Well sending serial will be much better over longer lengths than mass storage data transfer but the max length for USB 1. USB 1. Although a single cable is limited to 5 metres, the USB 2. This allows for a maximum distance of 30 metres 98 ft between host and device, using six cables 5 metres 16 ft long and five hubs. The best answers are voted up and rise to the top.

Our cable has a quite good quality though. Add a comment. Active Oldest Votes. R Drast R Drast 4, 13 13 silver badges 18 18 bronze badges. The 15m limit is for RS especially at the low voltage levels commonly used by modern PCs. You probably get further if you could use the entirely-within-RSspec 15 Volt. So the lower the capacitance, less is voltage drop and longer the distance we can pass? Then I read the spec. I am glad you found peace with the interface specification.
Transformer or optically isolated line drivers are the way to go for distance, company I worked for made a range and sold them to the banks for ATMs as the imported line drivers were not isolated and failed under harsh African conditions lightning, dirty mains. They did 2 km with synch comms at and failed only with significant lightning incidents but protected the end equipment.

RS is in many ways more sensitive to bad grounds as it has lower common mode voltage limits and is often implemented without a common ground wire which is not good unless it is galvanicly isolated. UTP Ethernet is nice because it is transformer isolated differential signalling.
Communication protocols like USB include strategies for mitigating the effects of signal distortion. USB and Thunderbolt Compared.

No attempt is made to boost or regenerate the signal so passive cables are susceptible to the problems of attenuation and noise described above. However, buying a good quality cable with thicker gauge copper conductors and better shielding will allow you to modestly extend signal transmission beyond the recommended maximum distance.
Consider an Active USB Cable Active cables include circuitry, usually at the receiving end, that regenerates the signal and enables data to be transmitted over longer distances. Active cables can be daisy-chained so long as power is available for each transceiver in the chain.
