Polarization and Dispersion Analysis

Chromatic dispersion (CD) and polarization mode dispersion (PMD) hamper transmission in high-speed networks. They can also threaten the integrity of the signal at 10 Gbit/s and 40 Gbit/s, which in turn affects the quality of service (QoS). Essentially, they are speed-limitating phenomena.

How to select the right dispersion solution for your needs?

1. What typical link distance do you need to qualify?
2. Do you need to compensate for a single section, or are there cascaded compensators?
3. What transmission rate are you currently using? What rate will you be using in the future?

With the broadest dispersion portfolio on the market, we can help you address these questions.
