An electrical-to-optical (E/O) converter isolates the signal and converts it to an optical analogue. An optical-to-electrical (O/E) converter demodulates the optical signal to an electrical signal whose common mode elements have been rejected. The E/O converter uses a low-contact DC to DC converter as a power source to provide a high degree of isolation. | An electrical-to-optical (E/O) converter isolates the signal and converts it to an optical analogue.
