Short Wavelength Singlemode 1X2 & 2X2 Fiber Optic Couplers & Optical Splitters


   Gould's short wavelength singlemode Fiber Optic couplers & Optical Splitters are small in size and offer low optical loss and minimal reflection for noise sensitive systems. These devices are well-suited for sensor applications, duplex transmission on a single fiber, and small percentage power taps.
