Datasheet

Overview

The VIAVI E81MRODM2-APC is the medium range version of the Optical Dispersion Measurement (ODM) module (8100 Series) and has an APC connector. It is a compact field test module for the OneAdvisor 800 platform. It combines Chromatic Dispersion (CD), Polarization Mode Dispersion (PMD) and Attenuation Profile (AP) measurements in one module with a single test port.

Because all three tests run from one connection, the technician does not have to swap modules between tests. CD is measured with a patented phase-shift method and PMD with the fixed analyzer method. The module works with VIAVI broadband sources, including the E81BBS2A broadband source module and the SmartClass OBS-500/550 handheld sources.

The module is intended for characterizing fiber in high-speed networks, including CWDM/DWDM systems with amplified links, transport, metro, mobile backhaul and medium-haul links, and data center interconnects. It supports standard SMF 9/125 µm fiber as well as hollow core fiber. Combining the results of all three test parameters can help identify unknown fiber types.
