Datasheet

Overview

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

Combining the CD, PMD and AP test functions allows network operators, fiber installers and dark fiber providers to characterize fiber systems, including CWDM/DWDM systems with ROADM and high-speed networks. A single connection is used for all three measurements, so no module switch-over is required during the workflow.

CD is measured with a patented phase-shift method and PMD with the fixed analyzer method. The module works with a broadband source, either the E81BBS2A broadband source module or the SmartClass OBS-500/550 handheld broadband sources, and supports both standard single-mode fiber and hollow core fiber.
