“…Unfortunately, such approach uses broader wavelength band for transmission. The amplification band of conventional erbium-doped fiber amplifiers (EDFA), that are used in modern transmission systems, is highly limited (1530 nm-1562 nm), and at some point EDFAs will not be able to ensure gain over the whole wavelength band used for transmission in such systems [4], [5]. Manuscript This fact raises a need to find an alternative solution to conventional EDFAs for all-optical signal amplification.…”

Raman amplifiers and Fiber optical parametric amplifiers (FOPA) are positioned as the main future leading techniques for all-optical signal amplification. Distributed Raman amplifiers are known as the least noisy, but this type of amplifiers suffers from poor pumping efficiency at low input signal powers, therefore, discrete (lumped) Raman amplifiers (LRA) could be used instead. Both FOPAs and LRAs are the likeliest replacements of conventional EDFAs, but at this point it is not clear which of these two approaches is the most promising taking into account the quality of the amplified signal. Therefore, the goal of this article is to determine which of the two amplification techniques ensures less amplifier produced signal impairments in a 16-channel 10 Gbps dense wavelength division multiplexed (DWDM) transmission system. Index Terms-Fiber optical parametric amplifier; Discrete Raman amplifier; Wavelength division multiplexing; Interchannel crosstalk.

“…Various techniques have been proposed to extend the band and flatten the gain and expand the DWDM amplification window. These studies attempted to widen the amplification band as broad as possible . Focusing on high and flatten gain and lower noise figure is the target of most research work in the EDFA amplifier topic.…”

A novel design of high and broad gain that covers C and L bands is demonstrated experimentally. The techniques, used in this paper, combine two double pass with split band structure. The signals travel in separate paths after being splitted using a coupler band splitter. The topology of this new configuration uses this technique to broaden the gain at its maximum range of amplification. The presented paper is to study the performance of the augmented gain of the EDFA configuration using what it can be called double pass wide band amplification. The results show a broadening range of 80 nm between 1520 nm and 1600 nm in the C and L band and high gain of 45 dB for the range 1525 nm and 1580 nm and lower gain for the range 1580 nm and 1600 nm. © 2016 Wiley Periodicals, Inc.
