An efficient gain-flattened C-band Erbium-doped fiber amplifier

Abstract

An efficient gain-flattened C-band Erbium-doped fibre amplifier is demonstrated using a double-pass configuration with an IsoGain TM Erbium-doped fibre (EDF). The amplifier utilizes a double-propagation of signal provided by an optical circulator at the output end of the EDF to obtain an improved flatgain characteristic. At input signal power of −10 dBm, a flatgain of 25 dB was obtained from wavelength region from 1528 to 1568 nm. This amplifier has the potential to be used in the high channel count dense wavelength division multiplexing system because of its simplicity and low cost. Gain, dB 28 Noise figure, dB

LabVIEW Applications for Optical Amplifier Automated Measurements, Fiber-Optic Remote Test and Fiber Sensor Systems

“…4.1 Self-calibrating automated characterization system for EDFA Ultrahigh-capacity optical transmission systems are a vital component for 21st-century telecommunications networks that support various expanding information systems such as the Internet, mobile communications, and digital cable television [15].Wavelength-divisionmultiplexing (WDM)systems employing optical amplifiers such as the erbium-dopedfiber amplifier (EDFA) are considered the most effective solution to increase data transmission capacity [16][17]. The main characteristics of EDFAs are their gain and noise figure, and their values depend on the input signal wavelength, input signal power, and pump power [4].…”

Bidirectional-pumped L-band erbium-doped fiber amplifier with pump distribution technique

“…EDFA is the most frequently used and the best known optical amplifier that suits to low loss optical window of silica based fiber. Since the C band (1530-1560 nm) EDFA [4,5] has a limitation in capacity bandwidth, the extension of transmission window has been discovered which is long wavelength band (L band) [6][7][8] that lies from 1570 to 1605 nm. With this transmission window, more inventions have been discovered and thus, the telecommunication bandwidth can be widened up.…”
