This kind of micro mechanical optic switch is driven by a relay to control the prism to turn, thus switch the path, with only few channels such as 1x1,1x2, and2x2. It is normally used for OLP (Optical Fiber Line Protection) system. We offer optical switches with integrated MEMS technology, optical switch kits, and PRO8 modules for fiber-optic circuit integration or construction. A selection of high damage threshold, acousto-optic Q-switches is available. Also available are. Their compact design offers a very low size and lower cost than standard switches. Nevertheless, it has slower speed and larger wavelength dependent loss than the SW or SL types. FTBx-9160 switches deliver quality performance in a compact modular format.
