May                       1, 2017 — Viavi today introduced the 4100-series                       DWDM OTDR for its T-BERD/MTS-2000,                       4000, and 5800 platforms. As DWDM technology continues                       to penetrate into access networks, technicians require comprehensive,                       cost-optimized DWDM test tools. With these, techs can deliver                       reliable deployments during construction and support efficient                       troubleshooting of faulty links for ongoing maintenance.

Consisting                       of a single module, Viavi's C-band OTDR enables wireless,                       cable, and telco operators to perform complete end-to-end                       link characterization and troubleshooting through the optical                       Mux/Demux for newly deployed or active DWDM and hybrid CWDM/DWDM                       networks.

Benefits:.                      

• Test                           new DWDM wavelength routes and pinpoint exact fault                           locations without disrupting traffic on active                            
                           channels
  
  

• Verify                           end-to-end continuity through ROADM network                           elements with the integrated C-band tunable laser source                           mode
  
  

• Easy                           setup and interpretation of results with SmartConfigs                           and Smart                           Link Mapper (SLM) OTDR applications
  
  

• Comprehensive                           qualification and troubleshooting solution,                           for hybrid CWDM/DWDM networks when combined with Viavi's                            CWDM                           OTDR modules
  
  

• Portable                           and lightweight, most compact DWDM OTDR solution                           available for physical layer fiber certification and                           troubleshooting

DWDM                       technology has been well adopted in long-haul transmissions                       for decades. With the growing need for bandwidth driven                       by data-hungry applications and business services, DWDM                       technology has now found its way into access networks. CATV                       operators delivering DWDM-enabled business services and                       wireless operators moving to DWDM for CRAN front hauls,                       require a simple way to validate routes to connect new customers                       and to troubleshoot faulty links in a timely manner without                       disrupting existing services.

Viavi                       is the worldwide leader in OTDR manufacturing and has been                       awarded the coveted Frost & Sullivan Fiber                       Optics Test Equipment Market Leader Award for fiber-optic                       test equipment six years in a row.
