Abstract

The distance of communications in fiber optics is limited due to the losses in the transmission of the light from the source to the ultimate user. The biggest energy losses occur at the LED (light-emitting diode) and the fiber interface. Mismatch in the geometry and the misalignment of the two results in 12 to 14 dB (decibel) losses.
