“…Optical amplifiers were proposed for amplifying the distorted signal and processing the attenuation problems [5], [6]. The dispersion is caused by pulse broadening of the optical spectrum when the signals are transmitted over a long transmission distance at different speeds and this makes some signals arrive before others [7], [8]. The dispersion compensation fiber (DCF) is an essential technique to reduce the dispersion problem by inserting negative dispersion to make the mean value close to zero [9], [10].…”

Linear and non-linear impairments are the major problems that affected the dense wavelength division multiplexing (DWDM) system performance. In this simulation designs, two different compensation techniques have been proposed to eliminate signal impairments. The repeater technique was proposed to reduce non-linear effects like four-wave mixing (FWM) which cause transfer power from DWDM channels to another new channels. The dispersion compensation fiber (DCF) technique was used to reduce dispersion effects which cause signal pulse broadening over long transmission distances. Also, three different modulation formats and four frequency separations were used to determine which modulation scheme is more compatible with the compensation techniques. The results is calculated in term of quality factor against power and noetic that the carrier suppressed return to zero (CSRZ) format offers the best performance with the DCF technique with 32.1804 Q-factor at 15dBm threshold power then, the differential phase shift keying (DPSK) format is compatible with the repeater technique with 27.7959 quality factor and 14dBm threshold power.

“…Moreover, to the best of the authors' knowledge, there is little research comparing all of these dispersion management approaches for microwave or millimeter-wave analog RoF systems. However, there are various studies comparing the use of DCF and FBG in order to identify the optimum approach that improve the performance of optical fiber system [38,39]. In ref.…”

“…[38], the authors confirmed that the use of DCF, although being more costly to implement than FBG, is a promising approach for improving system performance. The authors in [39] made a comparison between the use of DCF and FBG for three different types of optical modulation in a particular optical system. They found that the use of DCF overcomes FBG for all three types.…”

We present numerical modeling and simulation on the effects of standard single-mode fiber (SSMF) properties and different dispersion management approaches on the distortions of laser diode. These distortions are associated with the two-tone modulation of laser diode for use in radio over fiber systems. The fiber properties include attenuation and dispersion. The dispersion management approaches include the use of nonzero dispersion-shifted fiber (NZ-DSF), fiber Brag grating (FBG), and dispersion-compensating fiber (DCF). The laser is directly modulated with two analog frequencies of 25 and 25.1 GHz at different modulation depths (m). The modulated laser signals are then propagated through SSMF at different lengths (L). The investigated laser signal distortions include the 2nd harmonic distortion (HD2), and the 2nd and 3rd intermodulation distortions (IMD2 and IMD3, respectively). The results reveal that all laser distortions are exacerbated as the fiber length increases, which is mainly due to the chromatic dispersion, while fiber attenuation has no effect. The use of dispersion management approaches gives almost similar effects on the reduction of IMD3 when L = 1 km, regardless of the value of m. Up to m = 0.3, DCF is the most effective approach for reducing all distortions over the entire fiber length range, while NZ-DSF is the least. When L = 2 km, FBG is the most effective approach for reducing both IMD2 and HD2 when m ≥ 0.4, whereas when L is increased to 6 km, DCF is the most effective approach up to m = 0.5.
