Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for São Paulo (-23.54750, -46.63611) and Taipei (25.05306, 121.52639). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 18,818.5 km |
| Vacuum RTT floor | 125.54 ms |
| Standard fiber RTT floor () | 184.29 ms |
| Low-latency fiber material floor | 183.54 ms |
| Engineering floor (5% path allowance) | 193.52 ms |
| Research 1.33× mapped-fiber reference | 245.1 ms |
| Estimated unamplified path loss | 3951.9 dB |
| Transparent optical spans / inline amplifiers | 247 / 246 |
| Published RTT inflation over fiber floor | 1.42× |
Attenuation is used to estimate the number of 80 km optical spans; it does not directly slow light. See the full theoretical fiber latency, GeoNames, attenuation, and amplifier methodology.

About This Measurement
Published RTT reflects best-case backbone path behavior. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. Stability indicators are comparative estimates, and none of these values is an SLA.
