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.
