Abstract
We propose a 425-Gb/s intensity-modulated direct detection (IM/DD) duo-binary system with 50-GHz channel spacing. Both of the modulator and photodetector (PD) have 10-GHz 3-dB electrical bandwidth. At receiver, least mean square (LMS) algorithm is used to compensate the signal distortion after transmission. After 20-km standard single mode fiber (SSMF) transmission, LMS algorithm improves about 2-dB receive sensitivity at forward error correction (FEC) limit (BER = ) in duo-binary system. With LMS algorithm, duo-binary system has about 5-dB receive sensitivity improvement at FEC limit compared to on-off keying (OOK) system over 20-km SSMF transmission. This paper proposes a feasible scheme for future high-speed passive optical network (PON).
