Optimum Pumping Configuration for L-band EDFA incorporating Selective Wavelength Auxiliary ASE from C-band EDFA
We present a thorough investigation of the optimum pumping configuration for L-band EDFA in order to maximize signal gain and minimize noise figure with forward and backward ASE pumping, by incorporating the selective property of the pump wavelength band from C-band EDFA section. A simulation of three-level rate equation has been carried out using 980 nm primary pump, 1570 nm as Lband signal wa...
متن کامل55 dB High Gain L-Band EDFA Utilizing Single Pump Source
In this paper, we experimentally investigate the performance of an efficient high gain triple-pass L-band ErbiumDoped Fiber (EDF) amplifier structure with a single pump source. The amplifier gain and noise figure variation with EDF pump power, input signal power and wavelengths have been investigated. The generated backward Amplified Spontaneous Emission (ASE) noise of the first amplifier stage...
متن کاملGain Flattening and Noise Figure Analysis of a Dual Stage Bowtie WDM EDFA Configuration in C-Band
The paper presents an improved gain flattening and noise figure analysis in the C-band regime using an equalization filter of a dual stage single mode polarization maintaining bowtie erbium doped fiber amplifier. The configuration uses two in-line 980nm laser pumps. The gain and noise figure variation with fiber length, pump power and temperature of the system for C-band communication have been...
متن کاملInvestigate C+L Band EDFA/Raman Amplifiers by Using the Same Pump Lasers
A hybrid C+L band erbium-doped fiber amplifier/Raman fiber amplifier (EDFA/RFA) is constructed by sharing common 1480 nm pump source(s). It is based on three-level amplification mechanism in the C band and Raman shift amplification mechanism the in L band, respectively. The gain spectra of C+L band are flattened by optimally dividing the pump power ratio of 1:29 for EDFA/RFA. Gain variation is ...
متن کامل[ME01] An Efficient and Low Noise L-band Erbium-Doped Fiber Amplifier
Introduction The use of the long-wavelength-band (Lband) is attractive for both increasing the capacity of wavelength division multiplexing (WDM) systems and has been used in WDM transmission experiments at over 1 Tb/s. Recently, a gain bandwidth of about 80nm has been achieved by integrating the L-band EDFA in parallel with conventional band (Cband) EDFA [1]. Moreover, the L-band EDFAs will ma...
