Modified 1.28 Tbit/s (32 × 4 × 10 Gbit/s) absolute polar duty cycle division multiplexing-WDM transmission over 320 km standard single mode fiber

Abstract

A new version of Absolute Polar Duty Cycle Division Multiplexing transmission scheme over Wavelength Division Multiplexing system is proposed. We modeled and analyzed a method to improve the performance of AP-DCDM over WDM system by using Dual-Drive Mach-Zehnder-Modulator (DD-MZM). Almost 4.1 dB improvement in receiver sensitivity of 1.28 Tbit/s (32 × 40 Gbit/s) AP-DCDM-WDM over 320 km fiber is achieved by optimizing the bias voltage in DD-MZM. © 2011 Springer Science+Business Media B.V.
