Abstract

In this experiment, a commercial Quantum-Key-Distribution (QKD) system from Toshiba was integrated into a carrier-grade Fiber to the Home (FTTH) optical access network. The setup replicated real-life FTTH deployments with a 1:16 user GPON configuration. The QKD transmission occurred over a total of 4km consisting of two spitting stages. By optimizing transmission powers, a QKD link with 17 kbps Secure Key Rate (SKR) and 4.63% Quantum Bit Error Rate (QBER) was achieved, while maintaining 9 operational ONTs providing high-speed internet services. This successful demonstration showcases the feasibility of QKD over a GPON, enhancing access network security.
