    An all-optical OFDM system can be implemented.Various techniques have been discussed related to this area.My question is :Can we implement this all-optical OFDM in radio over fiber.Basically in RoF light is modulated using RF,currently most commonly used optical modulator is machzehndermodulator.Now if we are using MZM ,can we employ all-optical OFDM to that particaular RoF,b'coz MZM requires one electrical input and basically in normal OFDM-RoF system the inputs to MZM are light and OFDM modulated electrical signal.
