Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for New York City (40.71427, -74.00597) and Paris (48.85341, 2.34880). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 5,852.7 km |
| Vacuum RTT floor | 39.05 ms |
| Standard fiber RTT floor () | 57.31 ms |
| Low-latency fiber material floor | 57.08 ms |
| Engineering floor (5% path allowance) | 60.19 ms |
| Research 1.33× mapped-fiber reference | 76.23 ms |
| Estimated unamplified path loss | 1229.1 dB |
| Transparent optical spans / inline amplifiers | 77 / 76 |
| Published RTT inflation over fiber floor | 1.2× |
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.
