Abstract

Proposed the inline EDFA-EYCDFA (Erbium Doped Fiber Amplifier - Erbium ytterbium co doped fiber amplifier) with Quad Pumping for multi wavelength services in optical communication systems using WDM technology. The proposed inline EDFA-EYCDFA model simulated by dual forward and backward pumping, dual-backward pumping, Tri-single forward and dual backward pumping and Quad-single forward and tri-backward pumping with respect to Pump power and fiber Length. The parameters Input optical power, output optical power, Gain, Noise figure, Forward noise power and backward noise power measured from all the types of pumping techniques from that the proposed inline EDFA-EYCDFA with Quad pumping gives high strength gain output with less forward noise power and backward noise power. Quad pumping is the best model suitable for multiple wavelength services in optical communication. The Results shown in Quad pumping Gain is maximum 28 dB and Forward Noise power is less -42.9dBm with the pump power of 20dB and fiber Length 5m.
