Datasheet

Overview

The VIAVI E4146A-PC is the PC-connector version of the 4100 Series Quad OTDR module. It combines multimode (850/1300 nm) and singlemode (1310/1550 nm) OTDR test ports in one module for users who work with both fiber types, such as installers and contractors, wireless service providers, and enterprise technicians. It is intended for installing, turning up, and maintaining premises and enterprise, access, metro, and wireless fronthaul/backhaul networks.

The module provides up to 26 dB of dynamic range in multimode and up to 37 dB in singlemode, with short event and attenuation dead zones and up to 256,000 acquisition points. An integrated continuous wave light source is accessible through both OTDR ports, so fiber identification and continuity tests can be performed without switching ports. Pass/fail thresholds follow TIA/IEC standards, propagation delay can be measured in multimode per TIA-568-C, and the module certifies Tier 2 premises networks. IEC 61280-4-3 compliant measurements are possible with an external modal controller.

Platforms and software

The module plugs into the T-BERD/MTS-2000, T-BERD/MTS-4000 V2, T-BERD/MTS-5800 and OneAdvisor 800 platforms, and its optical performance is combined with the platform's test and reporting features. Standard features include automatic macrobend detection, a summary results table with pass/fail analysis, the icon-based SmartLink Mapper results view, and FastReport on-board report generation. The module ships with an SC/PC test port adapter for the singlemode port and an SC/PC test port adapter for the multimode port; FC, SC, LC and ST adapters are available.
