COMMUNICATIONS COMPONENTS Fused Coupler, Near Infrared Key Features • 700 to 1150 nm operation • Available in any coupling ratio • All fiber — no lens alignment • No unwanted reflections • Low light loss • High power handling Applications • Fiber lasers • Sensors • Avionics • Biomedical equipment • Research NORTH AMERICA : 800 498-JDSU (5378) The JDSU near infrared fused coupler splits or combines light at any selected wavelength from 700 to 1150 nm. Designed for applications in fiber laser, sensor and avionics applications, the coupler utilizes low loss fused fiber technology. 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.
