Overview

The VIAVI Optical Dispersion Measurement (ODM) module (8100 Series) 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, so all three tests run from a single fiber connection without swapping modules.

The CD, PMD and AP test functions are intended for network operators, fiber installers and dark fiber providers characterizing fiber systems. These include CWDM/DWDM systems with ROADMs and high-speed 10 GigE, 10 Gbps and 40 Gbps+ networks. VIAVI states that the solution supports deployment of 400G/800G links and the certification of both solid and hollow core fibers.

Measurement methods

CD is measured with a patented phase-shift method, and PMD with the fixed analyzer method. The module covers the 1260 to 1640 nm wavelength range. It works with VIAVI broadband light sources: the E81BBS2A broadband source module or the SmartClass OBS-500/550 handheld sources. Using the OBS-550 in High Dynamic mode extends the dynamic range.

Versions

The module comes in a Long Range (81LRODM2) version and a Medium Range (81MRODM2) version, each available with an APC or PC connector. The two versions differ in wavelength acquisition range, dynamic range and measurement time.
