PMD-1000 PMD Source

PMD Range 1st Order 0-91, 0.36-182.4 ps, 2nd Order 2,000, 8,100 ps²; PMD Switching Time 1 ms; C-, L-Band; IL 5.0, 5.5 dB; PDL 0.45, 0.5 dB; RL 50 dB

Lunas’ PMD-1000 is a flexible, digital PMD (polarization mode dispersion) source that deterministically generates precise 1st order PMD up to 180 ps and 2nd order PMD up to 8,100 ps2. Its quasi-continuous operation mode enables independent generation of first order and wavelength-independent second order PMD for uniform coverage of the PMD space.

The PMD-1000 uses high-speed ternary magneto optic crystals to generate PMD. The PMD switching time is as short as one millisecond, making the PMD-1000 the fastest PMD generator on the market.

Its automatic polarization controller combined with before and after polarimeters enhances the instrument’s flexibility. For example, if the polarization controller is used to align and maintain the input SOP (state of polarization) at 45° from the principal axis of the DGD (differential group delay) element, the instrument creates the worst-case first order PMD effect.

Alternatively, the controller can adjust and maintain the input SOP using the feedback from the rear polarimeter to either minimize or maximize the output DOP (degree of polarization) for each PMD setting. Minimizing the output DOP enables testing of the worst-case total PMD effect, while maximizing the DOP turns the PMD-1000 into a PMD compensator, allowing the user to obtain optimized PMD values for PMD compensation.

The PMD-1000 can also perform PMD emulation by generating statistical PMD distributions. Finally, the system’s polarization controller and polarimeters enable variable rate scrambling and deterministic polarization control functions, including trace generation and polarization stabilization at any SOP. Lunas’ PMD-1000 makes your PMD-related systems testing simple, fast and professional.
