摘要： PROBLEM TO BE SOLVED: To reduce cross-phase modulation since different optical signals may be transported on the same link, in certain situations, cross-phase modulation (XPM) between the signals may occur, cross-phase modulation is a non-linear optical effect where one wavelength affects the phase of another wavelength, and cross-phase modulation may cause undesirable effects in phase-modulated signals. SOLUTION: A system includes sending instructions to a phase modulation array including channel pixel sets that modulate phases of channels. The channel pixel sets include a first channel pixel set that modulates a first phase of a first channel and a second channel pixel set that modulates a second phase of a second channel that uses a phase modulation format. The first channel pixel set is instructed to modulate the first phase at a first constant phase. The second channel pixel set is instructed to modulate the second phase at a second constant phase different from the first constant phase in order to create a group delay between the first channel and the second channel.

摘要翻译：要解决的问题：为了减少交叉相位调制，因为不同的光信号可能在相同的链路上传输，在某些情况下，信号之间可能发生交叉相位调制（XPM），交叉相位调制是非相位调制一个波长影响另一个波长的相位的线性光学效应，并且相位调制可能导致相位调制信号的不期望的影响。解决方案：系统包括向包括调制通道相位的通道像素组的相位调制阵列发送指令。通道像素组包括调制第一通道的第一相位的第一通道像素组和调制使用相位调制格式的第二通道的第二相位的第二通道像素组。指示第一通道像素组在第一恒定相位调制第一相位。指示第二通道像素组以与第一恒定相位不同的第二恒定相位调制第二相位，以便在第一通道和第二通道之间产生组延迟。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method and system for communicating optical traffic that substantially eliminates or reduces at least some of the disadvantages and problems associated with conventional methods and systems. SOLUTION: A method for communicating optical traffic includes the stages of adding optical traffic to an optical ring comprising a plurality of nodes and of communicating the optical traffic on the optical ring. The optical traffic comprises a plurality of virtual waveband which comprise a first virtual waveband of traffic comprising a first number of wavelengths and a second virtual waveband of traffic comprising a second number of wavelengths. The second number is different from the first number. The method also includes the stages of dropping the first virtual waveband of traffic at a first node of the plurality of nodes and of dropping the second virtual waveband of traffic at a second node of the plurality of nodes.

摘要： PROBLEM TO BE SOLVED: To provide a module scalable optical network system. SOLUTION: A node of an optical ring has an in-line switch, which outputs an inputted signal light to a coupler and then outputs the signal light from the coupler to the optical ring in a first state. In the first state, the switch inputs a signal light from itself and then returns a first branched light of the signal light, to the switch so as to output to the original optical ring, and branches a second branched light of the signal light to distribution elements. The distribution element inputs the second branched light to output its traffic. A filter removes a channel of the first branched light to generate a passing signal, and a composite element inputs the traffic to be inserted into the optical ring, to generate an insertion signal. An insertion coupler is connected with a second switch, and inputs the passing signal, when the second switch is in the first state. Subsequently, the insertion coupler adds the insertion signal to the passing signal to generate a composite signal, and then outputs it to the switch. COPYRIGHT: (C)2006,JPO&NCIPI
