Opis produktu VIAVI DWDM OTDR Module – 4100-Series
VIAVI T-BERD/MTS
4100-Series DWDM OTDR Module
For T-BERD®/MTS-2000, -4000 V2, -5800 Platforms
As xWDM technology adoption continues to grow in access networks for broadband services, technicians require comprehensive and lightweight xWDM test tools. Consisting of a single module, the VIAVI C-band DWDM OTDR solution enables cable, wireless, and telco operators to perform complete end-to-end link characterization and troubleshooting of DWDM and hybrid CWDM/DWDM networks.
The DWDM OTDR module’s optical performance, combined with the complete suite of T-BERD/MTS platform testing features, ensures that comprehensive testing is done right the first time.
Standard testing features include:
- Auto-setting of the acquisition parameters
- Summary results table with pass/fail analysis per the international standards
- Comprehensive event diagnosis
- FastReport onboard report generation
Key Benefits
- Characterize fiber links with exact DWDM wavelengths
- Troubleshoot live networks with in- service testing capability
- Verify end-to-end continuity through MUX/DEMUX and ROADMs using the continuous wave source function
- Smart Link Mapper (SLM) eliminates OTDR interpretation errors without impacting test times
Key Features
- Tunable DWDM OTDR module at ITU-T
G.694.1 wavelengths
- C-band - 1528 nm to 1568 nm
- 44 dB dynamic range for access and metro applications
- Integrated CW light source with modulation capability
- Instantaneous traffic detection
Applications
- Metro & access rings, business to business, advanced C-RAN fronthauls & next gen FTTH networks
- Qualification of fronthaul access networks
- Testing new DWDM wavelength routes without disrupting traffic on active channels
- Pinpointing faults and their exact locations while in service
