Analyzing the BER and optical fiber length performances in OFDM RoF links

Radio over fiber (RoF) can be assessed as a system of most convenient combination optical and radio signals. The technique orthogonal frequency division multiplexing (OFDM) considers data distribution huge number carriers having spaced from each other with specific frequencies at overlap bands. Hence incorporates OFDM the fiber, OFDM-RoF increased modulation RF access capacity besides high-speed transmission, it broadband communication trend current future applications specifically for 5G mobile. network scenarios various model optisystem software, in addition to use section multiplex 16-quadrature amplitude (QAM) modulating signal. In domain, Mach-Zehnder modulator (MZM) modulators are used carry out different results lengths. An wireless advanced rate transmission achievement by minimum delays. essential goal this paper is identifying bit error (BER) 16-QAM varying length. able realizing length 100 km restricted decreasing received power so that constellation noise became greater despite applying electrical amplification amplification.
