| Abstract: | A multi-channel digital variable optical attenuator(VOA) module based on electronic VOA(EVOA) was designed,which integrated with 32 channels VOA and combined with I 2 C interface,so it could be configured flexibly and applied to system devices simply.The module not only overcomed the EVOA's shortage of non-linear of voltage and attenuation,and could be used to perform accurate attenuation,but kept the optical characteristics of EVOA. |
