DESCRIPTION:

The VIAVI 4100 Series Hi-Res Multimode OTDR Module is a high-resolution multimode optical test platform engineered for characterization, troubleshooting, certification, and fault isolation of short-range multimode fibre infrastructures across enterprise, hyperscale data centre, aerospace, defence, industrial, and manufacturing environments. (viavisolutions.com)

Designed for deployment with compatible VIAVI platforms including the T-BERD/MTS-2000, T-BERD/MTS-4000 V2, T-BERD/MTS-5800, OneAdvisor 800, and SmartOTDR systems, the Hi-Res Multimode OTDR provides ultra-short event dead zones and high spatial resolution required for dense multimode fibre environments.

The platform supports testing across:

• OM1 multimode fibre
• OM2 multimode fibre
• OM3 multimode fibre
• OM4 multimode fibre
• OM5 wideband multimode fibre
• enterprise structured cabling
• hyperscale data centre infrastructures
• short-range optical interconnects
• aerospace optical systems

The Hi-Res Multimode OTDR is engineered for:

• multimode fibre troubleshooting
• fibre certification
• short-range fault isolation
• splice analysis
• connector characterization
• optical loss analysis
• data centre fibre validation
• enterprise fibre maintenance
• patch panel troubleshooting
• high-density fibre diagnostics

Its high-resolution OTDR architecture incorporates ultra-short pulse widths and very low event dead zones to enable clear visualization of closely spaced fibre events commonly found within patch panels, MPO breakout systems, cross-connect environments, and high-density enterprise cabling infrastructures.

The platform supports VIAVI Smart Link Mapper (SLM) graphical fibre topology analysis, simplifying OTDR trace interpretation and accelerating fault isolation for technicians operating within dense multimode cabling environments. 

The module architecture is optimised for:

• short-range multimode links
• data centre cross-connect systems
• enterprise backbone cabling
• SAN infrastructures
• campus fibre environments
• high-density MPO deployments
• manufacturing optical systems
