An optical add-drop filtersystem is used togenerate ultra-short nanometer (nm) bandwidth soliton
pulses to be transmitted along the nano communication nonlinear fiber optics. In order to reduce the
loss during the transmission, ultra-short soliton pulses are recommended. The theoretical part of this
study uses theZ-transform method to present the characteristic transmission of the optical add-drop
filter system. Thenonlinear refractive index of the fiber optic transmission link is 26×10
−20m2
/W.
The Wavelength Division Multiplexing (WDM) can be performed to enhance the capacity of the
system. This occurs when the bigger size of the ring resonator is used. Here, soliton pulses with
bandwidths of 2.1 and 0.42 nm are generated and transmitted over the fiber optic length, where
signals with a bandwidth of 55 and 200 ps are successfully detected at the end of the transmission
link.
