OZ Optics now offers polarization maintaining fiber optic switches. These switches are built using polarization maintaining (PM) fiber and maintain polarization to better than 20dB on both channels, while providing less than 0.6 dB losses. The switches have been tested over millions of switching cycles with no change in losses or polarization performance. These switches are ideal for next generation high-speed networks, thanks to the use of PM fiber to eliminate PMD and PDL issues. They are also ideal for test instruments that use PM fibers to make measurements. Singlemode fiber versions are also available.
