The Fiber-FiberTM Series of optical switch is based on a patent-pending micro-mechanical technology that self-aligns a fiber directly to another fiber with a tiny gap that is filled with an index-matching liquid. The breakthrough technology enables light propagates in a continuous medium without interruptions, consequently eliminating the need for lenses and AR coating. It offers unparalleled advantages of a very low loss of about 0.3dB for all ports, broad wavelength operation from 200nm-4000nm, little back-reflection, amicable to any fiber types, and high optical power handling. It is also the lowest cost solution in the industry. We offer two platforms: MEMS for fiber count up to 12 and motor-driven for large fiber port count up to 300. The Fiber-Fiber TM optical switches have a broad customer base ranging from optical measurements/test systems telecommunications, spectroscopy (including Raman and fluorescence), industrial production and process control, telecommunications, as well as in the biomedical.
