OZ Optics’ DDL-650-11 differential polarization delay lines represent the next stage in controlling polarization mode dispersion in optical networks. The devices split the light within a fiber into orthogonal polarizations, and then actively vary the time that one polarization travels compared to the other polarization before combining the two polarizations together again.

With this technique, one can introduce up to ±50 ps of optical delay in a system. The resolution of the DDL-650-11 differential polarization delay lines is better than 0.003 ps, thus providing a high degree of control. The devices are easily controlled by a computer via an RS-232 interface. Home and end position sensors allow easy monitoring of the device status and prevent any potential damage to the device.
