Viavi E4126MA2-APC OTDR Module

Overview

The Viavi E4126MA2-APC is an enhanced metro-access OTDR module within the 4100-Series platform, operating at 1310 nm and 1550 nm wavelengths. The MA2 version features increased acquisition capabilities with 256,000 acquisition points and improved PON testing optimization through 1x256 splitter ratios. The APC (angled connector) variant is designed for angled physical contact connectors, improving return loss performance in demanding optical network environments.

Key Features
