摘要： Proposed is a method of equalizing an optical signal that has an overall bandwidth formed on a number of adjacent spectral slots, wherein the signal comprises a set of non-overlapping subcarrier signals. A distribution of the subcarrier signals onto the slots is such, that at least one slot is occupied by more than one subcarrier signal. The signal is received and amplified. Respective power levels are measured for the subcarrier signals. Distribution data is provided, which indicates the distribution of the subcarrier signals onto the spectral slots. Power level data is provided, which indicates for the spectral slots respective desired power levels. For the spectral slots respective attenuation values are derived, using the measured power levels, the distribution data and the power level data. Finally, the optical transmission signal is attenuated within the spectral slots individually, using the derived attenuation values.

摘要： An optical communication system including optical transmitters, in which every two adjacent transmitters are interconnected through a working transmission line and an auxiliary transmission line and an optical signal is transmitted through one of the transmission lines. Each transmitter has an optical amplifier and a controller. The optical amplifier of an optical transmitter amplifies an optical signal inputted through one of the transmission line carrying the optical signal between the optical transmitter and the upstream-side adjacent optical transmitter and outputs an optical signal containing a signal component and a noise component. The controller controls the level of the optical signal outputted from the optical amplifier so that the signal component of the optical signal may be at a predetermined level, and corrects the level of the optical signal when the transmission line carrying the optical signal between the optical transmitter and the upstream-side adjacent optical transmitter or between two upstream-side optical transmitters is changed from one to the other of the two transmission lines.

摘要： A wavelength multiplexer comprises a plurality of variable attenuators (12) for variably attenuating a plurality of optical signals of different wavelengths, an optical multiplexer (14) for combining optical outputs from the attenuators, and an optical amplifier (16) for amplifying the optical output from the optical multiplexer. To avoid the effects of the leakage light of unused wavelength on the optical amplification of wavelength in use, an optical switch (46) is provided before the variable attenuators, and sufficient attenuation of unused wavelength is secured by switching to an attenuator film.

摘要： A process for producing an optical filter of which the dependence of the gain on the wavelength is suppressed. The light power of the input signal of an optical amplifier (4) and the output power and the light power of the output signal of a pumping source (8) are set at the power used at the time of communication, and the total power of the pseudo input light of a plurality of wavelengths (μ1, μ2, ..., μn) from light sources (1a) and the input light (probe light) of one of the wavelengths of a communication band from a light source (1m) is set at the total power of communication input signals of a plurality of a wavelengths at the time of wavelength multiplexing communication. Then the attenuation of the input light corresponding to the wavelength of the probe light is found by inputting the input light to the amplifier (4) in the set state and variably adjusting the attenuation during transmission from the light source (1m) to the input terminal (14) of the amplifier (4) so that the output power of the probe light from the amplifier (4) can fall within a range from the maximum output power of the pseudo output power to the minimum output power of the output power. By repeating the above-mentioned operation while changing the wavelength of the probe light, the loss spectrum of the attenuation corresponding to each wavelength one to one is set to the optical filter.
摘要翻译：一种制造可以抑制光放大器的增益的波长依赖性的滤光器的方法。输入信号光功率，泵浦光源的输出功率（8）和光放大器（4）的输出信号光功率被设置为用于光通信系统的功率值，并且模拟输入光的总功率来自光源（1a）的多个波长（λ1，λ2，...λn）和来自光源（1m）的输入光（探测光）被设置为等于输入信号的总功率在波分复用传输系统中使用的多个波长。在这种情况下，输入光被复用并发射到光放大器（4）中，并且可变地调节从光源（1m）到光放大器（4）的输入端（14）的衰减量，使得输出来自光放大器（4）的对应于探测光的功率将在由与模拟输入光相对应的输出功率的最大值和最小值确定的范围内，以确定与探测光的波长对应的衰减量。在改变探测光的波长时重复上述操作，并且将滤光器的损耗谱设置为与各个波长一一对应的衰减量的损耗谱。
