tailieunhanh - Influence of ase noise on performance of dwdm networks using low-power pumped raman amplifiers

We found that the pumping configurations, ASE noise, and dispersion play an important role for improving network performance by decrease of noise figure and bit error rate (BER) of the system. Simulation results show that the lowest bit error rate and low noise figure were obtained, when using forward pumping configuration. Moreover, we have also compared ASE noise powers of the simulation with these of the experiment. These results conclude that DRA with low pump power (< 1 W) is the promising key technology for short– and/or middle-distance DWDM transmission networks. | Volume 25, Number 2 June 2015 Contents Page Hoang Ngoc Long – Challenges in Particle Physics and 3-3-1 Models Truong Trong Thuc, Le Tho Hue, Dinh Phan Khoi, and Nguyen Thanh Phong – One Loop Corrections to Decay τ → µγ in Economical 3-3-1 Model Nguyen Quoc Khanh and Mai Thanh Huyen – Transport Properties of a Quasi-two-dimensional Electron Gas in InP/In1−x Gax As/InP Quantum Wells: Correlation and Magnetic Field Effects Vuong Son, Nguyen Duc Chien, Truong Thanh Toan, Doan Tuan Anh, Mai Anh Tuan, Luong Thi Thu Thuy, Pham Thi Kim Thanh – Development of Spray Pyrolysis System for Deposition of Nano-structure Materials Tran Thi Thao, Vu Thi Hai, Nguyen Nang Dinh, and Le Dinh Trong – Optical Property and Photoelectrical Performance of a Low-bandgap Conducting Polymer Incorporated with Quantum Dots Used for Organic Solar Cells Bui Trung Ninh, Nguyen Quoc Tuan, Ta Viet Hung, Nguyen The Anh, and Pham Van Hoi – Influence of ASE Noise on Performance of DWDM Networks Using Low-power Pumped Raman Amplifiers Ho Quang Quy, Nguyen Van Thinh, and Chu Van Lanh – Ultrasonic-controlled Micro-lens Arrays in Germanium for Optical Tweezers to Sieve the Micro-particles Nguyen Tuan Khai, Le Dinh Cuong, Do Xuan Anh, Duong Duc Thang, Trinh Van Giap, Nguyen Thi Thu Ha, Vuong Thu Bac, and Nguyen Hao Quang – Assessment of Radioactive Gaseous Effluent Released from Nuclear Power Plant Ninh Thuan 1 under Scenario of Ines-level 5 Nuclear Accident Nguyen Hoang Phuong Uyen, Gajovic-Eichelmann Nenad, Frank.
