Multi-Band Programmable Gain Raman Amplifier

Uiara Celine de Moura et al.

Summary: This paper experimentally demonstrates a multi-band (S+C+L) programmable gain optical amplifier using only Raman effects and machine learning. The amplifier achieves >1000 programmable gain profiles within an ultra-wide bandwidth range of 17.6 THz (140.7 nm) in an ultra-fast way.

Cognitive and autonomous QoT-driven optical line controller

Giacomo Borraccini et al.

Summary: This study proposes and experimentally tests a vendor-agnostic optical line controller architecture capable of autonomously setting the working point of optical amplifiers to maximize the capacity of a ROADM-to-ROADM link. The controller automatically characterizes the line and utilizes an optimization algorithm to determine the working point of each amplifier, achieving high-quality transmission performance in laboratory experiments.

Autonomous Raman amplifiers in multi-band software-defined optical transport networks

Giacomo Borraccini et al.

Summary: A controller architecture for managing multi-band Raman amplification within software-defined optical transport networks is presented. The system is capable of autonomously handling Raman amplification on a single fiber span, achieving the working point requested by the control plane. Experimental validation confirms the effectiveness of the controller architecture design and the high accuracy achieved in terms of performance.

Autonomous Raman Amplifiers Using Standard Integrated Network Equipment

Giacomo Borraccini et al.

Summary: The practical needs of infrastructure management are prompting optical network operators to consider implementing Raman amplification for improved performance, which requires greater control and monitoring compared to standard EDFA management. This study proposes an embedded controller architecture and probing procedure to efficiently manage Raman amplification in disaggregated optical networks without the need for additional optical channel monitors.
