LUNA DGD-1000 – First Order PMD Source/Emulator
- The DGD-1000 can generate DGD up to 400ps
- DGD-1000 has very low PDL over DGD generation range (PDL max: 0.3dB, typical: 0.1dB)
- DGD-1000 has very low IL variation over DGD range (typical 0.1dB)
- Slow SOP variation (<1 rad/min)
- Small DGD variation vs time (<0.1ps over 8 hours)
- An extended version can cover up to 600ps as special order
Polarisation 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 LUNA 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. This instrument is available in different versions to accommodate the need for different wavelengths and DGD ranges.
