Placement of hybrid optical amplifier in fiber optical communication systems

Optik, 2012
Abstract In this paper, we investigated the post-, pre- and symmetrical power compensation methods for a different position of hybrid optical amplifier RAMAN–EDFA in fiber link. The effect of increase in signal input power for three power compensation methods is compared in terms of bit error rate, eye closure penalty and output received power. It is

Hybrid flat gain C-band optical amplifier with Zr-based erbium-doped fiber and semiconductor optical amplifier

Laser Physics, 2010
An efficient gain-flattened C-band optical amplifier is demonstrated using a hybrid configuration with a Zirconia-based Erbium-doped fibre (Zr-EDF) and a semiconductor optical amplifier (SOA). The amplifier utilizes a two-stage structure with a midway isolator to improve flat gain characteristic and reduce noise figure. At input signal power of −30 dBm,

Performance Analysis of Hybrid Optical Amplifier for Hybrid Passive Optical Networks

Wireless Personal Communications, 2021
Performance of RAMAN-EDFA hybrid optical amplifier (HOA) for 400 × 10 Gbps super dense hybrid optical system has investigated for multiplay services (voice, data, video, mobile service and integrated service) in terms of bit error rate (BER) and quality factor (Q-factor) in the context of fix channel spacing (100 GHz) and varying channel spacing (100 ...
