Datasheet

Overview

The VIAVI E81LRODM2-PC is the long range version of the Optical Dispersion Measurement (ODM) module for the OneAdvisor 800 platform, fitted with a PC optical connector. It is a compact, single test port field module that combines Chromatic Dispersion (CD), Polarization Mode Dispersion (PMD) and Attenuation Profile (AP) measurements in one unit, so all three tests are performed from a single fiber connection without switching modules.

CD is measured with a patented phase-shift method and PMD with the fixed analyzer method. The long range module acquires over the full 1260 to 1640 nm wavelength range and offers the higher dynamic range of the two ODM variants, which allows it to characterize buried, aerial and submarine cables, amplified and non-amplified links, and short to ultra-long haul spans. Measurement times are short: a complete CD/PMD/AP sequence takes less than two minutes.

The module works together with a broadband source placed at the far end of the fiber, either the E81BBS2A module for the OneAdvisor 800 or the handheld SmartClass OBS-500/550 light sources. Specifications are given with the E81BBS2A source unless stated otherwise; the OBS-550 in High Dynamic mode extends the dynamic range further.

Together with the CD, PMD and AP results, network operators, fiber installers and dark fiber providers can qualify CWDM/DWDM systems with ROADMs and high-speed links up to 400G/800G and beyond, and the module is also used to certify hollow core fiber for medium and long range applications and data center interconnects.
