Dry plant technologies and network management

The lines between subsea and terrestrial technologies have blurred, allowing convergence in the solutions resulting in Submarine Line Terminal Equipment (SLTE), that offers lower space and power requirements than in the past. The rapid development of Data Centers (DC) has changed the terminating points from the Cable Landing Stations (CLS) to DCs, further blurring the lines between subsea and terrestrial networks. This has resulted in the entire photonic network between the cable landing station and the modems to be part of the SLTE architecture. The rapid scale of deployment has further accelerated the need to leverage Artificial Intelligence to turn-up and operate these networks. In this Topic Area, authors are encouraged to explore advances and trends in dry-path technologies and the network operations that power them from hardware and software perspectives.


“We embrace the opportunity we have been given to organize the SubOptic 2025 Topic Area “Dry Plant technologies and Network Management”. This topic area has hosted numerous influential papers in past conferences, and we expect this trend will continue in 2025. We look forward to authors providing insights how submarine network operators can expect the network to change based on how recent advances in modem development and intelligent software are addressing the drive to improve the spectral efficiency of networks while simplifying the operation of these engineering marvels.”

Subjects that can be addressed include, but are not limited to:

  • The role of Artificial Intelligence, machine learning and trend analysis in the automation of submarine network operations and management or the prediction of systems failures.
  • Advances of next generation Digital Signal Processing in transponder technologies and the impact of coherent pluggable technology on submarine networks.
  • SLTE architecture advances for open cable systems
  • Solutions for connections and protection configurations between the Cable Landing Station and the POP/DC.
  • The impact of emerging terrestrial technologies on Wetplant designs
  • The development and operation of Open Cable Interface (OCI) solutions, including innovation in Wetplant monitoring (LME, telemetry, COTDR, etc.).
  • Management and operation of Spectrum “partitioning” solutions (managed spectrum, shared spectrum)
  • Reliability
  • PFE development for emerging Wetplant designs
