Singapore, Singapore to Paris, France: ICMP RTT measurements with latency, jitter, packet loss, and fiber-efficiency metrics for this route.

🇸🇬 Singapore (SIN) → 🇫🇷 Paris, France (PAR)

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

For measurement round 2026-08-15T04:03:13Z, ICMP echo RTT from Singapore to Paris averaged 149.3 ms over 50 samples, with a minimum of 141.07 ms, a maximum of 173.79 ms, and no packet loss. Jitter was 5.7 ms and the standard deviation was 7.35 ms, giving a variability-to-average ratio of about 4.9 percent.

Over a geodesic distance of 10,741.6 km, the measured average is 1.42 times the 105.19 ms fiber-floor estimate, which corresponds to 70.5 percent fiber-floor efficiency. The route ranks 8th among the 19 routes recorded for the same source, placing it mid-pack for average latency; the 3.08 percent median variability for that route set is lower than this route's observed 4.9 percent spread.

With a latency tier of Good and zero lost probes, the Paris path offers a useful balance across a long intercontinental distance, though its above-median variability remains the metric most worth monitoring.

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 → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 149.3 ± 1.04 ms (SE)

Sample distribution: box = interquartile range (143.9–152.1 ms), median 147.0 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 (105.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	10,741.6 km
Vacuum RTT floor	71.66 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	105.19 ms
Low-latency fiber material floor	104.77 ms
Engineering floor (5% path allowance)	110.46 ms
Research 1.33× mapped-fiber reference	139.9 ms
Estimated unamplified path loss	2255.7 dB
Transparent optical spans / inline amplifiers	141 / 140
Published RTT inflation over fiber floor	1.42×

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.
