This cable has USB on one end and an ethernet-like connector on the other.

The print on the cable reads:

USB 2.0 Shielded High Speed USB 28 1P 26 2C E52534 D AWM

I want to know the purpose of the cable.

Let me know if you need to know the color coding of the ethernet-side.

"ehternet like thing"? high res Picture would help – Moab Nov 23 '11 at 0:49
Could be a USB data cable for a (APC) UPS, they use a cable like that. Like others have said, we need a picture or we're just guessing. – Ƭᴇcʜιᴇ007 Nov 23 '11 at 1:08
@AndrejaKo are you saying you are guessing what the cable looks like and adding a picture of your guess? How do you know the male/female orientation of either end? – Paul Nov 23 '11 at 1:32
@AndrejaKo We really need a picture of the actual cable from the OP to give an accurate answer. Preferably, one that clearly shows the pin-out on the RJ-45 end. – Iszi Nov 23 '11 at 4:25

As @Techie007 says, it is an APC USB data cable in the picture. It connects to an RJ45 port on the UPS and the USB port on the computer. Common on some small business products and higher end home products from APC

I can confirm this, this is the cable that came with my APC brand UPS. It's not USB-to-serial, but an HID-class USB device. Requires "PowerChute" software on Windows and "apcaccess" on Linux. – LawrenceC Nov 23 '11 at 1:35
Note that the cable pictured is not the OP cable – Paul Nov 23 '11 at 1:40
@Paul We don't know for sure! I'm in an enviroment with 20+ APC UPS' of different models and the description matches many of the cables... :) – HaydnWVN Nov 23 '11 at 16:23
@ultrasawblade, what does the cable do?! I mean a cable like that for a power supply? what's the purpose? – TPR Nov 25 '11 at 1:31
It lets you get readings from the power supply, i.e. current watts being pulled, minutes left on battery, whether it's getting wall power or not, etc. – LawrenceC Nov 25 '11 at 6:29
