Calnex

Calnex

Calnex Solutions is a Scottish test and measurement company specializing in network timing and synchronization test equipment. Their instruments are designed to validate the performance of timing protocols such as IEEE 1588 Precision Time Protocol (PTP) and ITU-T SyncE, which are critical to modern packet-based telecommunications networks. As mobile networks evolve to 5G and packet fronthaul architectures, precise timing and phase synchronization become essential, making Calnex instruments key tools for network equipment manufacturers, operators, and standards compliance labs.

Calnex products support both lab-based protocol conformance testing and live network monitoring, enabling engineers to characterize timing impairments, measure time error, and verify equipment behavior under degraded synchronization conditions.

Key Product Lines

• Paragon ONE — precision timing protocol tester for PTP, SyncE, and GNSS-based timing validation in lab environments
• Sentinel — network timing analyzer for live in-service monitoring of synchronization performance

Industries Served

Calnex equipment is used by mobile network operators, telecommunications equipment manufacturers, data center operators, and standards bodies validating 5G, LTE, and packet transport network infrastructure. Their instruments are deployed in engineering labs and network operations environments where timing accuracy directly impacts service quality and regulatory compliance.
