WELWYN GARDEN CITY, England, July 19, 2010 — Hamamatsu Photonics UK Ltd. has introduced the L10762 resonant cavity LED for plastic optical fiber (POF) data communications. The company says that the red-emitting resonant cavity LED offers seven times the fiber end output power compared to conventional types. This is achieved by bonding a microball lens to the LED chip surface, greatly increasing the coupling efficiency to optical fibers by focusing the emitted light into the fiber. The increase in fiber end output power, the high-speed response of 70 MHz for a -3 dB drop in signal, and the 660-nm emitting wavelength make the LED suitable for use in POF data communications networks. Features include reverse voltage of 3 V, forward current of 50 mA, pulsed forward current of 80 mA and an operating temperature range of -30 to 85 °C. Typical fiber end output is 1 mW, typical forward voltage is 1.9 V, and maximum reverse current is 10 µA.
