Long Cable to Transmit HDMI Signals

HDMI (High-Definition Multimedia Interface) is an interface standard used for audio and visual equipment, such as high-definition television and home theater systems. HDMI cables are wonderful all-in-one cables that provide high-definition video and sound in a single cable. However, because of their composition they are typically only able to carry signals to about 50 feet (about 15 meters) before they need help to travel farther.

If you'd like to transmit the HDMI signal to 30M, 60M or longer distance, it is not so easy because the frequency of the individual sine waves is such high frequency. As frequencies of the signal increase, the quality of the HD signals degrades. So here we'd present you a solution that can significantly improve HDMI transmission: HDMI Extender.

There are many HDMI extenders on the market. Theoretically extenders that are based on dual Cat5/Cat6 cable can extend HD signals to 250 meters (820 ft), while extenders based on optical fiber can extend HD signals to 300 meters (980 ft). As there later one is more expensive than the former one, it is not widely applied to our home theater systems. So "HDMI extender over cat5/6 cable" is highly recommended. However, not all the HDMI extenders can transmit as long distance as you want. Generally most of the HDMI extenders on the market can only transmit signals up to 60 meters. But fortunately there are some extenders over cat5/6 cable that can transmit to 100 meters or longer. The HDMI extender from VVdeals is the one designed for you. By converting the HDMI signal to TCP/IP protocol, this "HDMI extender over cat5/6 cable" can transmit up to 100 meters when the sender and receiver are directly connected. 

With the help of routers or networking switches, this Extender will extend the HDMI signal to a longer distance for you. For example, if you add one more network switch, the transmission distance will be extended to 200 meters. It is also a HDMI splitter that you can connect one sender with several receivers, such as 4 receivers. Then this HDMI extender over cat5/6 cable will work as a 1x4 HDMI splitter. If you hook up to 8 receivers, it will be a 1x8 HDMI splitter. Therefore you would have found that this extender is really very powerful and practical as it can work as a HDMI splitter over cat5/6 cable. Mini In size, it is portable and elegant. It provides you a perfect solution for your home entertainment system and your engineering project.
