Product Introduction FOG optical module is a modular component of Fiber Coil + MIOC designed for fiber optic gyros. The fiber coil and MIOC are spliced together and integrated in a shell. The FOG optical module can be treated as an independent integrated sensing component, and the users no longer need expensive PM fiber fusion splicer to splice PM fibers of fiber coil and MIOC. Product Features Fiber coil + MIOC Compact and easy to assemble High precision and reliability Cost
