In this week's Friday Five, we  track how Grain Management's move to combine Great Plains Communications and Ritter under the Rightfiber brand reflects private equity's growing role in fiber M&A. Meanwhile, Cogent and Uniti ramp wavelength services and TDS advance FTTH.

This seminar explores the real-world considerations of migrating to 800G in DWDM and OTN environments. Attendees will learn how 800G impacts fibre capacity, how to navigate upgrades within existing brownfield networks, and what practical migration strategies are available, including flex-grid architectures.
