Datasheet

Overview

The VIAVI E4118FB65-APC is a 4100 B OTDR module equipped with a single filtered 1650 nm wavelength and an SC/APC test port. The filtered wavelength is dedicated to in-service troubleshooting: the module can test a fiber while live traffic is present on the transmission wavelengths, with live wavelength isolation of more than 45 dB from 1260 to 1620 nm. Permanent live traffic detection protects transmission equipment and avoids poor measurement results.

As a member of the 4100 Series, the module fits the T-BERD/MTS-2000, T-BERD/MTS-4000 V2, T-BERD/MTS-5800, OneAdvisor 800 and FTH-9000 platforms. Module portability allows fiber test capability to be moved between VIAVI platforms that also cover coax and RF, active xWDM, MPO/ribbon cable or network-layer tests such as Ethernet, BERT and CPRI.

The 4100 B optical specification provides 41 dB RMS dynamic range at 1650 nm, up to 256,000 acquisition points, a 0.65 m event dead zone and a 45 m attenuation dead zone through a PON splitter. Pulse widths range from 5 ns to 20 µs and the distance display range reaches 260 km.

Analysis and workflow software

SmartLink Mapper (SLM) analyzes the trace, identifies passive optical elements and represents them as icons in a fiber link map with pass/fail information, with direct correlation between the SmartLink, Trace and Table views. SmartTEST guides the user through setup, testing, result review and reporting in four steps. Optional mainframe software adds TrueBIDIR and Loopback bidirectional OTDR analysis (FiberComplete PRO), Cable-SLM project management for high fiber count cables and FTTH-SLM applications for PON architectures. Test Process Automation (TPA) connects the instrument to cloud-based job assignment and results submission.

An in-line broadband power meter is available as a hardware option on the OTDR port.
