Optical Transmitter
A driver is fitted in the transmitter. The driver energizes an LED (light-emitting diode).
The LED transmits light signals on the MOST bus (650 Nm light, i.e. red visible light). The repeat frequency is 44.1 MHz.
The sensing frequency on a CD player and for audio is 44.1 MHz; this means than no additional buffer is required, yet another reason why this bus system is so efficient for multi-media.
