“…Dispersioncompensating fiber shows relatively high Raman amplification [41]. DCF has raised germanium content and therefore a somewhat higher loss coefficient than SMF: a fiber loss of 0.55 dB/km for the DCF has been measured.…”

This work is meant to provide a review of different multiplexing topologies employing distributed erbium-doped fiber and Raman amplification to solve the problem of powerloss compensation in fiber-optic sensor (FOS) networks. This is a key parameter in large multiplexing networks, particularly when employing intensity-modulated sensors. These topologies are studied both theoretically and experimentally, and a comparative analysis is carried out between them. The main parameters considered in the analysis are power budget, optical signal-tonoise ratios, scalability and architecture complexity.Comparison of the measured optical spectrum of amplified single and double bus networks for sensor multiplexing.

“…Both schemes, however, require thorough optimisation due to impact of nonlinear effects, sophisticated design, and high sensitivity to environmental perturbations. Amano et al [109] suggested using a highly nonlinear Raman fibre with a nonlinear coefficient of 6.7 W -1 km -1 combined with a dispersion compensation fibre (DCF). This highly nonlinear fibre provides an efficient pump conversion while the DCF compensates for the nonlinear distortion added to the signal.…”

Semiconductor disk lasers offer a unique combination of characteristics that are particularly attractive for pumping Raman lasers and amplifiers. The advantages of disk lasers include a low relative noise intensity (-150 dB Hz -1 ), scalable (on the order of several watts) output power, and nearly diffraction-limited beam quality resulting in a high (~70 % -90 %) coupling efficiency into a single-mode fibre. Using this technology, low-noise fibre Raman amplifiers operating at 1.3 mm in co-propagation configuration are developed. A hybrid Raman-bismuth doped fibre amplifier is proposed to further increase the pump conversion efficiency. The possibility of fabricating mode-locked picosecond fibre lasers operating under both normal and anomalous dispersion is shown experimentally. We demonstrate the operation of 1.38-mm and 1.6-mm passively mode-locked Raman fibre lasers pumped by 1.29-mm and 1.48-mm semiconductor disk lasers and producing 1.97-and 2.7-ps pulses, respectively. Using a picosecond semiconductor disk laser amplified with an ytterbium-erbium fibre amplifier, the supercontinuum generation spanning from 1.35 mm to 2 mm is achieved with an average power of 3.5 W.

“…1(b). Dispersion compensating fiber shows relatively high Raman amplification, however, the low power conversion efficiency is considered to be a major difficulty that must be overcome [9]. In order to enhance the gain of the Raman amplifier, we have proposed highly nonlinear fiber (HNLF) with a Raman gain coefficient of 2.2 W -1 km -1 and attenuation of lower than 0.4 dB/km around 1550 nm.…”
