MWS DRIFT FEEDBACK COMPENSATOR USING VOA AND INPUT POWER DITHERING |
| 摘要 |
The invention relates to a compensator of attenuation drift in an optical multi-wavelength switch (MWS) which uses input signal amplitude dither and external VOA dither cancellation to determine relative position of MEMS micro mirror hence indirectly determining attenuation level.
