Investigate 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 کاملOptimum 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 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 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 کاملOptical Amplifier Options for Wideband Submarine Systems
The main wideband amplifier candidates for use in submarine systems are hybrid DRA/EDFA and C+L band EDFAs. We explore the relative merits of the two technologies and demonstrate through simulations that the hybrid approach is advantageous for most systems. Introduction Submarine systems have enjoyed the tremendous advances in coherent transmission brought about by high speed DSP technology ove...
