摘要： An optical transmission apparatus that improves the reliability of system operation by efficiently limiting the line speed of a signal sent from a user with a guard mechanism. An optical branching section makes an optical signal branch in two directions. A through branching line passes an optical signal in its original condition and sends the optical signal as a through optical branch signal. A delay branching line delays an optical signal by a delay amount set and sends the optical signal as a delayed optical branch signal. An optical multiplexing section combines the through optical branch signal and the delayed optical branch signal. A line speed limitation section limits acceptance of the line speed of the optical signal inputted by generating a multiplexed optical signal that meets a pulse mask standard for an optical signal to be passed for the optical signal which is sent at a line speed lower than or equal to a line speed settled under contract with a user and which is to be passed and by setting the delay amount for generating a multiplexed optical signal that does not meet a pulse mask standard for an optical signal acceptance of which is to be refused for the optical signal which is sent at a line speed higher than the line speed settled under contract with the user and acceptance of which is to be refused.

摘要： A power-down delay unit 15 for delaying cutoff of a voltage is provided in the power supply line for supplying power to an optical module 14 of a transponder unit 16 of each wavelength. The power-down delay unit 15 assigns a different delay in power disconnection each wavelength. The length of the delay is a time required by an AMP unit or longer to change from an ALC mode to an AGC mode. With the configuration, when the power supply for supplying power to the plurality of transponder units 16 becomes faulty and output of a number of wavelengths simultaneously stops, the actual optical signal gradually stops output wavelength by one wavelength. Thereby a nonlinear effect because of going up of a power of an optical signal too much is not occurred, therefore it is able to prevent an undesired influence for a wavelength not to be stopped.
摘要翻译：在用于向每个波长的应答器单元16的光模块14供电的电源线中提供用于延迟电压截止的掉电延迟单元15。断电延迟单元15在每个波长的功率断开中分配不同的延迟。延迟的长度是AMP单元所需的时间或更长从ALC模式变为AGC模式的时间。通过该结构，当用于向多个应答器单元16供电的电源发生故障并且多个波长的输出同时停止时，实际的光信号逐渐将输出波长停止一个波长。因此，不会发生由于光信号的功率过大而引起的非线性效应，因此能够防止对不停止的波长的不期望的影响。

摘要： A power-down delay unit for delaying cutoff of a voltage is provided in a power supply line which supplies electrical power to an optical module of a transponder unit for each optical wavelength. The power-down delay unit assigns different delays for each wavelength. The length of the delay is a time required by an AMP unit to change from an ALC mode to an AGC mode or longer. When the power sources for supplying electrical power to the transponder units becomes faulty and outputs of several wavelengths are simultaneously going to stop, the power-down delay unit delays cutoff of the supply voltage to the optical modules by keeping supply voltage for a while to the optical modules on behalf of power sources enabling the optical modules to operate after the power sources shutdown, so that the actual optical signals gradually stop one by one.
