Abstract

In this investigation, we propose and demonstrate a colorless wavelength division multiplexed passive optical network (WDM-PON) at 2.5 Gb/s using reflective semiconductor optical amplifier (RSOA)-based optical networking units (ONUs); together with a self-protected architecture against fiber fault. In the optical line terminal (OLT), we use an array of self-seeding Fabry-Perot laser diodes (FP-LDs) to provide single-longitudinal-mode (SLM) continuous wave (CW) optical sources for the external injection to the RSOA-based ONUs. The self-survivable function for protecting the fiber fault in the distributed fibers and the proposed network performance are investigated and discussed.

摘要

在本研究中，我们提出并演示了一种基于反射半导体光放大器（RSOA）的光网络单元（ONU）、速率为2.5 Gb/s的无色波分复用无源光网络（WDM-PON）；以及一种针对光纤故障的自保护架构。在光线路终端（OLT）中，我们使用自种子法布里-珀罗激光二极管（FP-LD）阵列来提供单纵模（SLM）连续波（CW）光源，用于向基于RSOA的ONU进行外部注入。研究并讨论了用于保护分布式光纤中光纤故障的自生存功能以及所提出的网络性能。
