Ali ImranGAITHERSBURG, Md., May 20, 2026 (ZEEST MEDIA) GL Communications Inc., a global provider of network testing solutions, announced enhanced Bit Error Rate Testing (BERT) capabilities within its PacketExpert™ Ethernet testing platforms through the addition of Timestamped Periodic Logging, enabling engineers to automatically capture timestamped error statistics during long-duration Ethernet stability and interoperability testing.
PacketExpert™ is GL’s comprehensive Ethernet testing platform designed for validation of isolated devices and end-to-end network paths across copper and fiber optic interfaces ranging from 10/100/1000 Mbps up to 10 Gbps. The platform supports both manual operation through an intuitive graphical user interface and Python scripting for automated testing environments.
Many network equipment manufacturers and service providers perform Ethernet validation under harsh environmental and operational conditions such as electromagnetic interference, thermal fluctuations, long-duration stress testing, and infrastructure qualification. Identifying exactly when intermittent bit errors or synchronization impairments occur during these tests is critical for effective troubleshooting and deployment validation.

GL’s enhanced Timestamped Periodic Logging capability within the Bit Error Rate Testing application addresses these requirements by automatically recording bit error statistics during active test execution without interrupting traffic generation. Engineers can configure periodic interval-based logging or selectively capture events only when errors occur, providing precise visibility into transient transmission impairments that may otherwise remain hidden in aggregated end-of-test summaries.
Vikram Kulkarni, Sales Director of GL Communications, stated: “Long-duration Ethernet stability testing often requires precise visibility into when intermittent impairments occur. PacketExpert™ with Timestamped Periodic Logging enables engineers to correlate bit errors and synchronization loss events with environmental or operational conditions, significantly improving troubleshooting efficiency and confidence in deployment readiness.”
The enhanced logging capability supports automated timestamped recording of bit error statistics, configurable logging modes, consolidated multi-port logging, and CSV export for offline analysis and reporting. Engineers can monitor historical link performance behavior over extended testing periods while simplifying root-cause analysis across Ethernet transport and backbone validation environments.

The capability is supported within the “All Port BERT” application on both the PacketExpert™ 10GX Ethernet/IP Tester supporting 10 Gbps, 2.5 Gbps, and 1 Gbps Ethernet interfaces, and the PacketExpert™ 1G Ethernet Tester supporting 10/100/1000 Mbps Ethernet interfaces.
Both platforms support wire-speed BERT validation across multiple protocol layers including Ethernet, stacked VLAN, stacked MPLS, IP, and UDP, enabling engineers to validate network reliability across Layer 2 through Layer 4 environments.
By automating structured error data collection during active testing, PacketExpert™ simplifies troubleshooting workflows and helps engineers:
- Pinpoint intermittent bit errors and synchronization loss events with precise timestamps
- Correlate impairments with environmental conditions or external network events
- Accelerate root-cause analysis during long-duration stability testing
- Validate switch, router, and transport network interoperability
- Generate repeatable exported evidence for deployment qualification and reporting
