COMMUNICATIONS COMPONENTS Fused Coupler, Visible Light Key Features • Visible wavelength operation • All fiber — no lens alignment • No unwanted reflections • Low light loss • High power handling Applications • Visible and display systems • Sensors • Biomedical equipment • Research NORTH AMERICA : 800 498-JDSU (5378) The JDSU visible light fused fiber coupler is a compact, low loss, fused component (1x2, 2x2) that is bidirectional and splits or combines visible optical signals. It is designed for use in display systems, test equipment, fiberoptic research, and fiber sensors. The coupler uses advanced fused fiber technology to provide optimum performance at wavelengths within the visible light spectrum. No light leaves the fiber and therefore no alignment is required; and there are no unwanted reflections. Furthermore the output fiber pigtails may be directly integrated into beam delivery systems.
