High-quality USB extenders and hubs do not reduce the data transfer rate from Time Taggers to the PC.

We tested several USB extenders using a Time Tagger X and Time Tagger Ultra, connected to a USB 3.0 port on a PC (CPU AMD Ryzen 9 5950X 16-Core 3.40GHz) with only essential background processes running. The maximum data transfer rates achieved aligned with the Time Tagger Specifications .


Recommended USB 3.x Extenders (Copper):
  • Lindy Active Extension Pro Series - available lengths: 8 / 10/ 15 / 20 / 30m
    E.g., 10m extender: Lindy 43157

Recommended USB 3.x Optical Extenders:

For galvanically isolated extenders, we tested the following model:

For lengths >= 100m, various other extenders exist, e.g.:


Time Tagger 20:

The Time Tagger 20 is powered via USB 2.0. Therefore, the USB extender must be powered as well to ensure a stable power supply. RJ45-based extenders have worked reliably with the Time Tagger 20 in our tests. We recommend the following model:
