الملخص الإنجليزي

A Radio-over-Fiber (RoF) make use of the advantages of wireless communication system and optical networks.

It uses optical fiber as a core technology due to the enormous advantages offered by it.

Making use of mobility available by wireless communication.

Dispersion management and modulation were investigated for two Channel-WDM optical communication systems.

Dispersion compensating fibers (DCF) are used to compensate the positive dispersion accumulated over a protracted haul SMF between CS (central Site) and BS (Base Station).

The full duplex RoF system is implemented by means of Wavelength Division Multiplexing (WDM) and Optical Add Drop Multiplexer (OADM), where WDM enables transmission of many signals via a single mode fiber for long distance while OADM allows data transmission of both down-link and uplink a by single-mode fiber (SMF).

The modulation technique employed by the proposed system is DPSK.

which has some advantages over binary PSK, like a low phase error rate and no need to know the absolute phase.

The proposed RoF system has been simulated using Opti System 13.0 simulator.

The system outcomes like the Q-factor, and BER with and without (DCF) at different fiber length have been used to discuss system performance.

It has been observed that the proposed system improves the Q-factor by 6-units and the BER by 24 dB at CS and 57dB at BS respectively.
