The increase in fibre end output power along with the high speed response, 70 MHz for a –3dB drop in signal, and 660nm emitting wavelength mean that altogether the L10762 is an ideal LED to be used for POF data communications networks.
New LED from Hamamatsu for POF Data Communication
Hamamatsu Photonics introduce the new L10762 resonant cavity LED for POF (Plastic Optical Fibre) data communication. The new L10762 is a red emitting resonant cavity LED that offers 7 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.
