How to Extend yout USB using UTP

Step 2: The making of Part 1

Open the UTP and USB cable. Put the small PVC pipe in the UTP cable. Put the thermofit in the USB cable. Then connect it like this:

white orange & orange to red,
white & green to white,
green to green,
and the rest to black.

Remeber to solder it.

can I use two lines to power a USB hub on the side of the female USB port ?

The correct colors for any CAT 5 or CAT 6 cable are

1. slate-orange
2. orange
3. slate-blue
4. blue
5. slate-green
6. green
7. slate-brown
8. brown

I'm using a CAT 5e cable as well... so what color combination should I use to connect this to the usb cabling?

[mmariappan]

thanks its superb!!!!!!!!!!!!!!!!!!!!!!!!
works nicely

I am from tamilnadu, india

[egomez18]

It works perfectly. Later I will give details of how that works best with the same UTP cable. Thank you very much for your idea.

it's work for flash drive but i use with usb wireless 2.0 not work how can i do next ?

[forkber]

It work on a 7 meters (23 feet) CAT6 cable! use a twisted pair for the D+ D- USB and another for the power (black and red on Usb cable) I use it with a HD multimedia player at full speed (USB 2) Tanks

The wires of the Utb cable can you draw it more detalied to be connected the rightway

[sagewifi]

Is there a reason you bound those colors? Is red and blank on the USB - power and ground? I guess you want more copper (2 or 3 UTP wires) for power and ground than the signal wires? I did something similar with DIY PoE to my roof. Thanks- Great for USB webcams.

I suggest instead of using only one wire, use instead a pair for each usb pin, this will lessen the impedance, and grant good stability in connections. I know better, I did a 50-feet cable like that, testing hard and exhaustively.

[Danicek]

Using 2 Pairs for supply voltage is good idea. But do not use it for signal path.

[CrudeBuster]

Um, why not? If twisted pair is good for Ethernet TX / RX, why wouldn't be good for USB D+/D-?

[Danicek]

For DC supply you need lownest possible resistance in path. So it is good idea use one pait as +5V and other pair as GND, AC charakteristic is not so important.
On other hand, we can almost omit currents in signal path, at least for USB, because there is no termination. For signal path parameters is important AC point of view. And in this case bigger "volume' of cable will make bigger condensator to charge/discharge -> bigger looses on higher frequencies.
So.. use 1 and half pair for +5V, another 1.5 pair for gnd and 1 pair for D+ and D-.

BTW. for 100Mbit ethernet
1 pair = TX+, TX-
1 pair = RX+, RX-
2 pairs unused (used for 1Gbit ethernet)

[CrudeBuster]

But as the theoretical limit of USB data signal wiring is 5 meters, we're trading loss in high frequency for stability, lessening the impedance. Well, I'll test your suggestion anyway, because I'm having problems with different USB controllers, some do accept the extension over 10m, others don't get even 4m.

[CrudeBuster]

The alternate wiring using 1 pair and a half for +5 and GND functioned very well, kudos for you for the tip, Danicek.

Even in my EEEPc, where the pair wiring didn't worked after 2m, 10m using the alternate worked like a breeze with my mouse and mp4 player, as well as the Encore USB dongle.

I used this particular wiring colors:
Orange pair + White/Light Blue = +5
Maroon pair + Dark Blue = GND
Dark Green = +D
White/Light Green = -D

The +5 measured 5.05 with the mouse working, the alternate wiring kept the loss really down.

THIS WORKED PERFECTLY WITH MY BELKIN F5D8053 N BAND USB WIFI ADAPTOR AND OVER 35FT OF CAT 5 CABLE!!! I DID HAVE TO PLUG IT INTO MY USB 1.0 HUB AND NOT THE USB 2.0 PORTS ON MY DESKTOP TO GET IT TO WORK RIGHT . I HAVEN'T NOTICED ANY SIGNAL LOSS AND IT SAVED ME AT LEAST $50 IN CABLES AND USB REPEATERS. THANKS A LOT.

It Works !!
Although I only needed 14Mts… did not work until I connected the cable UTP CAT3 (Is possible that is better with the CAT6) directly to the card of the Webcam to omit the ferrite nucleus through which the cable original passes (In my case, the image was not deteriorated). Perhaps confución with the order of the connection of cables has appeared. They must be:

---

White/orange + orange to red
white to white
green to green
the rest to black
