Abstract

We demonstrate 200 Gb/s bidirectional coherent PON solutions using a simplified optical network unit (ONU) over 19 km of field-installed fiber. The ONU receiver is a single-polarization heterodyne detector with either a balanced or a single-ended photodetector and the transmitter is based on dual-polarization electro-absorption modulated laser (EML). The optical line terminal (OLT) uses standard dual-polarization coherent transceivers. The downstream solutions achieve 37 dB and 30.5 dB power budget for the receiver with balanced and single-ended photodiodes, respectively. For the upstream, two line rates have been investigated: 200 Gb/s/

$\lambda $

for symmetrical transmission and 100 Gb/s/

$\lambda $

for asymmetric transmission achieving a power budget of 30.1 dB and 40.9 dB respectively.

通过现场安装光纤演示 200 Gb/s/λ 双向相干 PON 解决方案

我们利用简化的光网络单元（ONU）在 19 千米的现场安装光纤上演示了 200 Gb/s 双向相干 PON 解决方案。ONU 接收器是带有平衡或单端光电探测器的单极化外差探测器，发射器则基于双极化电吸收调制激光器（EML）。光线路终端（OLT）使用标准的双偏振相干收发器。下游解决方案采用平衡和单端光电二极管，接收器的功率预算分别为 37 dB 和 30.5 dB。对于上行，研究了两种线路速率：对称传输为 200 Gb/s/$\lambda$，非对称传输为 100 Gb/s/$\lambda$，功率预算分别为 30.1 dB 和 40.9 dB。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
