CWDM OTDR Modules – 4100-Series for T-BERD/MTS-2000, -4000 V2 and 5800 Platforms.
A CWDM OTDR test solution to deploy or maintain and troubleshoot in-service CWDM fiber networks.
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. Learn more about OTDR Testing.
4100-Series CWDM OTDR Modules; For T-BERD/MTS-2000, −4000 V2, −5800 Platforms
Connect the VIAVI 4100-Series CWDM OTDR family to successfully deploy and maintain C-RAN, DAS, CWDM, and fronthaul networks. CWDM OTDRfamily optical performance, combined with the T-BERD®/MTS platform’s suite of testing features, ensures that testing jobs are performed right—the first time.
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 |
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 |

Notes:
(1) Laser at 25°C and measured at 10 µs.
(2) The one-way difference between the extrapolated backscattering level at the start of the fiber and the RMS noise level, after 3 minutes averaging and using the largest pulsewidth.
(3) Measured at ±1.5 dB down from the peak of an unsaturated reflective event using the shortest pulsewidth.
(4) Measured at ±0.5 dB from the linear regression using a FC/PC reflectance and using the shortest pulsewidth.
(5) Subtract 3 dB when used in modulation mode (270/330/1/2 kHz).
