Well it seems it has to do with cable length too? Today I ve used a 2m (instead of the 0.5m) cable of the same company and gave me an amber led.
Cable is
UBIQUITI NETWORKS UDC-2, UNIFI FIBER OPTIC DIRECT ATTACH COPPER CABLE SFP+ 10GBPS 2M (DAC) and due to it's specs
Connector LC-LC
Fiber Mode 50 / 125 μm
Fiber Type Duplex
Cable Jacket PVC
Cable Standard OM3
Insertion Loss ≤ 0.3 dB
Polish UPC to UPC
Jacket OD 2.0 mm
Wavelength 850 / 1310 nm
Jacket Color Aqua
Repeatability ≤ 0.1 dB
Durability ≤ 0.2 dB (1000 Times Mating)
Return Loss ≤ 50 dB
Operating Temperature -40 to 75° C
(-40 to 167° F)
it is a different one since it uses Fiber (light) as a cable and DAC transceivers.
PS Of course the cable is passive due the <5m length

I thought to help making a list with any third party vendors we came across and happened to play well with the aruba 1930 switch series.
Today i tried the 0,5m UBUQUITI UC-DAC-SFP+ (H21038018...) and the connection seemed ok. Leds on both switches are green and the connection established is 10Gbe
Feel free to include yours as well with brand / part number / length to have alternatives.
