Abstract :
In this paper, two different configurations to drive multi-services OFDM signals in a dual electrode Mach-Zehnder modulator (DEMZM) to generate an optical hybrid signal (OHS) are investigated. The linearity of the configurations and their performance in the transmission of an OHS composed by a custom 4-quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) gigabit Ethernet (GbE) signal, a 20 MHz quadrature phase shift keying (QPSK) Long Term Evolution (LTE) signal and three OFDM-ultra-wideband (UWB) signals of the first group of the ECMA-386 standard are compared.
