• Nokia partnered with Orange France to complete a live network tomography trial on Orange’s optical transport network.
• Trial delivered near real-time visibility across optical links using coherent transmission data processed with Nokia Bell Labs algorithms.
• Results supported earlier detection of degradation or configuration issues, improving network validation and helping protect customer SLAs.
• Work also indicated potential capacity gains via better link condition awareness, supporting AI-assisted operations and closed-loop automation.
• Approach relied on existing installed equipment, reducing the need for field interventions.
