The proposed emulator could vary the PDL values simply by adjusting the bias voltage of modulator. The results show that the proposed PDL emulator could generate a wide range of PDL values (0 ~ 35 dB). The generated PDL value could be maintained within ±0.02 dB for >70 minutes. The wavelength dependency was about 0.03 dB in the range of 1520 nm~ 1590 nm.展开更多
