Manufactured using a single low loss fusion and available in configurations of 1X3, 3X3, 1X4, or 4X4, these couplers offer low loss optical splitting in a single cylindrical package.
Single fuse couplers, by virtue of their phase properties, are also ideal for use in fiber-optic gyroscopes (FOGs), and are available with ultra-compact housings and ø80 μm cladding fiber pigtails, directly compatible with FOG sensing loops. The low loss offered by our couplers ensures optimal FOG sensitivity. These FOG-optimized single fuse couplers are available on a custom basis. Please contact us for a specification tailored to your requirements.
