Hamamatsu Photonics introduced the L10762 resonant cavity LED for POF (plastic optical fibre) data communication.
The device is a red emitting resonant cavity LED that offers seven times the fibre end output power compared to conventional types; this is achieved by bonding a microball lens to the LED chip surface. The microball lens greatly increases the coupling efficiency to optical fibres by focusing the emitted light into the fibre.
The increase in fibre end output power along with the high-speed response – 70 MHz for a –3 dB drop in signal – and 660 nm emitting wavelength mean that the L10762 is ideally suited for use in any POF data communications network.
