Welcome to OpenLightComm

OLC participated in a number of UK and EU funded projects

• AirQKD (Innovate-UK) – Development of the Quantum Key Management Layer of the project and the integration –via an SDN control/management plane- of the quantum and classical networks
• H2020 Metro-Haul (EU) - Contributed on various topics of Telco network design and modelling, development of SDN control plane and the physical layer of optical networks.

Our main expertise is in the following fields

• Open, Converged IT and Telecommunications Networks and Services
  • Softwarised Fixed-Mobile Converged Platforms based on Open Software
  • Architectural solutions for ICT
  • Multi-layer and Cross-layer Networking in Fixed Networks
• Optical Communication Systems and their Technology
  • Physical Layer Modelling and Design of Optical Communications Systems
  • Assessment of Optical Technology and its Impact on System Performance
• Quantum Key Distribution (QKD) Technologies
  • Design and development of QKD systems including: a) Key management layer (key management node and links/ KMM system); b) QKD control layer (SD-QKD Node, QKD control agents, SDN Controllers of QKD network); c) QKD orchestration layer; d) service layer.
  • Expertise on the development of QKD systems based on the ITU-T and ETSI GS QKD standards [ITU-T Y.3800, ETSI GS QKD 004, ETSI GS QKD 014, ETSI GS QKD 015, ETSI GS QKD 018]
