| Research Abstract |
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.
