摘要： An optical node apparatus according to the present invention amplifies a WDM signal light input to an input port, and thereafter, branches the amplified WDM signal light by an optical branching coupler to send the branched lights to first and second optical paths, and selects the light propagated through the first optical path by an optical switch to amplify the selected light by a post-amplifier, thereby outputting the amplified light from an output port, when the optical node apparatus is operated as an optical amplification repeating node. When the operational state is upgraded to an optical add/drop multiplexing node, an OADM section is connected between a set of connecting ports on the second optical path, and the adjustment of the OADM section is performed utilizing the WDM signal light branched by the optical branching coupler, and thereafter, the switching of the optical switch is performed to select the light on the second optical path side. As a result, since the switching the operational state from the optical amplification repeating node to the OADM node can be performed in a short time, it becomes possible to provide the continued communication service at the low initial installation cost.

摘要： In an optical amplifier of the invention, a first variable optical attenuator is provided between a fore-stage optical amplification unit and a post-stage optical amplification unit, and a second variable optical attenuator is also provided on the output side of the post-stage optical amplification unit. When a signal light input level of a WDM light inputted to an input port is lower than a base point level, an attenuation amount of the first variable optical attenuator is not increased (basically minimized), and the control which increases the attenuation amount of the second variable optical attenuator is performed corresponding to the increase in signal light input level. On the other hand, when the signal light input level is higher than the base point level, the attenuation amounts of both the first variable optical attenuator and the second variable optical attenuator are controlled according to the signal light input level. Accordingly, a low-cost WDM optical amplifier having a wide input dynamic range, in which a predetermined signal light output level and flatness of output wavelength characteristics can be kept by the simple control with respect to a fluctuation in signal light input level, can be provided.
