Lower loss in general means fewer repeaters, and repeaters always add latency.

For this cable specifically, the optical signal spends significant time traveling through air, which has a lower index of refraction (higher signal speed) than the solid-glass cables in common use.

The article abstract claims a 45% improvement in signal speed, which would reduce latency over longer distances simply because the information arrives sooner.

Thank you.
