Quantum Link Assurance System

QLAS is an easily deployable system that provides highly accurate, real-time detection of sophisticated tamper attacks on optical fibre.

What it is

Physical-layer monitoring  for high-value fibre links

It runs alongside existing data channels with standard data encryption, post quantum or even QKD. It integrates seamlessly with SDN/NOC workflows and is proven on metro and long-haul links—even with amplifiers.

Physical-layer monitor

Senses subtle tamper/eavesdropping activity using quantum-inspired signal analysis.

Deployable now

Proven on field deployed fibre alongside standard network traffic and QKD networks.

Network-friendly

Uses a single DWDM channel or OSC and coexists with live traffic and amplifiers.

Benefits

What makes QLAS unique?

Discuss evaluation access

Catch sophisticated attacks early

Fuses multiple metrics to reduce false alarms and raise precise alerts in real time.

Locate issues fast

Supports anomaly localisation and OTDR-based fault triage to speed recovery.

Fits existing networks

Simple fibre input/output; no impact on data bandwidth; works on long-haul with amplifiers.

Operationally friendly

SDN approach with simple dashboards, and containerised API compatible with standard Network Operating Centre.

Complements post-quantum encryption & QKD

Adds real-time breach and tamper visibility; defence-in-depth.

Long distance operation

Proven with multiple optical amplifiers over hundreds of kilometres.
