LANBERT Media Qualification App
LANBERT Media Qualification App
Your copper and fiber cable plant serves as the foundation of your network. But do you know whether it is of sufficient quality to provide the bandwidth required? With the insatiable growth in bandwidth demands, increasing speeds of Wi-Fi APs (with Multi-Gig 2.5/5Gbps backhauls), 1Gbps to 10Gbps upgrades, and new fiber deployments, network professionals must have confidence that their network will transport all data error-free and at the maximum speed possible. Downtime, packet loss or intermittent drops are simply not an option.
Traditional cable Certification and Qualification tools validate installation quality and standards compliance. However, they don’t account for real, active equipment behavior. LANBERT goes further by transmitting actual Ethernet frames across physical media and any switch interconnects between two points. It stresses the cable with data packets to see if frames are dropped, while taking into consideration the impact of the “Digital Signal Processing” (DSP) of the active components rather than just standards compliance, meaning, it provides a real-world view of the capabilities of your infrastructure.
Pro Tip:
Don't ignore the "Noise" heatmap. Everyone obsesses over signal strength, but noise is the silent killer of Wi-Fi performance. You can have a screaming loud signal (-40 dBm), but if your noise floor is also high due to non-Wi-Fi interference (like Bluetooth, microwaves, or security cameras), your SNR will tank, and your users will suffer. Always validate SNR alongside Signal Strength.
This is why you can sometimes run 100 Mbps and PoE over a 250-meter cable. A Certification tool would fail the test immediately because it exceeds the 100-meter standard, but LANBERT exposes its real operating condition by validating what the link can truly carry, not just what the standard allows.
Available on the EtherScope® nXG, LinkRunner® 10G, and CyberScope®, LANBERT generates and measures the transmission of line rate Ethernet frames over your network cabling infrastructure, qualifying its ability to support 1G/10G on fiber and 100M/1G/2.5G/5G/10G on copper links.
Why “The Link Light is On” Isn’t Enough
Relying on a link light or a simple wire mapper is a gamble. Poor quality components and/or installation workmanship on copper cabling can result in links that are susceptible to noise, whether induced from within cable bundles or from outside events such as electrostatic discharges (ESD), crosstalk, or electromagnetic (EMF) pulses caused by motors or other machinery.
Improper connections can cause intermittent conductivity issues, particularly if any motion or vibration is present. This can cause not only bit errors and frame loss but may prevent certain technologies (multi-gig) from linking at the designated speed causing a downshift to a lower rate.
Running the LANBERT test over a long duration (up to 24 hours) serves as a “soak test” to identify the presence of intermittent issues and noise events that can corrupt network traffic. With easy-to-read trend graphs and the ability to drill down to 1-second granularity, LANBERT helps you identify exactly when errors occur.
