Gaithersburg, Maryland, USA – February 04, 2025,, GL Communications Inc., a global leader in telecom testing solutions, addressed the press regarding their latest release of the PacketExpert™ 10GX, used for testing Ethernet and IP networks and individual network infrastructure.

Vijay Kulkarni, CEO of GL Communications, states, “The PacketExpert™ is a multi-functional Ethernet tester that supports both electrical and optical interfaces. It can conduct a wide range of tests, including Bit Error Rate Testing, Smart Loopback Testing, RFC 2544, ITU-T Y.1564 testing to verify service level agreements, Wide Area Network Emulation, Packet Recording and Playback, Multi-stream UDP/TCP Traffic Generation, Wirespeed Ethernet Tap, and TCP Throughput Testing (RFC 6349). It supports speeds up to 10 Gbps across electrical and single-mode and multi-mode optical interfaces. GL also offers compatible SFPs and fiber-optic cables, providing a ready-to-use testing solution.”

A single PacketExpert™ 10GX device features two 10/2.5/1 Gbps ports and two 10/100/1000 Mbps ports, all of which support both electrical and optical connections. The device is fully compatible with all SFP and SFP+ modules available on the market.

Controlled via a Windows® PC through a USB connection, the PacketExpert™ offers an intuitive Graphical User Interface (GUI) for configuring test parameters, starting and stopping tests, viewing real-time graphs and statistics, and exporting results.

For larger testing environments, rack-mount variants of the PacketExpert™ 10GX are available. These enclosures can house up to six devices, delivering a total of 24 GigE ports. Additionally, the solution includes optional licensing for Python and C# Scripting, enabling automation and repetitive testing workflows.

Other key features include:

• 10 Mbps, 100 Mbps (Base-T and Base-FX), 1G, 2.5G, 10G speeds
• Electrical and Optical (SFP and SFP+) interfaces
• Wirespeed Bit Error Rate Testing
• RFC 2544 - Throughput, latency, frame loss, and back-to-back performance tests
• Aggregated Ethernet network tap and filter. Can include 12 TTL triggers based on user defined packet detection
• ITU-T Y.1564 - Test service level agreements
• Wirespeed packet capture and playback
• Layer wise Testing - Ethernet, Stacked VLAN (Q-in-Q), Stacked MPLS, IP, UDP
• Smart loopback (auto layer detection) and layer-wise loopback testing
• TCP Throughput Testing - according to the RFC 6349 standard
• Multi stream traffic generation and analysis - send and receive multiple UDP streams and measure throughput, packet loss, delay, jitter, and packet reordering at full wirespeed
• Generate frame sizes from 64 bytes to 16000 bytes
• Emulate impairments such as congestion, latency, loss, jitter, and packet reordering
• Playback previously recorded traffic with precise time stamping to emulate real world traffic
