Overview
The VIAVI E4126C is the dual-wavelength 1310/1550 nm member of the 4100 C class of OTDR modules in the 4100 Series. It is ordered with either a PC or APC test port (E4126C-PC / E4126C-APC) and 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 these platforms.
The 4100 C variant offers 45 dB RMS dynamic range at 1310 nm and 1550 nm, a 0.65 m event dead zone, a 2.5 m attenuation dead zone and a distance display range of 0.1 up to 400 km. Pulse widths from 5 ns to 20 µs are standard, with a 3 ns pulse width available through the EPULSE3NS software option. Up to 256,000 acquisition points can be recorded. The module also includes a 1310/1550/1625 nm light source function on the OTDR port and can be fitted with an in-line broadband power meter hardware option.
The module is operated through the platform's touch-gesture user interface. SmartLink Mapper (SLM) analyzes the OTDR trace and represents passive optical elements as icons in a link map, with direct correlation between the SmartLink, trace and event table views. SmartTEST guides the operator through setup, testing, result review and reporting in four steps. A test port health check runs with every acquisition, and permanent live traffic detection avoids damage to transmission equipment.
Bidirectional and high fiber count testing
With the FiberComplete PRO software options, the module supports TrueBIDIR real time bidirectional OTDR analysis on the instrument (patented) and a Loopback mode for two-fiber bidirectional acquisition. TrueBIDIR also supports hollow core fiber testing with a single unified acquisition workflow. The Cable-SLM option manages high fiber count cable projects, and automated batch testing is possible with MPO-based multifiber switches up to 192 ports. Test Process Automation (TPA) provides cloud-based job assignment and instant result submission through Job Manager.
