DESCRIPTION:

The VIAVI T-BERD/MTS-4000 V2 is a modular dual-bay optical network test platform engineered for installation, activation, maintenance, troubleshooting, and certification of fibre optic communication infrastructures across telecom, enterprise, wireless, FTTH, metro, core, and data centre environments.

Designed for fibre technicians, transport engineers, contractors, and service providers, the MTS-4000 V2 combines OTDR analysis, fibre characterization, optical spectrum analysis, connector inspection, Ethernet troubleshooting, and CWDM/DWDM validation within a compact ruggedised handheld architecture optimised for field deployment.

The platform supports testing across:

• FTTH and FTTx networks
• Metro and core optical transport
• CWDM and DWDM infrastructures
• Enterprise fibre systems
• Wireless and 5G fronthaul/backhaul
• Data centre fibre environments
• HFC and access networks
• Passive Optical Networks (PON)

The MTS-4000 V2 is engineered for:

• OTDR fibre troubleshooting
• fibre certification
• optical loss analysis
• CWDM/DWDM validation
• fibre characterization
• connector inspection
• optical spectrum analysis
• PON testing
• Ethernet/IP troubleshooting
• network maintenance operations

Its dual-bay modular architecture allows simultaneous operation of multiple fibre test technologies including OTDR, Optical Spectrum Analyzer (OSA), FibreComplete bi-directional IL/ORL testing, MPO testing, CWDM/DWDM OTDR modules, and Ethernet/IP service modules from a single field platform.

The platform integrates VIAVI Smart Link Mapper (SLM) technology for icon-based OTDR trace interpretation, simplifying fibre event analysis and accelerating fault isolation for FTTH, enterprise, wireless FTTA, and metro transport deployments.

Advanced workflow automation and cloud integration through StrataSync and Smart Access Anywhere (SAA) enable remote technician assistance, centralized asset management, automated reporting, and workflow-driven field diagnostics.

The MTS-4000 V2 supports interoperability with VIAVI 2000-, 4000-, and 5800-series optical modules, providing scalable upgradeability across evolving optical network environments.
