Notable capabilities and operational notes

• In‑service troubleshooting: Dedicated wavelengths (e.g., 1625 nm) and instantaneous traffic detection let technicians connect to live fibers for troubleshooting without taking services down.
• Single‑port convenience: The module’s single connector for multiple wavelengths reduces the need for patch cords and simplifies field workflows.
• Automated fiber qualification: When used with the 4100‑Series FiberComplete option, the module can run bidirectional IL/ORL and OTDR tests in one automated sequence to produce pass/fail results and reports.

When to choose the 4126 MA module

• You need a handheld, field‑portable OTDR optimized for access and PON networks.
• You require in‑service testing capability (live‑fiber detection and 1625 nm) and PON splitter support.
• You want integrated IL/ORL/OTDR workflows (FiberComplete) and fast report generation on a T‑BERD/MTS handheld platform.
