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
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.
