USB Extension Cable Latency

[Gyawdyr]

hi

 

does a usb extensioin cable add noticeable latency?

 

thanks

lets put it this way... i have a vive with a 60ft hdmi extension very little latence from that

not only that but i have a usb to cat5e running 100ft cat5e cable that then converts back to usb.... so basically a 100ft usb cable with 2 converters on it... very little lag. adds some but very little.

 

anyway to answer your question... under normal usb conditions like 5m or less i highly doubt you will notice much of a difference if any

Basically none, because signals move at near lightspeed through cables, so unless you care about the 1/150,000,000th of a second it takes the electricity to go through a 2 meter long extension, it shouldn't matter

The job of cables is to carry electrons from one end to the other. Electrons themselves move rather slowly, but push other electrons at the same rate. Imagine the cable was a 1 mile long hosepipe, and electrons were marbles. If you put one marble into the hosepipe, it would take a long time to get to the other end (or likely never when you factor in friction). But if it was jam packed full of marbles, it is almost instantaneous (at least to our perspective) to watch the marble fall out the other end the moment the new one was inserted. So there would be no conceivable lag as the increased distance doesn't use any kind of amplifier that would potentially delay the signal
