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. POF (plastic optical fiber) data communication High-speed response: 70 MHz Absolute maximum ratings Parameter Reverse voltage Forward current Pulsed forward current*1 Operating temperature Storage temperature Symbol VR IF IFP Topr Tstg Value 3 50 80 -30 to +85 -40 to +100 Unit V mA mA °C °C *1: Pulse width: 1 μs, Duty ratio=50 % Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.
