DGD-1000 PMD Source General Photonics Datasheet

Product information "DGD-1000 PMD Source"

DGD Range 0-200, 0-44 ps; DGD Resolution 0.2 ps; Single Band C, L, O, Dual Band CL; Max. IL 3.5 dB; Max. PDL 0.3 dB; RL >50 dB

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.
