The growing demand for computing power and new AI applications are forcing data centers to become more space-efficient. A new generation of Very Small Form Factor (VSFF) fiber optic connectors triples the port density on the patch panel.

AI applications generate massive data throughputs and distributed access. This load primarily affects hyperscalers and high-performance computing (HPC) data centers, but is increasingly impacting colocation and enterprise data centers as well. The logical consequence at the infrastructure level is the transition to transmission speeds of 400G and 800G—initial implementations are already targeting 1.6T, with future targets set at 3.2T.
