RF- and optical-integrated radio-over-fiber (RoF) network with high channel allocation capability

Utilization of unexploited channel spacing provided between two optical channels transporting 10 Gbps data to transmit three RF channels carrying 2 Gbps wireless data at the same time over a standard single mode fiber (SSMF) of 50 km is projected. In this proposed integrated RoF system, the simultaneous transmission of optical- and RF-channels is demonstrated in the pre-installed SSMF infrastructure in conjunction with minimum degradation due to the nonlinearity of the external integrated modulator and the fading problem due to the fiber dispersion. The projected integrated RoF system is experimental with acceptable BER for both the signals and consequently, provided high channel allocation capability.
