Relativity Networks raises $22M for faster fiber inside data centers

Reported 19 August 2026: Relativity Networks has raised $22 million to bring a faster class of fiber to data-center interconnect, targeting the link latency and bandwidth that constrain distributed training and inference clusters.

What it means Interconnect is the quiet ceiling on cluster scale — capital moving into fiber is a read on where the bottleneck is now, not where the GPUs are.
