T-BERD/MTS-5800 Handheld Network Tester

All-in-one handheld network and fiber testing

This tester is the industry’s smallest 10G handheld instrument and supports testing throughout the entire service life cycle including fiber characterization, service activation, troubleshooting, and maintenance.

T-BERD/MTS-5800 Handheld Network Tester

The T-BERD/MTS-5800 handheld network tester is the one tool that network technicians and engineers need to install, turn-up, and maintain their networks. It supports both the legacy and emerging technologies required to handle various network applications including metro/core, mobile backhaul, and business services installations. The industry’s smallest handheld instrument can test throughout the service life cycle, including fiber characterization, service activation, troubleshooting, and maintenance. Advanced Ethernet test features such as TrueSpeed per RFC 6349, J-Profiler™, Wirespeed capture/decode, and automated J-Mentor, help field technicians test their networks faster and more accurately than ever before.
