AAHAN (INC) PTE LTD is a Singapore-founded company focused on fiber optics, telecommunications, education, and security solutions. It combines product development with consulting and training to help organizations improve their technical expertise, operational efficiency, and safety.

Its security offering, the Fiber Optic Perimeter Intrusion Detection System (FO-PIDS), uses optical fiber as a distributed, passive sensing component to detect perimeter intrusions. The system supports hardwired, scalable zones, allowing customers to expand coverage while maintaining monitoring across functioning zones if one becomes defective. It is designed for critical infrastructure and sites including airports, industrial facilities, power plants, pipelines, prisons, and research facilities.

For education and experimentation, AAHAN offers the Light Runner, a modular fiber-optic laboratory with more than 40 experiments in optics, optoelectronics, and optical communications. It includes industry-grade components and software for monitoring, control, instruction, and saving results. The company also provides a Quantum Key Distribution Kit for exploring the BB84, SARG04, and B92 protocols. AAHAN’s consulting and training services address challenges such as inefficient monitoring, skills gaps, and outdated knowledge.
