Explore Los Angeles, USA to São Paulo, Brazil ICMP RTT, jitter, packet loss and fiber latency limits on the AS203314 network.

🇺🇸 Los Angeles, USA (LAX) → 🇧🇷 São Paulo, Brazil (GRU)

Measurement round: 2026-08-16T04:07:28Z.

Los Angeles to São Paulo averaged 131.3 ms across 50 replies. The observed range was 125.74 to 147.12 ms; these figures describe one probe round, not a long-term service target.

Standard deviation was 4.94 ms, or 3.8% of the average. This describes variation within the sample without identifying its cause.

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 131.3 ± 0.70 ms (SE)

Sample distribution: box = interquartile range (128.1–132.9 ms), median 129.9 ms · whiskers = min–max · diamond = round average · each dot is one measured sample.

How to read this chart

The shaded band spans the measured minimum to maximum RTT of all samples collected up to that point, and the thin line traces the running average. The final position therefore matches the round statistics exactly. The band only widens when a new extreme sample arrives.

The dashed line is the round average, and the shaded band at the bottom is the theoretical fiber-optic floor (96.9 ms) for this route.

Theoretical Fiber Latency

The propagation model uses public city-centre coordinates from GeoNames: Los Angeles (34.05223, -118.24368) and São Paulo (-23.54750, -46.63611). These are not facility coordinates or a surveyed cable path.

Physical Reference	Value
WGS-84 geodesic distance	9,894.5 km
Vacuum RTT floor	66.01 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	96.89 ms
Low-latency fiber material floor	96.51 ms
Engineering floor (5% path allowance)	101.75 ms
Research 1.33× mapped-fiber reference	128.87 ms
Estimated unamplified path loss	2077.8 dB
Transparent optical spans / inline amplifiers	130 / 129
Published RTT inflation over fiber floor	1.36×

The span count assumes 80 km optical spans. Attenuation is a power-loss term, not a propagation delay. See the model assumptions and equations.

About This Measurement

These ICMP measurements cover the two backbone endpoints. Access networks, routing policy and load can change an end user's result. A probe round is not an SLA.
