摘要： Consistent with the present disclosure, data, in digital form, is received by a transmit nodes of an optical communication, and converted to analog signal by a digital-to- analog converter (DAC) to drive a modulator. The modulator, in turn, modulates light at one of a plurality of wavelengths in accordance with the received data. The modulated light is then transmitted over an optical communication path to a receive node. At the receive node, the modulated optical signal, as well as other modulated optical signals are supplied to a photodetector circuit, which receives additional light at one of the optical signal wavelengths from a local oscillator laser. An analog-to- digital converter (ADC) is provided in the receive node to convert the electrical signals output from the photodetector into digital form. The output from the ADC is then filtered in the electrical domain, such that optical demultiplexing of individual channels is unnecessary.
摘要翻译：与本公开一致，数字形式的数据由光通信的发射节点接收，并由数模转换器（DAC）转换成模拟信号以驱动调制器。调制器又根据接收的数据调制多个波长中的一个波长的光。调制光然后通过光通信路径传输到接收节点。在接收节点处，调制的光信号以及其它调制的光信号被提供给光接收器电路，光电检测器电路从本地振荡器激光器接收来自光信号波长之一的附加光。在接收节点中提供模数转换器（ADC）以将从光电检测器输出的电信号转换为数字形式。然后在电域中对来自ADC的输出进行滤波，使得各个信道的光解复用是不必要的。

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.
摘要翻译：根据本公开，提供了紧凑型发射机，其可以根据光链路要求生成具有不同调制格式的光信号。优选地，发射机包括具有多个激光器和调制器的光子集成电路。控制电路调节提供给调制器的驱动信号，使得可以从调制器输出具有所需调制格式的光信号。因此，例如，发射机可以用于输出具有适合于长距离或潜艇链路的调制格式的光信号，以及具有较短距离的链路。此外，相同的光子集成电路可以提供具有不同调制格式的光信号，使得例如沿着链路落下并因此行进更短距离的那些光信号可以具有第一调制格式，而其它光信号传播链路的整个长度的信号可以具有更适合于较长距离的第二调制格式。

摘要： Embodiments of the present invention compensate for skew across a wavelength division multiplexed network. The network is a wavelength division multiplexed optical transport network. The skew compensation can be performed electrically or optically. It can be performed on the transmission side of the network, the receiver side of the network or at any intermediary node on the network.
