The modulator acts as a polarizer and provides signal dithering to improve the detection sensitivity, while the LED is used as a channel sensor. The channel sensor can monitor a wide wavelength range that is rapidly adjustable and can have much relaxed tolerance on temperature control. The combination of a polarization controller/rotator and the polarized modulator can accurately measure the OSNR between 5 and 35 dB with an error less than 0.5 dB. |
