01 Building Singapore's Quantum-Safe Network
SpeQtral is leading the implementation of an island-wide national quantum-safe network, launched and supported by the Singapore government. With SpeQtral’s satellite-QKD capabilities, Singapore’s quantum-safe network can be extended globally.

Multiplexed QKD System
The Multiplexed QKD system allows operation on fibre which is already carrying data, thereby removing the requirement for costly dark fibre. It uses a quantum channel with a wavelength in the telecom O-Band, leaving the C-band free for customer traffic. It can operate in the conventional mode with a fibre pair carrying uni-direction traffic, or with a single fibre carrying bi-direction quantum and classical signals.

Long Distance QKD System
The Long Distance QKD System operates with a quantum channel in the telecom C-band for the longest possible range and highest possible secure key rate. It can tolerate a limited bandwidth of multiplexed data within the C-band.
