Telecommunications consortiums completed a successful 120-kilometer field test of Quantum Key Distribution over active dark fiber networks. The deployment proved that quantum-secured channels can operate alongside high-capacity commercial data streams without signal degradation or unacceptable key generation dropoffs.
Integration with Existing Infrastructure
By leveraging standard multiplexing techniques, operators integrated quantum hardware directly into existing suburban exchange hubs. The test validates the commercial feasibility of securing financial transaction backbones against future decryption threats.
