I-PMD Measurement

Chapter 11
This chapter describes the different steps in carrying out an In-Service and In-Band
PMD-OSNR with a T-BERD/MTS 8000 V2 equipped with 81IPMD and 81PSM Modules.
Viavi's non-intrusive technique used in I-PMD enables to measure PMD in a link that is
in-service by using the transmission DWDM channels.
Viavi unique I-PMD test solution allows troubleshooting faulty channels of 10G / 40G
transmission systems and qualifying fiber networks for future upgrade plans up to 100G
without turning the entire network down.
This chapter refers exclusively to I-PMD measurement.
