摘要： The invention provides an optical communication system (10) comprising a plurality of mutually interconnected bi-directional optical waveguide rings (20, 30, 40, 50, 60) in which radiation modulated with communication traffic propagates. The radiation is partitioned into 32 distinct wavebands. Interfaces (70, 80, 90, 100, 110, 120) are included in the system (10) where communication traffic propagating in the rings transfers from one ring to another. Each interface (70) is capable of providing an all-optical waveband reconfigurable communication link between the rings (20, 30, 40, 50, 60). At each interface (70), conversion of optical radiation to corresponding electrical signals is not required when transferring communication traffic from one ring to another, thereby providing the system (10) with a potentially larger communication bandwidth compared to conventional optical communication systems. If required, the interfaces (70, 80, 90, 100, 110, 120) can include one or more of regenerative amplification (440, 850, 852, 854, 856, 858, 860, 862, 864) and wavelength-switching transponders (1332, 1410).
摘要翻译：本发明提供了一种光通信系统（10），其包括多个相互互连的双向光波导环（20,30,40,50,60），其中通过通信业务传播进行辐射调制。辐射分为32个不同的波段。接口（70,80,90,100,110,120）包括在系统（10）中，其中在环中传播的通信业务从一个环转移到另一个环。每个接口（70）能够在环（20,30,40,50,60）之间提供全光波段可重新配置的通信链路。在每个接口（70）处，当将通信业务从一个环转移到另一个环时，不需要将光辐射转换成对应的电信号，从而与传统的光通信系统相比，向系统（10）提供了可能较大的通信带宽。如果需要，接口（70,80,90,100,110,120）可以包括一个或多个再生放大（440,850,852,854,856,858,860,862,864）和波长切换转发器（1332,1410）。

摘要： An on/off switchable source of a continuous optical signal at a respective wavelength (λ2) is provided to be turned off when the wavelength (λ1) of the modulated incoming signal corresponds to the respective wavelength (λ2) generated by the source while turning said source on when the wavelength (λ1) of the incoming signal differs from the source wavelength (λ2). A Michelson interferometer is provided adapted to receive the incoming signal and the continuous optical signal generated by the source to produce an output signal. The Michelson interferometer is adapted to give rise to destructive viz. constructive interference when the incoming signal has first and second logical values, respectively. When the wavelength (λ1) of the incoming signal, which is not generally known a priori, corresponds to the source wavelength (λ2), the source is switched off and the output signal is a replica of the incoming signal regenerated at the interferometer. When the wavelength (λ1) of the incoming signal differs from the source wavelength (λ2), the source is switched on and the output signal is a replica of the incoming signal regenerated at the interferometer and wavelength converted to the source wavelength (λ2).

摘要： Methods and apparatus for maintaining a pre-determined ratio of a pilot tone power and a total mean optical power of an optical signal are provided. One apparatus includes an optical source coupled to provide an optical signal in response to a DC bias and an AC bias corresponding to a pilot tone signal. A processor is coupled to compute each of an AC component and a DC component of the optical signal from the same digitally sampled signal. A feedback control is coupled to vary at least one of the DC bias and the AC bias in accordance with a difference between a pre-determined value and a ratio of the AC and DC components.

摘要： A unique sensor is used to detect a transmission impairment that may have affected incoming optical channel signals. The sensor, more specifically, selects a group of the incoming channel signals and generates a first power signal, P0, over the selected group of signals and generates a second power signals, P1, over a weighted version of the selected group of channel signals. The sensor then generates, as a function of the first and second power signals, P0 and P1, a signal indicative of whether the particular transmission impairment affected the levels of individual ones of the incoming channel signals. If so, then control apparatus offsets the impairment accordingly.

摘要： An all-optical method of regenerating an optical return-to-zero format pulse signal of a first wavelength starts by introducing the input signal into a first end of a non-linear optical fiber to obtain a modified signal comprising pulses broadened in the wavelength domain. When this modified signal emerges from the second end of said non-linear optical fiber, a bandwidth slice is selected that is centered on a second wavelength so spaced from the first wavelength that its intensity is substantially unresponsive to weak pulses in the signal and relatively insensitive to intensity for other pulses. This slice is returned to the same non-linear optical fiber at its second end so that a further modified signal comprising pulses broadened in the wavelength domain will emerge from its first end. From this further modified signal a bandwidth slice centered on the first wavelength is selected as regenerated output. Regenerators operating in this way are also disclosed.
