Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and Singapore (1.28967, 103.85007). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 3,243.9 km |
| Vacuum RTT floor | 21.64 ms |
| Standard fiber RTT floor () | 31.77 ms |
| Low-latency fiber material floor | 31.64 ms |
| Engineering floor (5% path allowance) | 33.36 ms |
| Research 1.33× mapped-fiber reference | 42.25 ms |
| Estimated unamplified path loss | 681.2 dB |
| Transparent optical spans / inline amplifiers | 43 / 42 |
| Published RTT inflation over fiber floor | 1.4× |
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.
