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)传输的用于区域和城域的分布式多载波可复用网络(DMRN)。在传统网络中，为了消除每个接入节点处的多个分布式激光二极管(LD)，由集中式多载波光源(MCL)产生的光载波被分配到接入节点，并用于节点到节点的数据传输。在网络中，我们提出了一种称为光载波再生(OCR)的技术，通过该技术，分布式载波可以在每个接入节点中重复使用。该技术具有简单的方案，并且使我们能够重复使用先前源节点和目的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，并进行了DMRN实验。结果表明，DMRN可用于高传输性能的广域城域网络。

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.
