DGD-1000 First Order PMD Source/Emulator
⠀⠀⠀⠀⠀⠀⠀⠀⠀
The DGD-1000 is a first order polarization mode dispersion (PMD) source that generates precise amounts of differential group delay (DGD) of up to 400 ps, with no second order PMD.
PRODUCT DESCRIPTION
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. The DGD-1000 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 instrument is available in different versions to accommodate the need for different wavelengths and DGD ranges.
Key Features
- Large DGD range (up to 400 ps)
- Accurate at both low and high DGD values
- Output DGD and and state of polarization (SOP) stable over time
- Output DGD is wavelength insensitive over the specified band
- Very low IL and PDL variability over output DGD range
