摘要： Consistent with the present disclosure, a compact transmitter is provided that can generate optical signals having different modulation formats depending on optical link requirements. Preferably, the transmitter includes a photonic integrated circuit having multiple lasers and modulators. A control circuit adjusts the drive signals supplied to the modulators such that optical signals having a desired modulation format may be output from the modulators. Thus, for example, the transmitter may be used to output optical signals having a modulation format suitable for long haul or submarine links, as well as for links having a shorter distance. Moreover, the same photonic integrated circuit may supply optical signals with different modulation formats, such that, for example, those optical signals that are dropped along a link, and thus travel a shorter distance, may have a first modulation format, while other optical signals that travel the entire length of the link may have a second modulation format that is more suited for longer distances.

The network is a wavelength division multiplexed optical transport network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

摘要： Chromatic dispersion is determined based on the arrival times of different frames of data in a wavelength division multiplexed (WDM) system having an optical communication link. Namely, a first frame is transmitted on a first optical channel, which is supplied to the optical communication link. A second frame is then transmitted on a second optical channel and the transmission time difference between the two frames is obtained. At a receive end, the difference in arrival times of the two frames is measured to obtain a relative time delay between the first and second frames. The relative time delay is the sum of the transmission time difference and the propagation time difference (the time difference attributable to chromatic dispersion) between the two frames. Thus, by subtracting the transmission time difference from the relative time delay, the propagation time difference can be obtained. The chromatic dispersion in units of picoseconds/nm can be obtained by dividing the propagation time difference by the difference in wavelength between the first and second optical channels.
摘要翻译：基于具有光通信链路的波分复用（WDM）系统中的不同数据帧的到达时间来确定色散。也就是说，在提供给光通信链路的第一光信道上发送第一帧。然后在第二光信道上发送第二帧，并且获得两帧之间的传输时间差。在接收端，测量两帧的到达时间差，以获得第一和第二帧之间的相对时间延迟。相对时间延迟是两帧之间的传输时间差和传播时间差（归因于色散的时间差）之和。因此，通过从相对时间延迟减去传输时间差，可以获得传播时间差。通过将传播时间差除以第一和第二光学通道之间的波长差，可以获得以皮秒/ nm为单位的色散。

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 to compute a route through a network having both digital nodes and optical express-thru nodes. According to various embodiments of the invention, a network topology is generated in which both digital nodes, optical express-thru nodes, and optical nodes are identified, and both physical and virtual links between these nodes are mapped. The network connectivity is identified, at least in part, by broadcasting a local link state advertisement and optical carrier group binding information to neighboring nodes, which enables both physical and virtual neighboring nodes to be identified. Once a topology is generated, both physical and virtual link characteristics are analyzed to ensure link diversity for traffic through the network and load balancing functionality across the network.

摘要： A high capacity optical transmitter implemented on a photonic integrated circuit chip comprises' a single light source (108) which supplies a continuous wave having a particular wavelength to a plurality of modulators (106,112,126,130) to form modulated optical information signals. A phase shifter (114,128) is coupled to at least one of ' the modulators and' is used to shift the phase of the corresponding modulated optical information signal associated with a particular modulator. A polarization beam combiner (138) receives each of the modulated optical information signals from the modulators and the modulated optical information signal from the phase shifter and combines each of these signals to form a polarization multiplexed differential quadrature phase-shift keying signal. The light source, the plurality of modulators, the phase shifter and the polarization beam combiner are all integrated on the chip.

摘要： A wavelength independent multi-section optical coupler having at least three optical couplers, and at least two differential phase cells. Each optical coupler has two waveguides forming a coupling region having a net coupling value. The coupling value for each coupling region of the at least three optical couplers is different than the coupling values of the other two coupling regions.

摘要： Optical autodiscovery is provide between two optical modules to insure that when an optical signal is coupled between the two optical module, the optical signal from a first module does not interfere with operation of a second module. The autodiscovery is implemented by sending an optical identification signal from the first optical module via the coupling to the second optical module from which signal, the second optical module can verify and determined acceptance of the coupled first optical module. During this autodiscovery process, the optical identification signal from the first optical module may be attenuated or shifted in optical spectrum so as not to interfere with the operation of the second optical module. Autodiscovery may also be employed in cases where a first optical module is to receive an optical signal from a second module.
