The Fiber-Fiber^s Series of optical switch is based on a patented MEMS 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, as well as reflections from internal surfaces .  It offers unparalleled advantages of a nearly lossless low loss of about 0.2dB for all ports (below 0.01dB with special order),   broad wavelength operation from 200nm-4000nm, little back-reflection, amicable to any fiber types, vibration insensitive, 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 8 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/testing systems, spectroscopy (including Raman and fluorescence), industrial production and process control, telecommunications, as well as in the biomedical.
