Fused Single Mode Wavelength Independent (Dual Band/Window) 1X2 and 2X2 Fiber Optic Couplers (WICs) & Optical Signal Splitters

Gould's Single Mode Wavelength Independent (dual window /dual band) 1X2 and 2X2 fiber optic couplers (WICs) & optical splitters 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, multi-color sensors, and trunk/loop branching. These small devices are insensitive to the operating wavelength and provide low optical loss with high directivity.
