speed line rate for all digitally wrapped client signals. The client side framers may be, for example, running at the lowest signal rate encountered, to digitally wrap then into parallel N client signals or digitally wrap a client signal multi-sected into N parts, where these two different client signals have different payload rates.
摘要翻译：要在传输网络，特别是光传输网络中传输的客户端信号可以具有不同的有效载荷包络速率，并且在客户端出口侧被数字地映射到第一传输帧（也称为iDTF帧，或节点内部或内部数字传输帧），在客户端用于在终端网元（NE）内进行内部传输，并进一步数字地映射到第二传输帧（也称为DTF或数字传输帧），用于通过网络进行跨传输，或链路，通过在第一个传输帧中执行的字节填充，使得它们总是具有相同的帧大小。因此，成帧器系统提供了一种DTF格式，在整个网络中始终具有统一的通用帧速率，支持任何客户端信号频率，无论是标准客户机有效载荷还是专有客户端有效载荷，只要其速率低于有效载荷客户端信号的速率。在客户端信号入口端，信号从第二传输帧（DTF格式）被数字地解映射到第一传输帧中，其中填充字节被去除，并且在进一步传输之前在中间节点元素处进行处理，或者从第一传输帧进行数字解映射传输帧（iDTF格式）以客户端的有效载荷包络速率再现或重新组合客户端信号或包括客户端有效载荷的信号，以便在客户端的设备处接收。在所公开的各种特征中，两个主要特征是（1）用于在网络元件（NE）和终端终端网络元件之间传输所有信号的单个信道或网络速率，以及（2）将不同类型的有效载荷数字地包装到N个客户端或使用填充字节的第一帧来呈现每个客户端帧大小等于预定值。然后，填充的第一帧被包装成线路侧或第二帧，以便以相同的高速线路速率在网络上传输用于所有数字包装的客户端信号。客户侧构造器可以例如以遇到的最低信号速率运行，以数字方式将其并入N个客户端信号，或将多个客户端信号数字地包围N个部分，其中这两个不同的客户信号具有不同的有效载荷率。

摘要： The present invention provides a system, apparatus and method for recovering a client signal clock. The present invention is able to more effectively remove jitter within a clock signal by providing a phase shifting element in the feedback of a PLL system to compensate for sudden changes in an input reference clock. The PLL system provides flexible clock recovery so that it can accommodate various payload types because it extracts a client clock signal independent of a corresponding justification count number.

摘要： Optical subcarriers may be employed to transmit data in a point-to-multi-point network whereby a hub node including a network switch receives such data from a client and transmits information indicative of such data to multiple leaf or network nodes, where data intended for such leaf node is output. Often the rate at which data is supplied to the hub node is different than the rate at which information indicative of the data is transmitted. Moreover, the client data may have a format that is different than that associated with the transmitted information indicative of the client data. Consistent with the present disclosure, client data is inverse multiplexed to lower data rate streams and then multiplexed to a plurality of inputs, each of which corresponding to a respective optical subcarrier. Information indicative of the data may be allocated to multiple subcarriers, if the a single carrier lacks sufficient capacity or bandwidth to meet the bandwidth requirements of the leaf node. Buffer circuits may also be employed to "shape" or delay the outputs or flows of the multiplexer so that data is fed, for example, to a transmit portion of chip 200b of the network switch at a uniform rate rather than in non-uniform data bursts, which, under certain circumstances, could exceed the capacity of such transmit portion. In a further example, leaf nodes include circuitry for monitoring the amount of received data, and, if such received exceeds a certain threshold, a request is sent from the leaf node to the hub to transmit data at a rate equal to or substantially equal to the received data rate. As a result, symmetric data flows may be achieved whereby the leaf nodes transmit and receive data at the same or substantially the same rate.

摘要： A photonic integrated circuits (PICs), also referred to as opto-electronic integrated circuits (OEICs), and more particularly to a PIC in the form of an optical receiver PIC or RxPIC for use in an optical transport networks. Also, an optical transmitter PIC (TxPIC) is also disclosed in conjunction with an RxPIC in an optical transport network. The chip is cast from an InP wafer and is made from Group III-V elemental materials in the InGaAsP/InP regime with fabrication accomplished through selective metalorganic vapor phase epitaxy (MOVPE) or also known as metalorganic chemical vapor deposition (MOCVD). Integrated on the chip, starting at the input end which is coupled to receive multiplexed optical data signals from an optical transport network is an optical amplifier, an optical demultiplexer, and a plurality of on-chip photodiodes (PDs) each to receive a demultiplexed data signal from the AWG DEMUX for optical-to-electrical signal conversion. The optical input amplifier may be an onchip gain clamped semiconductor optical amplifier (GC-SOA) or an off-chip fiber amplifier. The optical input amplifier may be optional if the channel signal demultiplexer provides for minimal insertion loss which is optimum with a properly designed arrayed waveguide grating (AWG) demultiplexer. A method of in-wafer testing of RxPIC chips is also described.

摘要： Embodiments of the present invention analyze a plurality of parallel channels and identify specific channel(s) that have skew outside of an acceptable skew error margin. In certain embodiments, this skew is identified by determining the timing misalignment between a channel under test and a deskew channel. Other channels within the plurality of channels are masked by transmitting a repeating masked bit pattern. This timing misalignment may be measured by comparing a segment within the channel under test to a corresponding segment within the deskew channel and identifying a time differential between the two segments.
