Frankfurt to Singapore, Germany to Singapore ICMP round-trip time: 50-sample latency, packet loss, jitter and route efficiency metrics.

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

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

During the 2026-08-15T04:03:13Z round, 50 ICMP echo requests from Frankfurt to Singapore averaged 153.2 ms, with a minimum of 147.83 ms and a maximum of 167.15 ms. Zero packets were lost, the standard deviation was 4.22 ms, and jitter sat at 3.68 ms.

The physical distance of about 10,268 km implies a fiber floor of 100.56 ms; the observed average is 1.52 times that floor, or about 65.6% fiber efficiency. The result is a realistic 150 ms-class RTT baseline for this route.

Among the 19 measured routes this path ranks 13th, and its 2.75% variation around the average is below the 3.08% median spread-to-average ratio for the set. Frankfurt-to-Singapore latency is therefore both mid-tier and highly stable, with no packet loss in this sample.

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: FRA → SIN

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 153.2 ± 0.60 ms (SE)

Sample distribution: box = interquartile range (149.8–155.3 ms), median 152.2 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 Frankfurt am Main (50.11552, 8.68417) and Singapore (1.28967, 103.85007). 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.
