Utilizing Self-Seeding RSOA with Faraday Rotator Mirror for Colorless Access Network

Abstract

In this paper, we propose and demonstrate a self-seeding 1.2 GHz RSOA-based laser by employing 3.5 Gbit/s orthogonal-frequency-division-multiplexing quadrature-amplitude-modulation (OFDM-QAM) with bit-loading algorithm for upstream traffic in a colorless WDM-PON access. To achieve 3.5 Gbit/s traffic data rate and accomplish the forward error correction (FEC) threshold [bit error rate (BER) = 3.8x10(-3)], a Faraday rotator mirror (FRM) is used to perform self-seeding operation in this experiment. Here, the power penalty is about 2.59 dB at the wavelength of 1550.0 nm wavelength in a 20 km single mode fiber (SMF) transmission. Moreover, the measured BER performances of proposed laser are also discussed and analyzed, while the fiber mirror (FM) is used to replace the FRM in this experiment.
