High Gain Erbium Doped Fiber Amplifiers
Performance improvements by using an isolator as an amplified spontaneous emission suppressing component within erbium-doped fibers are evaluated. Simultaneous high-gain and near-quantum-limited noise figures can be obtained by such a scheme. The noise figure improves for input signal powers below -5 dBm and an improvement of 2.0 db with a simultaneous gain increase of 4.1 dB is measured relati...
متن کاملGain, Noise Figure and Efficiency Characteristics of an L-Band Erbium Doped Fiber Amplifier
In this work, the construction of a single stage L-band erbium-doped fiber amplifier which incorporates a short 5.1 m erbium doped fiber coil is described. Gain and noise figure measurements as a function of forward, backward and counter-propagating CW 1480 nm pumping schemes at different pump power levels are presented. Further, the Erbium Doped Fiber Amplifier (EDFA) power conversion efficien...

متن کاملComplete Analysis of Erbium-Doped Fiber Amplifiers Technical Paper
Optical amplifiers make the communication system transparent from the beginning to the end, in contrast to conventional repeater-type systems. This poses new challenges for the performance of all system components, including the optical amplifier. As a consequence, optical amplifiers need to be most thoroughly tested before their deployment. This paper discusses methods and instruments for meas...
