REAM intensity modulator-enabled colorless transmission of real-time optical OFDM signals for WDM-PONs

Reflective electro-absorption modulators are, for the first time, incorporated in real-time optical OFDM (OOFDM) transceivers with online adaptive bit and power loading. Colorless OOFDM transmissions of 10.5Gb/s over 25km SSMF in simple IMDD systems are experimentally demonstrated with >5dB improved receiver sensitivities compared to RSOAs.
