15ft USB 3.0 A Male to A Female Active Extension Cable
Take USB 3.0 to new lengths with this USB 3.0 Active Extension Cable from Monoprice!
With data transfer rates up to 10 times faster than USB 2.0, USB 3.0 is quickly gaining in popularity. However, although it has a higher voltage and current level, passive cables are still limited to a maximum length less than 15 feet.
This Active Extension Cable draws power from the USB 3.0 bus and uses it to boost and regenerate the data signals, ensuring that full SuperSpeeds can be maintained to much longer lengths. By combining two of these extension cables with a 3 meter passive cables a total length of 13 meters (42.6 feet).
This 5 meter (16.4 foot) cable is backwards compatible with all previous USB versions and any USB equipped device. It has a USB 3.0 A male connector on one end and a USB 3.0 A female port on the other end. Per the USB 3.0 spec, the plastic inside each connector is colored blue to distinguish it from connectors designed for previous USB versions.
Questions and Answers
Ignore the reviews that state "it won't power my device" blah, blah...
I went through many "passive" (regular) USB extension cables before purchasing this "Active" USB 3 cable.
I tried to avoid using "active" cables due to the difference in price from the non-active cables.
Big mistake. You cannot have a USB cable longer that about 9-10 feet (usually 9) before you start having serious errors if the cable works for your device at all.
Too many people are buying the cable and trying to run USB devices that can be powered by the USB power.
YOU CAN NOT DO THAT ON AN ACTIVE CABLE! The reason the cable is active is because it's USING the power from the USB3 port to run a repeater in the cable. This is what makes it capable of being the length it is without a problem.
You therefore can only use this USB cable with:
1) Devices that require extremely low power (e.g. USB memory sticks)
2) Externally Powered USB HUBS
That's how it's SUPPOSED to work.
I placed my SiiG USB 3 externally powered Hub on the end of this cable and connected a Rosewill UASP capable HDD enclosure with a 3TB SATA III drive installed. It recognized the USB3 Hub, and the drive, and then my PC connected to the SATA III Drive using UASP ove USB 3 and the speed was BLAZING fast, as expected.
Of course all other USB devices worked flawlessly too. Many WITHOUT the powered hub.
(Of course all those devices were VERY low power USB memory sticks.)
PROS: This cable is very well built and generally high quality.
Excellent, firm connectors.
CONS: Too many people review this cable as "poor" or "so-so" because they don't understand how USB works, or the power requirements for their USB devices and what it means to USB power when you use an "ACTIVE" cable.
(Which at these lengths, you -must- use an active cable for USB 3 devices to work correctly!)
I rebooted once or twice but Oculus is happy with my three sensors with a fourth on the way.

So I talked to monoprice tech support. They suggested I might have a defective cable and sent another one, but my results were exactly the same. Is anyone using this monoprice cable successfully with a portable USB 3 drive that relies on USB for power as well as data transmission? I doubt it. But if somebody is, I’d like to know what portable USB drive they’re using and what it’s connected to.
The good news here is that the monoprice cable works flawlessly with drives that have a power supply. Read and write speeds don’t suffer a bit (same as without the cable, in repeated tests.) The bad news is that this capability is worthless to me I need to connect a portable USB 3 drive, and there’s not even an option to add an AC adapter to the drives I’m using. So I wasted about $15 on this, as well as the time involved in verifying the cable’s limitations.
Monoprice should really include a disclaimer in the product description that the cable may not work with portable drives that are powered via USB instead of their own power supply that’s assuming there is one person on this planet, somewhere, with a portable drive that does work with the Monoprice cable. Otherwise, they should just say it will not work. Or maybe stop selling it, unless/until there is better product available.
PROS: Works fine if USB drive has its own power supply.
CONS: Won't work if drive relies on USB for power.
1) It gets 140 MB/sec when connected directly to my PC.
2) It gets 140 MB/sec when connected to EITHER of the two extension cables.
3) It gets 140 MB/sec when plugged into my USB 3.0 HUB, which is connected to EITHER cable.
4) If both cables are chained and it's plugged directly into the second cable, it gets ~50MB/sec when it works, but usually the test fails. Windows constantly shows the device being removed and inserted. You can't access the device for more than about 3 seconds at a time.
5) Same setup as 4 above, but with my powered USB 3.0 hub connected to the second cable yields the exact same results as 4.
Maybe one of my cables is bad, but that's hard to believe since they both work fine independently. I think Monoprice got ahead of themselves on the marketing here.
PROS: One of these cables works great. Tested against a Transcend JetFlash 780, I saw a consistent 140 MB/sec, which is exactly what the drive performed at when connected directly to the PC.
CONS: The description says: "By combining two of these extension cables with a 3 meter passive cables a total length of 13 meters (42.6 feet)." This is absolutely not true (even if you don't have a passive cable in the chain), which is why I left the low rating.
PROS: This cable is of good quality and value. Performs well and met expectations.
PROS: Does excactly what it is supposed to do.
PROS: Cable build.
CONS: Female active port does not assure a snug fit.
PROS: Great length and quality
PROS: works with, usually difficult to match, sony wifi range extender. effective and affordable.
CONS: i only needed one
CONS: Product does not work with PS3, while it detects the PS3 and the blue light is on on the PS3 camera, you cannot use with move controller.
