The utilization of Ultra-wide band (UWB) technology in medical services provides patients with enhanced mobility, that make UWB very important technique in medical area such as medical monitoring for Patient, and medical imaging. Therefore, in this paper we introduce a new technique called optical phase conjugation (OPC) devices that used along the optical link as a new method for improving the performance of wireless medical communications using all optical UWB signal. A 50 GHz spaced two-channel dense wavelength division multiplexing (DWDM) communication system is considered using 360 km single mode fiber (SMF) link with two pumps. Simulation results are compared with the case of without using compensation technique showing better performance in terms of achievable Q-factor, BER performance, and the total length of transmission link.
