Mixed line rate virtual topology design considering nonlinear interferences between amplitude and phase modulated channels

Mixed line rate virtual topology design considering nonlinear interferences between amplitude and... In the last years, the migration from 10 to 40/100 Gbps networks has been proposed as a solution to increase the capacity of transparent optical networks.

Nowadays, some works point out that the deployment of mixed line rate (MLR) networks, where 10 Gbps and higher bit rate Gbps channels share the same fiber, could be more cost effective than the total replacement of 10 Gbps systems. In this paper, we investigate the planning of 10/40 Gbps MLR networks using the ITU 50 GHz grid, considering nonlinear interferences between 10 and 40 Gbps channels, which degrade the quality of transmission.

Abstract

In the last years, the migration from 10 to 40/100 Gbps networks has been proposed as a solution to increase the capacity of transparent optical networks. Initially, the replacement of 10 Gbps legacy equipment was considered. Nowadays, some works point out that the deployment of mixed line rate (MLR) networks, where 10 Gbps and higher bit rate Gbps channels share the same fiber, could be more cost effective than the total replacement of 10 Gbps systems. In this paper, we investigate the planning of 10/40 Gbps MLR networks using the ITU 50 GHz grid, considering nonlinear interferences between 10 and 40 Gbps channels, which degrade the quality of transmission. This approach is novel in the literature. In addition, we conduct a set of tests normalizing the length of fiber links, to observe the trends in MLR planning for different network sizes.
