HDMI over Fiber Extender - HDMI ExtensionHDMI Cables Length Limits, DVI Cable Distance LimitationsHDMI Cables Length LimitsThere's no official length limit for HDMI cables, but 6 meters (about 20 feet) seems to be the accepted limit on common HDMI cables. Although the HDMI spec gives no length limit explicitly, the requirements of the spec implicitly give rise to some length limitations for "compliant" cables. A cable isn't permitted to degrade the signal past a certain point. An HDMI cable is
deemed spec compliant if it meets either one of two tests: an "eye-pattern" test which measures the overall shape of the HDMI waveform at the cable end, or a set of parametric tests which measure the attenuation and other losses in the signal. As a result, the maximum cable length is very much dependent cable design. Some of the longest HDMI cables, certified compliant by official HDMI Authorized Testing Centers go as far as 40 feet. For really long cable runs, extender devices transmit HDMI or component-video over Cat-5 or fiber-optic cable. Some of the best-price-high-quality HDMI extenders come from Lindy. Fiber Optic HDMI over Fiber Extender, 300m (Full HD 1080p)The Fiber Optic HDMI Extender is the most cost effective, high performance solution on the market for sending HDMI signals over incredible distances.

More on distance limitations & DVI Cable Distance Limitations With standard DVI cables you can extend the distance for digital monitors, with fixed cables and connections, by up to 7.5m. For distances greater than 7.5m, special low attenuation cables are
recommended to provide satisfactory results. For optimum performance, at distances from 7.5m up to 25m, we recommend you use LINDY Super Long Distance DVI Cables or LINDY Premium Gold Super Long Distance DVI cables. For distances over 25m you can use either a DVI Repeater / Extender solution, or LINDY Fiber Optic DVI Cables. |
