Optical Module PMD
The PMD plug-in module for the MTS-6000 and MTS-8000 base units works with the fixed polarization filter method (fixed analyzer) standardized by the ITU-T, IEC, and TIA/EIA. Using the PMD module, the PMD runtimes and the PMD coefficient can be measured and the. Measurement devices used to determine chromatic dispersion (CD) and polarization-mode dispersion (PMD). The transmission quality of high-speed optical networks is affected by dispersion. Dispersion refers to the degradation of the transmission signal caused by spectral and polarization effects in.
