Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and Hong Kong (22.27832, 114.17469). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 810.3 km |
| Vacuum RTT floor | 5.41 ms |
| Standard fiber RTT floor () | 7.94 ms |
| Low-latency fiber material floor | 7.9 ms |
| Engineering floor (5% path allowance) | 8.33 ms |
| Research 1.33× mapped-fiber reference | 10.55 ms |
| Estimated unamplified path loss | 170.2 dB |
| Transparent optical spans / inline amplifiers | 11 / 10 |
| Published RTT inflation over fiber floor | 1.89× |
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.
