Tributaries just announced that the UHDT TITAN Passive 10-meter (32-foot, 10-inch) HDMI cable has been certified by both DPL Labs and ISF for 18Gbps performance. 

Why is passive such a big deal? Passive HDMI cables are always preferred over active. In addition to incompatibility issues with other electronics, active cables are directional and will not work if reversed. The active end of the cable must be connected to the display and requires power to supply the on-board electronics; typically, these cables harvest their power from unused TMDS voltages. This method works well as long as the source which drives the 5V line has an adequate output. If the source voltage is too low it will draw down the vital 5-volt line. Passive cables are bi-directional and voltage agnostic, making any long run installation simpler and more stable.

Tributaries claims that the development of the TITAN-10 passive HDMI cable is the result of a new copper formulation that eliminates the “Skin Effect.” TITAN’s high-conductivity copper results in lower losses than with standard oxygen-free copper. This design has provided a method of extending the length of an 18G Passive HDMI cable from a a length of 5 meters to 10 meters.

All the specs are here.
