Surge in submarine-cable landings enabling low-latency coastal hubs

Google’s trans-Pacific cable and Cirion’s SAC2 system are elevating Valparaíso and Fortaleza into latency-sensitive exchange points. Fortaleza now hosts 16 live cables, letting operators deliver sub-60 ms round-trip times to Miami, Luanda, and Lisbon. These facilities deploy dense optical cross-connects and automated fiber monitoring to handle traffic peaks during live-stream events and gaming launches.

Increasing network complexity

Hybrid-cloud overlays, east-west microsegmentation, and edge bursts expose skill gaps. Enterprises deploying intent-based controllers face multi-vendor API sprawl that strains thin NOC teams. Lack of trained staff delays 400G adoption schedules, inflates consulting reliance, and limits achievable automation depth.

High import tariffs & CAPEX for advanced equipment

Tariffs pushing costs 8–20% higher for routers and leaf switches persuade smaller operators to extend life cycles rather than embrace 800G optics. Brazil’s ex-tariff program counters part of this penalty by exempting 1,495 ICT SKUs from duties, accelerating availability of AI-optimized NICs that are not manufactured domestically.
