Not really. I know of no cases where optical amplifiers posed a barrier to upgrading. Ciena and Infinera have been able to upgrade cable capacity by several X.
Optical amplifiers simply boost the signal. A photo is absorbed and then re-emitted with more power, but the same frequency and phase.
There is no optical/electrical/optical conversion.
