PMD Emulators

Polarization mode dispersion (PMD) emulator for coherent fiber links (400 Gb/s 80 km ZR, transoceanic links, Tb/s links, …). PMD equalization (with user-supplied control signals). Polarimeters (100 MS/s, memory 64 MS, PDL/PMD/PER measurement).
Speeds up to 20 Mrad/s (or 50 Mrad/s) and N differential group delay (DGD) sections are integrated into one case.
The hardware is optimized for small size and low power consumption, standard: 1RU 19″ rackmount
