Viavi E41CWDM10L OTDR Module

Overview

The Viavi E41CWDM10L is a 10-wavelength CWDM OTDR module designed for deploying and maintaining in-service CWDM fiber networks. It enables cable operators, dark fiber providers, and telecommunications service providers to test through MUX/DEMUX equipment and perform end-to-end link characterization or troubleshooting of active C-RAN, DAS, and mobile fronthaul CWDM networks.

Key Features

• 10 wavelengths from 1271nm to 1451nm (±3nm tolerance)
• Integrated continuous wave (CW) light source with modulation capability
• Smart Link Mapper (SLM) option to convert OTDR traces into diagnostic icons for splices, connectors, and MUX/DEMUX elements
• Compatible with T-BERD/MTS-2000, -4000, -4000 V2, and -5800 platforms
• 35 dB dynamic range with 1.5m event dead zone and 5m attenuation dead zone
• Automatic traffic detection for non-disruptive in-service testing

Applications

• Characterize end-to-end links with exact CWDM wavelengths during network deployment
• Troubleshoot active CWDM networks without disrupting in-service channels
• Verify end-to-end continuity with integrated continuous wave source
• Support C-RAN, DAS, and mobile fronthaul network testing

Benefits

• Compact solution covering 18 CWDM wavelengths with only 2 modules
• Complete fiber link characterization during deployment and construction phases
• Precise fault location without disrupting active traffic
• Optional integration with CWDM spectrum analyzer (COSA-4055) for enhanced wavelength and power analysis
