VIAVI 4100-Series OTDR modules enable field technicians to rapidly, reliably, and cost-effectively install, turn up, and troubleshoot any optical network architecture – The optical performances of the 4100-Series OTDR modules combined with the complete suite of T-BERD/MTS, CellAdvisor 5G or OneAdvisor-800 platforms testing features ensure that any testing job is done right the first time.
Fiber infrastructure is the foundation of the network performance and the quality of delivered services. An OTDR is the only tool that verifies the condition of installed cables and passive components to ensure fiber links meet design specifications and contractor’s workmanship meets the required quality.
Module portability allows migration of fiber test capabilities between different VIAVI platforms, offering the flexibility to move existing fiber certification tools to different technologies such as coax and RF, active xWDM, MPO/ribbon cables or network layer tests such as Ethernet, BERT, CPRI, etc.

(4) Laser at 25°C and measured at 10µs
(5) The one-way difference between the extrapolated backscattering level at the start of the fiber and the RMS noise level, after 3 minutes averaging
(6) Measured at ±1.5 dB down from the peak of an unsaturated reflective event, using 5ns pulsewidth
(7) Measured at ±0.5 dB down from the linear regression using a FC/UPC-type reflectance, using 5ns pulsewidth
