Improvement on advanced security network module on real telecommunication infrastructure

We successfully implement and improved Advanced Security Network Module on real fiber optic test-bed by riding on existing laid telecommunication fiber. Transmitting through dark fiber was achieved with a maximum key rate of 2056 bit/s that unconditionally protects the establishment of shared keys between two remote distances. Mixing of Telecom standard single mode fiber type which consist of normal G652 and low water peak fiber G652D, Fresnel reflection and the effect of train passing by on some portion of the entire 44.5km length are among the obstacles while deploying the security network module equipment.
