Meta operates one of the largest global optical backbone network to support its business across social media, AI training, virtual/augmented reality, etc.

The rapid traffic growth on the network leads to significant network design challenges in how to support this growth with limited space/power/cost budget.

To address these challenges, we proposed a set of strategies to evolve our backbone network towards a point-to-point architecture, also implementing ZR optics to achieve high efficiency gains in fiber and site investments.
