Anyone use DAC cables with a Cisco 55XX Wireless Controller?

I am wondering if anyone has used DAC cables on a 5500 series WLC. We our moving ours and would like to replace the fiber uplink with DAC. Here's what TAC has to say:

In regards to the question about DAC cable support on the 5508 WLC, please make sure that those cables provide an equivalent interface to the following SFPs, which are the only ones supported by the WLC:

The Gigabit Ethernet ports on the Cisco 5508 Controllers accept these SX/LC/T small form-factor plug-in (SFP) modules:
- 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network through an 850nM (SX) fiber-optic link using an LC physical connector
- 1000BASE-LX SFP modules, which provide a 1000-Mbps wired connection to a network through a 1300nM (LX/LH) fiber-optic link using an LC physical connector
- 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector
