Observation of Raman Gain in Reduced Length of Bismuth Erbium Doped Fiber
Raman amplification of a 49 cm Bismuth oxide (Bi2O3) as a nonlinear gainmedium based erbium doped fiber amplifier (EDFA) is reported in new and compactdesign in near infrared spectral regions. The bismuth glass host provides theopportunity to be doped heavily with erbium ions to allow a compact optical gain fiberamplifier design by using reduced fiber length and the 1480...
متن کاملKerr nonlinearity mitigation in 5 × 28-GBd PDM 16-QAM signal transmission over a dispersion-uncompensated link with backward-pumped distributed Raman amplification.
We present experimental and numerical investigations of Kerr nonlinearity compensation in a 400-km standard single-mode fiber link with distributed Raman amplification with backward pumping. A dual-pump polarization-independent fiber-based optical parametric amplifier is used for mid-link spectral inversion of 5 × 28-GBd polarization-multiplexed 16-QAM signals. Signal quality factor (Q-factor) ...
متن کاملTechnical Report 03-EMIS-01 Practical Integrated Design Strategies for Opaque and All- Optical DWDM Networks: Optimization Models and Solution Procedures
Dense wavelength division multiplexing (DWDM) networks that use expensive optical/electrical/optical (O/E/O) conversion at each end of a fiber link are called opaque networks. In an attempt to reduce the O/E/O conversion cost component, a combination of technological advances has been used. Improved optical amplifiers using distributed Raman amplification allow signals to traverse longer distan...
متن کاملImpact of Dispersion Fluctuations on 40-Gb/s Dispersion-Managed Lightwave Systems
We study numerically the impact of random dispersion fluctuations on the performance of 40-Gb/s dispersion-managed lightwave systems designed using either the chirped return-to-zero or the soliton format and employing backward-pumped distributed Raman amplification. We consider two-section dispersion maps with 2 = 4 and 8 ps km and show that the parameter decreases rapidly in both cases as the ...
متن کاملPractical Integrated Design Strategies for Opaque and All-Optical DWDM Networks: Optimization Models and Solution Procedures
Dense wavelength division multiplexing (DWDM) opaque networks use expensive optical/electrical/optical (O/E/O) conversion at each end of a fiber link. Several technological advances have been used in an attempt to reduce the O/E/O conversion cost component: improved optical amplifiers using distributed Raman amplification allow signals to traverse longer distances without amplification and/or r...
