VIAVI Solutions, Inc. TBERD5800V2 Network Tester

The Viavi T-BERD 5800 V2 Network Tester is a portable, field-ready test platform designed for rigorous network testing and service verification across telecommunications and data networks. Manufactured by Viavi (formerly JDSU) and identified by MPN T-BERD 5800 V2, this instrument validates Ethernet, OTN, transport, and synchronization services with LAN and WAN interfaces for field test, network deployment, and maintenance environments. It supports Ethernet rates of 10G and 100G, OTN, OC-192, and GNSS/GPS timing to deliver end-to-end assessments of performance and timing critical for carrier Ethernet, optical transport, and service activation. Its primary function is network testing and service verification, enabling diagnostics, troubleshooting, and preventive maintenance across complex infrastructures. Common applications include testing and validation in telecommunications infrastructure, data centers, metro networks, and enterprise networks where Ethernet performance testing, optical transport validation, network commissioning, and synchronization verification are required.
