Red LED
L10762
Resonant cavity LED for POF data communication
The L10762 is a red LED designed for POF data communications. A microball lens is bonded to the LED chip to enhance fibrecoupling efficiency.
Features
Applications
Improved fiber-coupling efficiency
A microball lens is bonded to the LED chip surface to
enhance the coupling efficiency to optical fibers.
Fiber end output power *2 was boosted about 7 times
higher than our conventional type.
