Novel wavelength-routing all-fiber WDM network: implementation and optimization

A novel wavelength-routing all-fiber 10Gb/s WDM network with four nodes in a ring topology is forwarded, and at each node data can be transmitted at different wavelength according to the destined node which it wants to transmit. The main character of the system is that the stable-packed chirp fiber Bragg gratings (CFBG) used in this network utilize two functions: route and dispersion compensation. Meanwhile, a modified measuring method of power penalty including cross-talk penalty, ASE penalty and dispersion penalty is illustrated, and the experiment conducted in this paper shows the measuring method can be perfectly applied in this wavelength-routing all-fiber WDM network system mentioned above. All these measures ensure that optimum system performance would be achieved.
