DIfferenct between twinax cables (SFP-10G-AOCxxx vs SFP-H10GB-ACUxxx)

[HumanTorch]

What's the difference between these 2 twinax cables besides the obvious price?

SFP-10G-AOC10M           $260

SFP-H10GB-ACU10M      $410

Both are active cables and 10 meters.

The compatibility document does show some switches accept both, others one one of the two.
