SINGLE FUSE COUPLER 1X3, 3X3, 1X4, 4X4
Fused Fiber Coupler
The single fuse coupler provides optical splitting and combining for >2 ports. A single low loss fusion takes place to produce 1x3, 3x3, 1x4 and 4x4 couplers in a cylindrical package.
Standard versions of these components are available optimised for 980 nm, 1310 nm, 1480 nm, 1550 nm or 1585 nm wavelengths. These may be used in a wide variety of applications including optical network expansion.
Single fuse couplers by virtue of their phase properties, are also ideal for use in fiber Gyros. Versions are available with ultra-compact housings and ø80µm cladding fiber pigtails, directly compatible with Gyro sensing loops. Low loss ensures optimal Gyro sensitivity.
These Gyro-optimised single fuse couplers are available on a custom basis. Please contact us for a specification tailored to your requirements.
