The document discusses moving HFC actives towards 1.8 GHz and the capacity boost that DOCSIS 4.0 and higher bandwidths will provide over coaxial cable. It also notes that 1.8 GHz amplifier designs are ready for the next frequency splits and increased bandwidths, though cable system upgrades will depend on factors like cable lengths, drop cable losses, and legacy systems.

Summary
2. DOCSIS 4.0 brings more capacity
1. Coax is a powerful asset
3. 1.8 GHz amplifiers are ready just around the corner
• But when do upgrades make sense?
• Cable lengths, drop cable losses, legacy systems,
in-house networks, etc.
4. In practice
• Trials can start in 2021
• 1.8 GHz amplifiers are waiting DOCSIS 4.0 devices,
not vice versa
5. In coax we trust!
