20 Gbps Bidirectional Transmission via Four Channels over Long-haul SMF in a WDM-PON Architecture using External Modulation Scheme

摘要

A novel architecture of bidirectional gigabit signal transport system over long-haul single-mode fiber (SMF) using wavelength division multiplexed passive optical network technique is proposed and demonstrated. In order to offer multimedia services of high bandwidth, four signals of 5 Gbps data rates are externally modulated and transmitted through four channels over 100-km SMF in uplink and downlink. In our proposed scheme, an excellent bit error rate, good Q-factor and clear eye diagrams are observed for both 100-km uplink and downlink transmission. This architecture has potential to transmit 4x5Gbps over long-haul fiber backbone and it will be useful in future broadband communications.
