Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for Sydney (-33.86785, 151.20732) and Berlin (52.52437, 13.41053). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 16,087.7 km |
| Vacuum RTT floor | 107.33 ms |
| Standard fiber RTT floor () | 157.54 ms |
| Low-latency fiber material floor | 156.91 ms |
| Engineering floor (5% path allowance) | 165.44 ms |
| Research 1.33× mapped-fiber reference | 209.53 ms |
| Estimated unamplified path loss | 3378.4 dB |
| Transparent optical spans / inline amplifiers | 212 / 211 |
| Published RTT inflation over fiber floor | 1.59× |
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.
