Ultra Wide Band Radio DWDM rings with photonic UWB pulse generation and transmission in presence of non-linearities

We have presented a method for optical generation of doublet and triplet and presented a complete DWDM ring on single fiber with UWB generation for uplink signal. This UWB system can support 3 rings. Optical Add Drop Multiplexers are used at each UWB node to drop and insert the required wavelengths. Simulation of Self-phase modulation is done to study the effects on UWB transmission and method has been proposed to minimize the effects.
