Products
Our QKD offering has two variants: the multiplexed system which can be operated on data carrying fiber, and the long-distance system for the highest possible key rate and range.
Lineup
Multiplexed QKD System
The Multiplexed QKD system allows operation on data carrying fiber, thereby removing the requirement for costly dark fiber. It uses a quantum channel with wavelength in the telecom O-Band, leaving the C-band free for customer traffic. It can operate in the conventional mode with a fiber pair carrying uni-direction traffic, or with a single fiber carrying bi-direction quantum and classical signals.
Key features:
- Typical key rate : 300 kb/s for 10 dB loss
- Maximum Range (ideal SM fibre): 90km+
- Fiber requirement : single or dual fibers
- Option to multiplex data in C-band
- Efficient BB84 protocol with decoy states and phase encoding
- Key failure probability of less than 10-10 equivalent to less than once in 30,000 years
- Proprietary self-differencing semiconductor detectors
Key features:
- Typical key rate : 40 kb/s for 10 dB loss
- Range of up to 70km
- Fiber requirement : single or dual fibers
- Option to multiplex data in C-band
- Efficient BB84 protocol with decoy states and phase encoding
- Key failure probability of less than 10-10 equivalent to less than once in 30,000 years
- Proprietary self-differencing semiconductor detectors
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 limited bandwidths of multiplexed data within the C-band.
Key Features:
- Typical key rate = 300 kb/s for 10dB loss
- Maximum Range (ideal SM fibre): 150km+
- Two fibers required
- Efficient BB84 protocol with decoy states and phase encoding
- Key failure probability of less than 10-10 equivalent to less than once in 30,000 years
- Proprietary self-differencing semiconductor detectors
Key Features:
- Typical key rate = 300 kb/s for 10dB loss
- Range of up to 120km
- Two fibers required
- Efficient BB84 protocol with decoy states and phase encoding
- Key failure probability of less than 10-10 equivalent to less than once in 30,000 years
- Proprietary self-differencing semiconductor detectors
