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 fibre-
coupling efficiency.
Features
Applications
Improved fiber-coupling efficiency
POF (plastic optical fiber) data communication
A microball lens is bonded to the LED chip surface to en-
hance the coupling efficiency to optical fibers.
Fiber end output power *2 was boosted about 7 times
higher than our conventional type.
High-speed response: 70 MHz
