Polarization mode dispersion (PMD) can seriously degrade the quality of high-speed fiber-optic data transmission. High-speed transceivers must meet stringent standards for PMD tolerance.
General Photonics’ DGD-1000 PMD Source/Emulator accurately and repeatably generates both high and low values of differential group delay (DGD) or first-order PMD. Both the DGD and PDL are very stable over time and wavelength within the performance band.
The DGD-1000 PMD source/emulator is available in different versions to accommodate the need for different wavelengths and DGD ranges.
