Datasheet

Overview

The VIAVI E4136C is the tri-wavelength 1310/1550/1625 nm member of the 4100 C OTDR module family. It is a plug-in module for the T-BERD/MTS-2000, T-BERD/MTS-4000 V2, T-BERD/MTS-5800, OneAdvisor 800 and FTH-9000 platforms, and is ordered with a PC or APC test port (E4136C-PC or E4136C-APC). Module portability allows fiber test capability to move between VIAVI platforms that also cover coax and RF, active xWDM, MPO/ribbon cable or network-layer tests.

The 4100 C variant provides up to 45 dB RMS dynamic range, up to 256,000 acquisition points, a 0.1 to 400 km distance display range and pulse widths from 3 ns (with the EPULSE3NS software option) to 20 µs. All three wavelengths share a single test port, and an integrated light source is available on the OTDR port; an in-line broadband power meter is a hardware option. Permanent live-traffic detection avoids damage to transmission equipment, and a test port health check verifies launch conditions before each acquisition.

Software and workflow

Results are presented in SmartLink Mapper (SLM), trace and event-table views with direct correlation of a selected event. The SmartTEST assistant guides technicians through setup, testing, review and reporting. Optional software adds TrueBIDIR on-board bidirectional OTDR analysis and Loopback testing (FiberComplete PRO), Cable-SLM project management for high fiber count cables, and FTTH-SLM applications for PON architectures including unbalanced and tapered splitters. The module supports hollow core fiber testing, and with the ReportPRO hollow core fiber license a Hollow Core Fiber Loss Profile report can be generated. Test Process Automation (TPA) links the instrument to cloud-based job assignment and results submission.
