针对长距离、高分光比的波分复用/时分复用无源光网络（WDM/TDM-PON）系统，提出了一种高输出功率、高突发消光比的波长可调光网络单元（ONU）发射机。我们的λ-可调谐ONU突发模式发射机（B-Tx）利用一个简单配置的突发模式控制的升压半导体光放大器（SOA），采用增益峰值失谐的模式效应缓解技术。在所有上行波长信道上成功地获得了高输出功率和脉冲消光比，分别超过+10.0 dBm和66.0 dB。这种突发消光比性能满足ONU对64分裂WDM/TDM-PON的要求，串扰损失优于0.1 dB。此外，方向图效应被大大减轻，并且实现了低于0.8dB的40 km传输代价。我们成功地演示了超过41 dB的损耗预算和40 km的波长可调谐WDM/TDM-PON，而无需基于光放大器的PON中继器。
This paper proposes a high output power and high burst extinction ratio wavelength (λ)-tunable optical network unit (ONU) transmitter for long-reach and high-splitting ratio wavelength-division multiplexing and time-division multiplexing passive optical network (WDM/TDM-PON) systems. Our λ-tunable ONU burst-mode transmitter (B-Tx) utilizes a simply configured burst-mode controlled booster semiconductor optical amplifier (SOA) that employs the pattern effect mitigation technique of gain peak detuning. A high output power and burst extinction ratio are successfully achieved at all upstream wavelength channels, over +10.0 dBm and 66.0 dB, respectively. This burst extinction ratio performance satisfies the ONU requirement for a 64-split WDM/TDM-PON with crosstalk penalty of better than under 0.1 dB. Moreover, the pattern effect is greatly mitigated and 40 km transmission penalty of under 0.8 dB is achieved. We successfully demonstrate over a 41 dB loss budget and 40 km reach λ-tunable WDM/TDM-PON without an optical-amplifier-based PON repeater.
