Single Fuse Coupler 1x3, 3x3, 1x4, 4x4

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 single cylindrical package.

Standard versions of these components are available optimised for 980, 1310, 1480, 1550 or 1585nm 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 fibre gyros. Versions are available with ultra-compact housings and ∅80μm cladding fibre pigtails, directly compatible with gyro sensing loops. Low loss ensures optimal gyro sensitivity.
