Analysis of OSNR monitoring in optical fiber communication system

Abstract

The transmission data rates of the next generation intelligent optical networks are high, and the applications of dense wavelength division multiplexing (DWDM) and reconfigurable optical add-drop multiplexer (ROADM) enable the traditional out-band optical signal-to-noise ratio (OSNR) monitoring techniques aren't suitable. In this paper, three methods of out… (More)
