CMD/PD

Chromatic Mode Dispersion (CMD) and Polarization Dispersion (PD) is a crucial parameter for high-speed transmissions, notably for 100G and 400G Ethernet. This becomes even more crucial with the emergence of new transmission techniques involving PAM-4 Modulation and FEC-Technology utilizing QFSPs. To address these requirements, we offer single-ended testers such as the EXFO FTB-5700, as well as the classical approach using the BBS Broad Band Source and ODM Module from Viavi, ensuring accurate measurement and resolution of issues in high-speed transmissions.
