Gould's Wavelength Independent fiber optic Coupler (WIC) can be used to split light from one fiber to two or combine light from two fibers to one and provide high performance across a broad wavelength region (from 1270nm to 1600nm). WIC couplers are ideal from use in two color OTDRs, full duplex transmission on a single fiber, multicolor sensors, and trunk/loop branching. These small devices are insensitive to the operating wavelength and provide low optical loss with high directivity.
