MIMOPT TECHNOLOGY Presents Research at SPPCOM 2025, Marseille
MIMOPT TECHNOLOGY Presenting New Research on Next-Generation Fibre Systems
MIMOPT TECHNOLOGY presented a new research paper at the Signal Processing in Photonic Communications conference (SPPCom 2025), held as part of the Optica Advanced Photonics Congress in Marseille, France in July 2025. The paper is co-authored by Jamal Darweesh, Akram Abouseif, Ghaya Rekaya-Ben Othman, Yves Jaouën, and Rami Klaimi, and will be presented by Jamal Darweesh. If you are attending, we would love to see you there — come catch the presentation and connect with the MIMOPT team in person!
What the Research Is About
As demand for data capacity continues to grow, the telecommunications industry is exploring new types of optical fibre that can carry multiple data streams through a single cable at the same time. One promising approach is coupled multi-core fibre, where several parallel channels run inside a single fibre strand and interact with each other. This interaction, known as crosstalk, is one of the main challenges in making such systems work reliably over long distances.
In this paper, the MIMOPT team proposes a smarter way to remove that crosstalk at the receiver end, using a two-stage approach. Instead of trying to process all channels together in one large, computationally demanding step — as is done in conventional systems — the proposed method splits the processing into two lighter, sequential stages. The result is a 66% reduction in computational complexity, while also reducing the risk of the system failing to process the signal correctly. This makes the solution more practical for real-world, long-distance fibre deployments without sacrificing performance.
About SPPCom
Signal Processing in Photonic Communications (SPPCom) is a premier international conference organised by Optica (formerly OSA), bringing together researchers and engineers working at the intersection of signal processing and optical communications. It is held annually as part of the Optica Advanced Photonics Congress, which covers the full breadth of photonics research from fundamental science to applied systems.
