By dynamically equalizing gain across the C-band, these advanced amplifiers can replace conventional architectures that rely on separate booster, in-line, and pre-amplifier stages simplifying network design while reducing equipment count, power consumption, and operational costs. Integrated Dynamic Gain Equalization. Single-Amplifier Architecture Across the C-Band. Reduced Equipment, Power Consumption, and OPEX. Atlas Optical Amplifier Performance: Atlas is a compact smart EDFA that integrates two high-performance optical amplifiers and a photonic-based Dual Dynamic Gain Equalizer into a single, compact module. Principe of Operation: PhotonPath Dual EDFA is based on reconfigurable Dynamic Equalizers realized in our proprie-tary integrated photonic platform with ultra-low losses. The key differentiation is the ability to compensate for several spectral profiles, thus covering a wide operational mask while keeping a low Noise Figure (NF). Atlas impact on network: Metro area network simulations show a reduction of optical amplifiers cost up to 20%, by choosing Atlas over a commercial EDFA. Further savings can be achieved by considering OEO regeneration and maintenance costs.
