Proposed the EDFA and EYCDFA power booster
(Erbium Doped Fiber Amplifier- Erbium ytterbium co doped
fiber amplifier) with quad pumping for high speed and multi
wavelength services in an optical communication. The
proposed EDFA and EYCDFA power booster with
WDM(Wavelength division multiplexing) simulated by dual
forward and Backward pumping, Dual-backward pumping,
Tri-single forward and dual backward pumping and Quadsingle forward and tri-backward pumping with respect to
Pump power and fiber Length. The parameters Input Optical
power, Output Optical power, Forward Signal power,
Backward Signal power measured and determined the speed of
transmission in all types of pumping methods. From that the
proposed EDFA- ans EYCDFA power booster with WDM
quad pumping is the best suitable for secured high speed
optical telecommunication systems. The results shown in Quad
pumping Output optical power is maximum 25.2dB and
optimum spectral forward Signal power is 30.5dBm and very
less spectral optical backward signal power of -25.4dBm with
Length 5m
