The performance of radio-over-fiber (ROF) optical transmission and wireless transmission of ultrawideband (UWB) system administrations is described when operating in the underwater communication. In order to increase the coverage and enhance channel efficiency, ROF system which employs subcarrier multiplexing (SCM) and dense wavelength-division multiplexing (DWDM) is used. DWDM provides efficient channel with tapered channel spacing, whereas SCM's unique commonality helps in achieving high mobility and large bitrates. The performance of dual-carrier modulation orthogonal frequency-division multiplexing is compared with other modulation techniques, and to indicate an exchange between bit error ration and throughput for the system, our work investigates the punctured turbo coding. For 6 dB Eb/No value, a maximum of 1120 Mbps throughput per band can be accomplished in comparison with 480 Mbps per band of the orthogonal frequency-division multiplexing UWB. To modulate and to develop code designs for a rational UWB-ROF and wireless system in underwater communication with VLC, the proposed study provides a reliable solution.

“…One is the direct modulation of laser light, that is internal modulation, and the other is external modulation using the external devices such as the electro-optic modulator. [13][14][15] The internal modulation is to inject the optical source into the transmitting signal to get the modulation signal. This method has many advantages, such as simple structure, low loss, economic and easy to implement, etc.…”

Ultra-Wide Band radio-over-fiber (UWBoF) technology involves two kinds of communications. One is the UWB wireless communication, and the other is optical fiber communication. In this paper, the UWBoF receiving system based on the external modulation such as Mach-Zehnder (M-Z) modulator is analyzed. The UWBoF components and the UWBoF receiver structure are introduced. The received high frequency UWB signal by UWB antenna has been transformed into the low frequency which could be fit the frequency requirement for the RF port of the M-Z modulator. The electronic signal can be transformed into the optical signal and transmit in optical fiber by M-Z modulator. Firstly, the characteristics of M-Z modulation are analyzed in theory. Then the half-wave voltage and the modulation output spectrums characteristics of the UWBoF receiving system have been tested. The testing results show that the output spectrums characteristics are consistent with the theoretical analysis.
