Gould’s Fused fiber Wavelength Combiners are made of single-mode or polarization maintaining (PM) optical fibers enabling MUX/DEMUX function for any two, three or four wavelengths in the red, green, blue and violet (RGB/RGBV) spectrum.The Truly Fused multimode Power & Pump Combiners provide very high coupling efficiency over a wide wavelength range from multiple sources into one output fiber. Gould’s Proprietary Fusion process offers very high coupling efficiency, high power handling, zero-alignment and low insertion loss and back reflection. Gould supplies custom, high reliability modules and solution for telecommunications, government, military, sensor/aerospace applications. ISO 9001-2008 Certified and ITAR Compliant.
