Wireworld Cable Technology, one of the world's most respected brands of high performance audio and video cables, announces the release of the new Sphere HDMI cable. Wireworld Sphere HDMI cables use an advanced cable design and newly developed active circuit to provide superior video and sound reproduction. Their new Uni-Path cable design improves performance with improved shielding that reduces crosstalk and attenuation. All lengths pass the strict DPL HDMI2.0 testing, with the lengths of 9m to 30m utilizing Wireworld’s HD-Bridge™ active technology. Sphere HDMI cables provide superior system compatibility and support all HDMI2.0 features, including 4K/60, deep color and HDR. The HD-Bridge module in the active (9m to 30m) Sphere cables is a technical marvel that overcomes limitations of previous active cable solutions. With four discrete 12Gbps channels, the HD-Bridge bandwidth extends beyond 48Gbps. Sphere active cables are compatible with all HDMI revisions from v1.0 to v2.0. The HD-Bridge is powered by an external USB connection at the TV. The module requires less than 0.2A, so it can be powered by standard USB sockets and transformers. To improve resolution, the HD-Bridge module contains three discrete power supplies for digital video, bias voltage and DDC. HD-Bridge also includes exclusive adaptive circuitry and a DDC rise time accelerator to maximize compatibility between components.
