Channel Allocation Analysis for EDFA-based C+L Optical Systems

Abstract

The channel allocation in a long-haul C+l optical link supported by a parallel EDFA-based amplification subsystem is comparatively analyzed for 80 channels allocated on C, L, or C+ L optical band. The achieved results indicate gains on employing a less dense channel grid fully occupying the C+ L band, resulting in a reduction of linear and nonlinear impairments.
