Multiplexed QKD System (Toshiba)
QKD Systems by Toshiba (JP)
Overview
Toshiba's QKD system engineered to co-exist with conventional data traffic on the same optical fiber, eliminating the need for dedicated dark fiber. Uses a quantum channel in the telecom O-Band, keeping the C-Band free for customer traffic. Supports both single-fiber (bi-directional) and dual-fiber (uni-directional) operation.
