Datasheet

Overview

The VIAVI E4136A is the tri-wavelength member of the 4100 Series A OTDR modules. It tests at 1310, 1550 and 1625 nm from a single test port and is ordered with a PC or APC connector (E4136A-PC or E4136A-APC). 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 instruments.

The 4100 A variant offers an RMS dynamic range of 37 dB at 1310 nm and 36 dB at 1550 and 1625 nm, pulse widths from 5 ns to 20 µs, up to 256,000 acquisition points and a 0.7 m event dead zone. The EXTRANGE software option increases the RMS dynamic range of the 4100 A module. An integrated light source is available on the OTDR port, and an in-line broadband power meter can be added as a hardware option.

Single port for construction and maintenance

Combining three wavelengths on one port lets technicians switch between construction testing and troubleshooting without moving test leads. The 1625 nm wavelength supports bend detection and certifies a fiber for future C-band and L-band (xWDM) operation. Permanent live traffic detection avoids damage to transmission equipment, and an OTDR test port health check runs with every test to confirm good launch conditions. Results for all tested wavelengths are consolidated in a single report.

Analysis software and workflow

SmartLink Mapper (SLM) analyzes the trace, identifies passive optical elements and presents them as icons in a fiber link map with pass/fail information; the SmartLink, Trace and event table views are correlated so a selected event can be reviewed in any of them. SmartTEST guides the user through setup, testing, result review and reporting in four steps. Optional FiberComplete PRO applications add on-board bidirectional OTDR analysis (TrueBIDIR, patented) and two-fiber Loopback acquisition, Cable-SLM manages high fiber count cable projects, and FTTH-SLM tailors the OTDR application to PON architectures including unbalanced tap couplers. Automated batch testing with MPO-based multifiber switches supports up to 192 ports.

Test Process Automation

Test Process Automation (TPA) with StrataSync provides cloud-based job assignment, instant result submission through Job Manager, and automated data reporting for job close-out, team progress updates and network health analytics.
