Abstract: As orthogonal frequency division multiplexing (OFDM) has unique advantages, it has been widely used in radio communications. In recent years, OFDM has been introduced into optical communications. Until now, studies of optical orthogonal frequency division multiplexing (OOFDM) are mainly concentrated on
offline experimental analysis and based on real-time analysis with the global clock. This paper demonstrates a high-speed real-time optical OFDM transceiver system based on asynchronous clock transmitting 2.5 Gbit/s 16-QAM-encoded OOFDM signals over 25 km standard single-mode fiber (SMF). The bit error rate is less than 1.2×10−5.

Key words: asynchronous clock, bit error rate, optical orthogonal frequency division multiplexing (OOFDM)
