Gain, 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 کاملErbium Doped Fiber Amplifiers: State Of Art
The field of optics has a drastic impact in the field of electronics and communication. With the rising need for higher data transfer rate, optical advancements have served this purpose. Optical amplifiers play a crucial role in the amplification of signal at regular intervals to avoid loss of data. Erbium doped fiber amplifiers (Erbium Doped Fiber Amplifier) carry out the amplification by stim...
متن کاملHigh 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 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...
