Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for Frankfurt am Main (50.11552, 8.68417) and Tokyo (35.68950, 139.69171). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 9,354.4 km |
| Vacuum RTT floor | 62.41 ms |
| Standard fiber RTT floor () | 91.61 ms |
| Low-latency fiber material floor | 91.24 ms |
| Engineering floor (5% path allowance) | 96.2 ms |
| Research 1.33× mapped-fiber reference | 121.84 ms |
| Estimated unamplified path loss | 1964.4 dB |
| Transparent optical spans / inline amplifiers | 123 / 122 |
| Published RTT inflation over fiber floor | 2.14× |
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.
