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.
