I wonder if it's possible to increase the speeds, without having to revise the chip-on-the-motherboard. Then users could upgrade their speeds by buying a new "faster" cable.
> Our telecom source noted that Intel made an unusual choice in also using active cabling for future optical-based iterations of Thunderbolt. Passive cabling is more common, but active cabling could offer some advantages. For one, active cables could combine fiber optics with electrical cabling for power transmission. Another good reason to use active optical cables, according to our source, "is that your current electrical ports can be forward compatible with future optical cables."
