Viavi E4126MA3-APC OTDR Module

Overview

The Viavi E4126MA3-APC is the latest generation metro-access OTDR module in the 4100-Series platform, featuring 1310 nm and 1550 nm wavelength operation optimized for passive optical networks. The MA3 variant includes 256,000 acquisition points and advanced PON testing through 1x256 splitter configurations. Like the MA2, it provides combined single-mode and multimode capability in a quad module format with APC connectors, plus integration with intelligent optical application software for advanced network analysis and management.

Key Features

• Up to 45 dB dynamic range and 256,000 acquisition points for comprehensive fiber analysis
• PON-optimized to test through 1x256 splitter ratios
• Combined single-mode/multimode into one quad module
• Dual wavelength operation at 1310 nm and 1550 nm
• Integrated CW light source and power meter
• APC (angled) connectors for superior return loss characteristics
• Instant live traffic detection on active fiber (except live/filtered ports)
• ITU fiber type identification (G.65x A, B, C, and D) with water peak detection at 1383 nm
• Enterprise-SLM, FTTA-SLM, and FTTH-SLM intelligent optical software integration

Applications

• Fiber-to-the-Home (FTTH) and Fiber-to-the-Area (FTTA) network deployment with high splitter ratios
• Enterprise optical network testing with intelligent software-driven analysis
• PON maintenance and troubleshooting with live traffic detection
• Fiber characterization and water peak detection for system optimization
• Metro-access installations combining single-mode and multimode segments
• Field diagnostics on live optical networks without service disruption
