Home / Backlight current of optical transmitter
An optical transmitter acts as the interface between the electrical and optical domains by con-verting electrical signals to optical signals.
In fact, optical transmitters and receivers are not linear devices but "square law" devices; that is, the instantaneous light output power of a transmitter is proportional to the input current and thus to the
