CWDM OTDR Modules 

VIAVI CWDM OTDR solution enables cable operators, dark fiber providers and telecommunication service providers to test through MUX/DEMUX and perform a complete end-to-end link characterization or troubleshooting of active C-RAN, DAS and mobile fronthaul CWDM networks.

Benefits:

• The most compact CWDM OTDR solution in the market: 18 CWDM wavelengths covered in only 2 OTDR modules.
• Perfect for end-to-end link characterization during network deployment / construction.
• Ideal to test new CWDM wavelength routes or pinpoint faults and know their exact locations without disrupting traffic on active channels.
• Can be combined with a CWDM spectrum analyzer module (COSA-4055) to measure the wavelengths and power levels of active CWDM channels.

Applications:

• Characterize end-to-end links with exact CWDM wavelengths.
• Troubleshoot active networks with in-service testing capability.
• Verify end-to-end continuity with the continuous wave source function.

Key Features:

• CWDM8U version includes 8 wavelengths from 1471nm to 1611nm.
• CWDM10U version includes 10 wavelengths from 1431nm to 1611nm.
• CWDM10L version includes 10 wavelengths from 1271nm to 1451nm.
• Integrated CW light source with modulation capability (same OTDR wavelengths).
• Eliminate OTDR interpretation errors with Smart Link Mapper (SLM) option (converts the OTDR trace into icons – splice, connector, MUX/DEMUX).
• Compatible with T-BERD/MTS-2000, -4000, -4000 V2 and -5800 platforms.
