Right. A lot going on here. How can network operators best manage CD and PMD?
Operators use several techniques:
n Compensators and Modulation Techniques: Advanced modulation techniques, negative chirping, forward error correction (FEC), and digital signal processing (DSP) in coherent transceivers help manage dispersion. n Proper Fibre Characterisation: Comprehensive CD and PMD testing before activating services ensures network integrity and readiness for technological advancements. What makes full fibre characterisation so critical at the moment? With the rise of data centres, advancements in AI, faster network speeds and bandwidth-intensive applications like telehealth and video conferencing, managing CD and PMD is essential for high-speed network performance and reliability. I hear EXFO’s FTBx-570 single- ended dispersion analyser might help network operators; tell me HOW. The FTBx-570 provides fast, single-ended CD and PMD testing, supporting speeds up to 800G. It ensures service integrity across various network types and reduces deployment time and operational costs by allowing technicians to characterise multiple optical links from a single location in less than 30 seconds.
