Datasheet

Overview

The VIAVI E4136B is the 4100 B performance class member of the 4100 Series OTDR modules, fitted with 1310, 1550 and 1625 nm wavelengths on a single test port. It is ordered as E4136B-PC or E4136B-APC depending on the test port polish and is delivered with an SC/PC or SC/APC test port adapter. The module plugs into the T-BERD/MTS-2000, T-BERD/MTS-4000 V2, T-BERD/MTS-5800, OneAdvisor 800 and FTH-9000 platforms, so the same fiber test capability can be moved between mainframes.

The 4100 Series modules are used to install, turn up and troubleshoot optical networks such as data center interconnection, metro, long-haul and FTTx/access links for wireless x-haul, as well as point-to-point and point-to-multipoint PON architectures. The single-port, three-wavelength approach lets a technician certify a link at construction and later verify that the fiber is ready for C- or L-band (xWDM) operation without changing ports. A test port health check runs with every acquisition, and permanent live traffic detection protects transmission equipment and avoids poor measurements on live fibers.

Analysis and workflow software

SmartLink Mapper (SLM) analyses the OTDR trace, identifies passive optical elements and displays them as icons in a link map with pass/fail information; the SmartLink, Trace and Table views are correlated so a selected event is highlighted in each. SmartTEST guides the user through setup, testing, result review and reporting in four steps. Optional mainframe software adds the FiberComplete PRO TrueBIDIR and Loopback bidirectional OTDR applications, Cable-SLM project management for high fiber count cables, and FTTH-SLM applications for PON architectures including unbalanced and tap couplers.

Light source and power meter

The module integrates a continuous-wave light source at the three OTDR wavelengths with 270 Hz, 330 Hz, 1 kHz and 2 kHz tone modulation. An in-line broadband power meter is available as a hardware option (E41OTDRPM), calibrated at 1310, 1490, 1550, 1625 and 1650 nm.
