With the development of 4K technology, more and more people are inclined to build 4K system in order to complete the precise work efficiently. To help integrator finish the 4K wiring more quickly, 4KDVB lunched Duallink DVI extender DDL-20. The maximum transmission distance up to 100m.

In the conventional way of signal transmission, 4K signal must be transmitted by using high speed digital cables and the transmission distance is also limited in a small area. Due to its limitation, presentation effect in the project is far from perfect. 4KDVB is committed to providing all aspects of 4K enabled products with the best-in-class performance. The DDL-20 is specially designed for 4K long distance transmission with high speed. It is divided into the transmitter DDL-20-T and the receiver DDL-20-R and they can be connected via CAT.6 cable. It's very easy to operate.

"It is marvelous that long distance transmission of 4K signal can be achieved only by CAT.6 cable." 4KDVB's technical manager Philip has said, "Twisted pair is very suitable for the engineering wiring because it has many advantages such as light weight, strong anti-jamming performance, low attenuation, low-cost material, etc."

The DDL-20 has the following features:
