Research on photonic networks based on optical carrier regeneration

在这项工作中，我们展示了一种基于密集波分复用（DWDM）传输的区域和城域分布式多载波可复用网络（DMRN）。为了消除传统网络中每个接入节点上存在多个分布式激光二极管（ld）的问题，采用集中式多载波光源（MCLS）产生的光载波分布在接入节点上，用于节点到节点的数据传输。在网络中，我们提出了光载波再生（OCR）技术，即分布式载波可以在每个接入节点上重复使用。该技术方案简单，使我们能够重用先前源节点和目标节点之间已经用于数据传输的载波。我们对所提出的DMRN的可扩展性进行了数值分析，并演示了一个DMRN实验。结果表明，DMRN在广域城域网中具有较高的传输性能。

In this work, we demonstrate a distributed multicarrier reusable network (DMRN) for regional and metro areas, based on dense wavelength-division multiplexing (DWDM) transmission. To eliminate the multiple distributed laser-diodes (LDs) at each access node in conventional networks, optical carriers generated by a centralized multicarrier light source (MCLS) are distributed to the access nodes, and they are used for node-to-node data transmission. in the network, we proposed a technique called optical carrier regeneration (OCR), whereby the distributed carriers can be reused in each access node. This technique has a simple scheme and enables us to reuse the carriers that were already utilized for data transmission between prior source and destination nodes. We numerically analyze the scalability of our proposed DMRN and demonstrated a DMRN experiment. The results show that the DMRN will be useful for wide-area metro networks with high transmission performances.
