In order to fulfill the bandwidth demand, radio over fiber (ROF) communication systems which integrates optical and radio signal is highly promising for satisfy such requirements. So, this work presents a multi-wavelength laser diode for broadcast and communication system applications using a reflective semiconductor optical amplifier (RSOA). In contrast to the previously broadcast transport systems, this broadcast light source free spectral range (FSR) can tunable. Additional, to demonstrate systems performance, which is analyzed pseudo random binary sequence (PRBS) 625Mb/s or orthogonal frequency division multiplexing (OFDM) - quadrature phase shift keying (QPSK) 312.5Mb/s broadcast signal by using bit-error-rate (BER) measurements for back to back (BTB) and 25km fiber transmission. According to the experimental results, excellent performances of BER is achieved for PRBS broadcast signal applications, along with OFDM broadcast signal transmission achieved as well.
