Ethernet Testers

GAO’s ethernet testers are devices used to test and troubleshoot ethernet network connections. These testers help verify the integrity and performance of ethernet cables, connectors, and network devices such as switches, routers, and network interface cards (NICs). Our ethernet testers are used by network technicians, IT professionals, and system administrators to ensure the proper functioning of ethernet networks.

GAO’s ethernet testers are composed of a handheld tester unit, LCD screen or display, control buttons or touchscreen interface, ethernet ports or connectors, power source, and cable connectors.

GAO Tek’s ethernet testers have the following functions:

Cable testing: Our ethernet testers perform continuity tests to ensure all wires within ethernet cables are properly connected, detect wiring faults such as open circuits or crossed wires, and accurately measure cable length for efficient troubleshooting and cable management.
Link testing: GAO’s ethernet testers assess network connectivity by measuring response time (round-trip time) to identify delays, detect packet loss to troubleshoot network congestion or quality issues, and measure throughput to determine the actual data transfer rate, helping identify performance bottlenecks.
Performance testing: Our ethernet testers evaluate network performance by measuring metrics such as bandwidth to ensure it meets desired requirements, measuring the latency to detect delays in data transmission, and measuring jitter to identify variations in latency that may affect real-time applications or voice/video communications.
PoE testing: GAO Tek’s ethernet testers validate power over ethernet (PoE) functionality by detecting power delivery to PoE-enabled devices, ensuring they receive power, and measuring power levels to verify compliance with specified ranges, assisting in troubleshooting power-related issues and ensuring reliable power supply in network deployments.
VLAN testing: Our ethernet testers verify VLAN configurations by checking VLAN tagging to ensure correct addition and recognition of VLAN tags by network devices, validate VLAN membership to ensure devices are assigned to the appropriate VLANs, and verify VLAN trunking to ensure proper transportation of VLAN traffic between switches, enabling proper VLAN segmentation, isolation, and communication within the network.

GAO Tek’s ethernet testers are rugged, versatile and precision measurement instruments. They comply with applicable industry standards such as TIA/EIA, ISO/IEC, IEEE, ANSI/TIA-568-C, EN, RoHS, FCC, and CE.

Our ethernet testers help our customers comply with relevant U.S. government regulations such as:

FCC Part 15 (Radio Frequency Devices)
RoHS (Restriction of Hazardous Substances)
NEBS (Network Equipment Building System) standards
EPEAT (Electronic Product Environmental Assessment Tool)

GAO Tek’s ethernet testers help our clients in complying with relevant Canadian government regulations such as:

ISED (Innovation, Science and Economic Development Canada) regulations
ICES (Interference-Causing Equipment Standard)
Energy Efficiency Regulations (applicable to power consumption)

Our ethernet testers have the following applications:

Network installation and verification: GAO’s ethernet testers are used during the initial setup and installation of network infrastructure to verify cable connectivity, test link connections, and ensure proper configuration.
Cable and connectivity testing: Our ethernet testers are used for testing and certifying Ethernet cables, ensuring they meet industry standards and are free from faults or wiring errors. These testers verify cable continuity, detect wiring faults, measure cable length, and identify issues such as open circuits, short circuits, or crossed wires.
Network troubleshooting and diagnostics: GAO Tek’s ethernet testers are valuable tools for troubleshooting network connectivity problems. These devices help identify faulty cables, diagnose link failures, detect network latency issues, and locate network performance bottlenecks.
Performance measurement and optimization: Our ethernet testers enable the measurement of key performance metrics such as bandwidth, latency, and throughput. By evaluating network performance, these testers help identify areas for improvement, optimize network configurations, and ensure efficient data transfer.
Power over Ethernet (PoE) testing: GAO’s ethernet testers assist in testing and verifying power over ethernet (PoE) functionality. These devices can detect and measure power levels delivered to PoE-enabled devices, ensuring proper power supply and troubleshooting power-related issues.
