    • The optical transmission equipment includes: a demultiplexer for demultiplexing a transmitted wavelength-multiplexed optical signal to first and second optical signals; a first variable dispersion compensation unit; a second variable dispersion compensation unit; a first error detector; a second error detector; and a dispersion compensation control unit for controlling dispersion compensation amounts of the first and second variable dispersion compensation units based on the detection result of the first or second error detector. Upon detection of a signal error in the first optical signal, the first variable dispersion compensation unit is controlled to change from a first compensation amount to a third compensation amount, and the second variable dispersion compensation unit is controlled to change from a second compensation amount to a fourth compensation amount.
    • 光传输设备包括:解复用器,用于将传输的波分复用光信号解复用到第一和第二光信号; 第一可变色散补偿单元; 第二可变色散补偿单元; 第一个误差检测器; 第二误差检测器; 以及色散补偿控制单元,用于基于第一或第二误差检测器的检测结果来控制第一和第二可变色散补偿单元的色散补偿量。 在检测到第一光信号中的信号误差时,控制第一可变色散补偿单元从第一补偿量变为第三补偿量,并且控制第二可变色散补偿单元从第二补偿量变为 第四补偿金额。

    • The image forming apparatus has a heat member for heating an unfixed image and is configured so that a longitudinal center of the heat member becomes a conveyance center of the recording material, the image forming apparatus including a central portion temperature detection part adjacent to the conveyance center, an end portion temperature detection part for detecting an end portion temperature of the heat member, and a width detection part for detecting a lateral width of the recording material, wherein the width detection part is disposed at a side opposite to a side at which the end portion temperature detection part is disposed with respect to the conveyance center position of the recording material. The image forming apparatus achieves the control for error setting of the recording material based on the width detection part and the end portion temperature detection part.
