Effects of optical repeater lines for reshaping on communication systems

Abstract

Analyses of ideal models for reamplifying and reshaping repeaters are presented to evaluate performance of such lumped repeater chains for long‐haul transmission, compared with EDFA chains. A non‐ideal case in real systems, which is based on interferometric configuration of semiconductor optical amplifiers (SOA), is addressed and measured and its noise characteristics are analyzed. System performance evaluations in a communication line are performed. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:843–848, 2017
