Abstract

Multi-band transmission systems have emerged as a potential answer to the limited capacity of silica based optical fiber. It is based on utilizing the complete low-loss region of optical fibers. Additionally, elastic optical networks (EON) were proposed to efficiently manage limited resources in optical networks. The selection of route, modulation format and spectrum is the main problem that requires solving to operate an EON. Understanding how linear and nonlinear impairments accumulate during propagation in an optical fibre link in essential to solve this problem. Here we preset a study on the maximum reach optical signals can propagate in a multi-band environment for a variety of modulation formats with commonly used threshold values in EON.
