Accessories supplier DVIGear introduced a line of copper cables designed to transport DisplayPort signals with bit rates up to 21.6 Gbps over cable lengths of up to 15 meters and support uncompressed DisplayPort resolutions up to 4096 x 2160 at 60 Hz, the company said Thursday (http://bit.ly/1rFpN0s). Long-distance transport of High Resolution DisplayPort signals over copper cables “must overcome several challenges, such as insertion loss, differential skew and jitter,” the company said. Conventional cables that support lower resolutions at short distances are often unable to support the data rates required by higher resolutions at longer distances, it said. “The resulting video can be disrupted by visual artifacts or may not be visible at all.” To overcome these challenges, DVIGear built its DisplayPort cables with heavy-gauge copper wire, “which allows high speed signals to pass with minimal jitter” and devoid of other artifacts, the company said.
