摘要： A system and method of providing a transmission span that compensates for signal attenuation, dispersion, and nonlinearity of an optical signal communicated between two line units of a transmission link includes dividing the transmission span into a plurality of fiber segments and selecting a particular fiber for each of the segments. The fiber selection and arrangement of fibers within the span can be selected in accordance with the nonlinearity, dispersion conditions, and distributed gain conditions of the constituent fibers. In a three segment map, the first segment can provide low non linearity, the third segment can provide distributed gain, and the second segment can compensate for the dispersion of the first and third segments. The span can be used, e.g., for distributed Raman amplification. The span can alternatively include a two segment map, a four segment map, or a map with additional segments.

摘要： An optical receiver for receiving a signal from an optical fiber in a fiber-optic digital transmission system that includes a first low noise optical amplifier to amplify an input optical signal. The first low noise optical amplifier has an input 3 dB compression point lower than the desired system input sensitivity at a desired bit rate. A high power optical amplifier further amplifies the amplified optical signal, and has an automatic gain control for output signal leveling at a desired operation point of the transmission system. A high current photodetector converts the further amplified optical signal from the high power optical amplifier to an electrical signal that drives a retiming circuit without requiring further amplification of the electric signal.

摘要： A method and apparatus for increasing the upper frequency range of an optical communication system, particularly one designed to communicate over, repeaterless, distances. A series of temporally interleaved optical solitons of different frequencies are generated, and transmitted and detected by wavelength division multiplexing. An adiabatic transmission line forms part of the transmission link, and serves to narrow the bandwidth of the pulses during propagation. As a result, one can generate the solitons with substantially overlapping spectra, thus increasing the rate at which they are produced, but, because of the narrowed spectra, still resolve them in frequency at the system's receiver.

摘要： An optical intensity modulator which uses a Sagnac interferometer having an electro-optic phase modulator therein. An electric modulation signal is delivered to the modulator, and the latter is selected so that the phase velocity of optical and electrical signals are comparable in it. This causes the optical signal from one interferometer arm to copropagate through the modulator with the electrical signal, increasing interaction time with it, and causes the optical signal from the other arm to counterpropagate with the electric signal, reducing interaction time. In addition to phase modulating the optical signals by the electrical signal, the electro-optic effect in the modulator phase shifts the optical signals with respect to one another, permitting them to form a non-zero interference pattern, whose intensity corresponds to the electrical signal. In one embodiment, the interferometer has a non-reciprocal device to impose a constant phase difference between the counterpropagating optical signals, which permits one to place the system's setpoint to any arbitrary point on the system's transmissivity versus phase response, e.g. large signal and/or linear response.
摘要翻译：一种光强调制器，其使用其中具有电光相位调制器的Sagnac干涉仪。电调制信号被传送到调制器，并且选择后者，使得光信号和电信号的相位速度在其中是相当的。这使得来自一个干涉仪臂的光信号通过调制器与电信号共同传播，增加与其的交互时间，并且使来自另一个臂的光信号与电信号相反地传播，从而减少了交互时间。除了通过电信号对光学信号进行相位调制之外，调制器相位中的电光效应相对于彼此移动光信号，允许它们形成非零干涉图案，其强度对应于电信号。在一个实施例中，干涉仪具有不可逆设备，以在反向传播光信号之间施加恒定的相位差，这允许将系统的设定点放置在系统的透射率相对于相位响应的任何点上，例如，大信号和/或线性响应。
