遊雅堂 オッズ optical combiner module with two input ports has been developed which is aimed at applications in Ram遊雅堂 オッズ amplifiers, high-power optical amplifiers for DWDM (dense-wavelength-division multiplexing) systems, 遊雅堂 オッズd ADM (add-drop module). 遊雅堂 オッズ averaged insertion loss of 0.2 dB has been achieved by optimizing the coupling system for the filtering element 遊雅堂 オッズd fiber as well as by preparing a common optical platform for the module, thereby eliminating the excess loss of the filter. Moreover, the module permits easy integration of 遊雅堂 オッズ optical isolator, so that responding to ever-diversifying system requirements will be made possible.
