Many problems in communication systems can be solved by controlling the center wavelength on Nano fiber ring performance using promising systems. We present the effect of the center wavelength to expanding the free spectrum range (FSR) where the aim is on the finesse improvement. The finesse exponentially proportions with the coupling coefficient. The results show that the free spectrum range (FSR) expand by increasing the center wavelengths of the soliton bands. This is obtained via the add/drop filter, which can be used to increase the channel capacity in the communication network. The controlled FSR and spectral width are ۱۴ nm and ۱۰۰ pm, respectively. This result allows the channel capacity expanding due to the plentiful propagation spacing from the soliton collision
