Datasheet

Overview

The VIAVI E4138FC65-APC is a 4100 Series C-class OTDR module that combines 1310 nm, 1550 nm and a filtered 1650 nm wavelength on a single APC test port. It is delivered with an SC/APC test port adapter and 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 migrate between instruments.

The single-port, three-wavelength approach covers construction, maintenance and live-network troubleshooting with one tool. Technicians switch to the in-service filtered 1650 nm wavelength without moving test ports in the presence of live traffic, and the module also certifies that a fiber is ready for future C-band or L-band (xWDM) operation. Permanent live-traffic detection avoids damage to transmission equipment, and a test port health check verifies launch conditions before every acquisition.

The 4100 C variant provides up to 45 dB RMS dynamic range, up to 256,000 acquisition points, a distance display range up to 400 km and a 2.5 m attenuation dead zone. It is optimised for PON testing through splitters and, with the EPULSE3NS software option, supports a 3 ns pulse width. The datasheet also specifies its performance on hollow core fiber.

Software and workflow

Results are presented in SmartLink Mapper (SLM), Trace and Table views with direct correlation of the selected event. The SmartTEST assistant guides the user through setup, testing, review and reporting. Optional mainframe software adds TrueBIDIR instant bidirectional OTDR analysis, Loopback two-fiber bidirectional testing, Cable-SLM project management for high fiber count cables and FTTH-SLM applications for PON architectures. Test Process Automation (TPA) with Job Manager provides cloud-based job assignment and instant result submission.
