Physical fibre threat detection for network operators

Communications operators need to locate physical interference around their optical-cable routes. Prisma Photonics turns existing fibre into a distributed sensor through the PrismaCyber solution. Classified acoustic events and associated positions reach the command centre, giving network operations staff a view of represented digging, access-point openings or cable tampering.

An optical interrogator, the unit that sends and measures sensing light, connects to a suitable single-mode dark fibre. Reflections from its light pulses provide changing signatures along the selected cable. Machine-learning and mathematical analysis classify chosen patterns and associate them with the represented route. The monitored fibre supplies the sensing path, while compatible central-system integration transfers selected information and alarms to the operator's existing tools.

Staff examine events around handholes, manholes, cabinets or nearby excavation before planning a response. Selected analysis also follows optical-fibre tapping and other physical tampering signals. The shared command view concentrates those classified events and their locations across the represented network. Operators compare the warning with planned work, inspect the affected infrastructure and arrange the appropriate field action. The resulting route context helps the team focus its investigation on the reported physical condition.
