Red LED
Resonant cavity LED for POF data communication
L10762
The L10762 is a red LED designed for POF data communications. A microball lens is bonded to the LED chip to enhance bre-
coupling efciency.

Features
Applications
Improved ber-coupling efciency
A microball lens is bonded to the LED chip surface to en-
hance the coupling efciency to optical bers.
Fiber end output power *2 was boosted about 7 times
higher than our conventional type.
High-speed response: 70 MHz
