GAO Tek’s products of Ethernet are organized as follows:

Ethernet Analyzers 

Ethernet analyzers are advanced tools used to capture, decode, and examine Ethernet traffic in real time. These instruments provide granular visibility into packet flows, error rates, and protocol behavior, enabling engineers to troubleshoot latency issues, identify network anomalies, and validate traffic patterns. GAO Tek offers Ethernet analyzers that support a wide array of standards, from legacy 10Base-T to 10G Ethernet, and are compatible with both copper and fiber interfaces. 

These analyzers are widely applied in research labs, telecom environments, and enterprise IT departments for continuous monitoring and forensic-level diagnostics. Field technicians and system integrators depend on them for pre-deployment checks and in-service network optimization. 

Also known as packet sniffers, protocol analyzers, or Ethernet monitors, GAO Tek’s analyzers feature powerful filtering, reporting, and visualization tools. They are backed by our remote and onsite expert support to ensure smooth deployment even in multi-vendor networks.

Ethernet Testers 

Ethernet testers are essential devices used for verifying cable integrity, identifying wiring faults, measuring performance metrics like bit error rate, and ensuring compliance with Ethernet specifications. GAO Tek’s portfolio includes handheld testers, multifunction network verifiers, and high-performance BERTs, suitable for both entry-level checks and advanced diagnostics. 

Ideal for LAN installers, data center technicians, and field engineers, these testers validate physical layer connections as well as logical configuration issues. They help maintain uptime, reduce troubleshooting cycles, and confirm that network installations meet service-level expectations. 

Commonly referred to as cable testers, Ethernet verifiers, or network testers, GAO Tek’s solutions are engineered for rugged field use and are available in both wired and wireless variants. Each model is shipped with detailed manuals and access to GAO Tek’s technical support specialists.

Ethernet Media Converters 

Ethernet media converters enable seamless conversion between copper and fiber Ethernet networks. These devices play a critical role in extending transmission distances, improving EMI resistance, and connecting disparate network zones. GAO Tek’s media converters support both single-mode and multimode fiber, auto-negotiation, and speeds ranging from 10 Mbps to 10 Gbps. 

They’re used extensively in security infrastructure, smart campuses, manufacturing plants, and telco access layers, where long-range, interference-free connectivity is essential. With options for DIN rail mounting, PoE passthrough, and managed interfaces, our converters support advanced network control. 

Known in the industry as fiber media converters, copper-to-fiber converters, or Ethernet transceivers, our units deliver plug-and-play functionality, supported by GAO Tek’s proven quality assurance processes and expert deployment guidance.

Video Mux & Converters 

Video multiplexers and converters over Ethernet allow real-time transport, switching, and format translation of video content across IP networks. They support encoding and decoding of various video standards, HDMI, VGA, SDI, and composite, enabling seamless integration of legacy video equipment with modern Ethernet infrastructure. GAO Tek’s video mux solutions ensure high-resolution streaming, minimal latency, and strong interoperability. 

These devices are essential in security operations centers, smart traffic systems, live event production, and industrial automation environments, where multiple video feeds must be routed, recorded, and viewed simultaneously. Our mux/converter offerings also support integration with NVRs, network switches, and cloud video management platforms. 

Also known as IP video encoders, Ethernet video muxers, or video-over-IP converters, GAO Tek’s products are designed for rugged reliability and ease of use. Our decades-long collaboration with high-end users ensures each deployment is optimized for performance, scale, and uptime.
