ICMP round-trip time data for Singapore, Singapore to Los Angeles, USA: average, minimum, maximum latency, jitter, packet loss and fiber efficiency.

🇸🇬 Singapore (SIN) → 🇺🇸 Los Angeles, USA (LAX)

Measurement round: 2026-08-16T04:07:28Z.

During the 2026-08-16T04:07:28Z round, 50 ICMP echo probes from Singapore to Los Angeles, USA averaged 168.2 ms, with a minimum of 160.69 ms, a maximum of 194.08 ms, and no packet loss. Jitter was 4.76 ms and the standard deviation 6.01 ms, showing very consistent packet timing in this sample.

The average is 1.22 times the 138.43 ms fiber-floor estimate for a 14,135.8 km great-circle distance, yielding an 82.3% fiber efficiency. This route ranked 14th among the 19 routes measured from this origin in the same round; typical variability across that set was 3.28% of the average RTT, while the standard deviation here is about 3.6% of the mean.

The useful takeaway is that the gap between the minimum and maximum RTT is 33.39 ms, and the minimum sits just 7.51 ms below the average, so most measurements cluster near 168 ms. With zero packet loss and a fair latency tier, this trans-Pacific route is consistent and close to the fiber floor.

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 → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 168.2 ± 0.85 ms (SE)

Sample distribution: box = interquartile range (164.8–170.5 ms), median 166.5 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 (138.4 ms) for this route.

Vacuum RTT floor	94.3 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	138.43 ms
Low-latency fiber material floor	137.87 ms
Engineering floor (5% path allowance)	145.37 ms
Research 1.33× mapped-fiber reference	184.11 ms
Estimated unamplified path loss	2968.5 dB

Published RTT inflation over fiber floor	1.22×

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.

Per-pair files are available at /opendata/latency/latest/pairs/sin-lax.pings.{csv,json,yaml}.
