Fibre qkd
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.

Key Rate (Typical)
40 kb/s @ 10 dB loss
Range (ideal SM fibre)
Up to 70 km
Fibre requirement
One or two fibres
Multiplexing Compatibility
Option to multiplex customer data in C-band
Key Exchange Protocol
Efficient BB84 protocol with decoy states and phase encoding
Security Parameter
Key failure probability < 10 -10
Detection Technology
Proprietary self-differencing semiconductor detectors
Dimensions
Standard 19″ rack mount, height = 3U

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.

Key Rate (Typical)
300 kb/s @ 10 dB loss
Range (ideal SM fibre)
Up to 120 km
Fibre requirement
Two Fibres
Multiplexing Compatibility
Key Exchange Protocol
Efficient BB84 protocol with decoy states and phase encoding
Security Parameter
Key failure probability < 10 -10
Detection Technology
Proprietary self-differencing semiconductor detectors
Dimensions
Standard 19″ rack mount, height = 3U
