QuantLR LoQomo1
QuantLR’s LoQomo1 is a standalone, 1U Quantum Key Distribution (QKD) system, designed to work over the existing optical fiber infrastructure, and supply symmetric encryption keys to connected devices for Quantum-Safe communication.
The system includes an integrated Key Management System (KMS) enabling the deployment of ring, star, and mesh QKD networks with trusted nodes.
- Runs on dark fiber or MUX. Uses the existing fiber infrastructure and does not require an additional dedicated fiber network
- Every Alice can connect to any Bob (not factory matched), for added cost-effectiveness, simple stock management and maintenance
- Supports an Alice+Bob configuration within the same 1U enclosure (for trusted nodes, redundancy and stock management)
- Key Management System (KMS) within the 1U unit
- Simple installation – no special skills or equipment required
- Operates automatically on “power-on” (after initial configuration)
- Automatic recovery from multiple states (e.g. fiber replacement)
- Sync – pluggable SFP+, any optical channel
- Remote monitor and control
- Integrated and tested with ETSI 14 compatible devices and Cisco SKIP

Overview and technical specifications
LoQomo1 is designed to operate alongside the optical network, by multiplexing the QKD optical channels onto the same fiber used by the client or using a dedicated dark fiber for quantum communication.
The Loqomo1-MUX multiplexed system uses the O-band while the LoQomo1-DF dedicated dark fiber system uses the C-band.
LoQomo1 can be ordered as a quantum transmitter qTx, a quantum receiver qRx, and has a unique option, qTRx, hosting both the quantum transmitter qTx and quantum receiver units qRx within the same 1U enclosure. This is ideal for use within a trusted node.
