ICMP RTT measurements from Singapore to Frankfurt, Germany: average latency, jitter, packet loss and route efficiency for the 2026-08-15T04:03:13Z round.

🇸🇬 Singapore (SIN) → 🇩🇪 Frankfurt, Germany (FRA)

Measurement round: 2026-08-15T04:03:13Z.

Singapore to Frankfurt produced a 152.7 ms average ICMP RTT in round 2026-08-15T04:03:13Z, from 50 samples with a minimum of 150.31 ms, a maximum of 162.48 ms, 1.81 ms jitter, and zero packet loss. The spread from minimum to maximum was only 12.17 ms, indicating very stable transit during the test window.

The observed RTT is 1.52 times the fiber floor, or 65.9% fiber efficiency, so the measured latency is moderately above the direct fiber bound. The 68.5 ms vacuum floor and 100.56 ms fiber floor frame the physical limits; the measured 152.7 ms is well above those bounds but consistent for an intercontinental route.

Among the 19 routes leaving this Singapore origin, this route ranks 9th by average RTT. Its 2.36 ms standard deviation is only about 1.5% of the average, well under the network median of 3.08%, making the route's consistency its standout feature for network engineering.

Ping Measurement Series

The chart below renders the 50-sample ICMP echo measurement round for this route; an accessible table of every sample is included with the chart.

Ping series: SIN → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 152.7 ± 0.33 ms (SE)

Sample distribution: box = interquartile range (151.1–153.4 ms), median 152.3 ms · whiskers = min–max · diamond = round average · each dot is one measured sample.

How to read this chart

The shaded band spans the measured minimum to maximum RTT of all samples collected up to that point, and the thin line traces the running average. The final position therefore matches the round statistics exactly — the band only widens when a new extreme sample arrives.

The dashed line is the round average, and the shaded band at the bottom is the theoretical fiber-optic floor (100.6 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Frankfurt am Main (50.11552, 8.68417). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	10,268.5 km
Vacuum RTT floor	68.5 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	100.56 ms
Low-latency fiber material floor	100.15 ms
Engineering floor (5% path allowance)	105.6 ms
Research 1.33× mapped-fiber reference	133.74 ms
Estimated unamplified path loss	2156.4 dB
Transparent optical spans / inline amplifiers	135 / 134
Published RTT inflation over fiber floor	1.52×

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 measured with ICMP echo probes between PoPs. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. None of these values is an SLA.
