摘要： Consistent with the present disclosure, data, in digital form, is received by a transmit node 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 forming a plurality of corresponding carriers. The plurality of carriers are then optically combined with a fixed spacing combiner to form a superchannel of a fixed capacity. Accordingly, the number of carriers are selected according to a modulation format and symbol rate to realize the fixed capacity, for example. The superchannel is then transmitted over an optical communication path to a receive node. At the receive node, the superchannel is optically demultiplexed from a plurality of other superchannels. The plurality of carriers are then supplied to a photodetector circuit, which receives additional light at one of the optical signal carrier 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 the carriers is unnecessary.
摘要翻译： 根据本公开，数字形式的数据由光通信的发送节点接收，并由数模转换器（DAC）转换成模拟信号以驱动调制器。 调制器又根据形成多个相应载波的接收数据调制多个波长中的一个波长的光。 然后将多个载波与固定间隔组合器光学组合以形成固定容量的超级通道。 因此，例如，根据调制格式和符号率来选择载波的数量以实现固定容量。 然后，超信道通过光通信路径传输到接收节点。 在接收节点处，超级信道从多个其他超级信道被光解复用。 然后将多个载波提供给光电检测器电路，该电路从本地振荡器激光器接收来自光信号载波波长的其中一个附加光。 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ADC的输出进行滤波，使得载波的光解复用是不必要的。
