With the rapid development of technology, there is a growing demand for high-speed audio and video data transmission. The connectors and cables used by our daily public are gradually upgrading. For example, the specification of HDMI has evolved from HDMI 2.0 to HDMI 2.1, and the transmission rate is enhanced from 6.0 Gbps to 8.1Gbps. Moreover, the speed of USB 3.2 Gen 2 also reached 10 Gbps, and it is expected that USB4 will reach 20 Gbps as well, which is the same as Thunderbolt3.

Video Electronics Standard Association; VESA has released the DisplayPort High Bit Rate 3 ( or DisplayPort 1.4 ) early certification program in January 2017. Authorizing Allion to provide DisplayPort 1.4 Certification and testing service; as an ATL for VESA, Allion will introduce the specifications and details of DisplayPort 1.4 Certification and testing service.

DisplayPort 1.4

DisplayPort 1.4 ( or in short DP 1.4 ) would be the latest specification presented from VESA, compared with DP1.2 the new DP1.4 incorporates the Display Stream Compression; DSC function. Hence, with a high compression rate of 3:1, it is able to support a higher resolution and refresh rate under the same bandwidth. Besides DSC, DP 1.4 includes Forward Error Correction, HDR meta transport in this new update. Therefore, allowing for better performance in video output.

In view of high-frequency signal, mechanical properties, electrical properties and environmental factors that change in the performance of cables and connectors, developers need a complete package of professional laboratory tests and certification programs to ensure the products that can meet the quality conditions and can perfectly show the functional characteristics. In this article about validation technique, Allion experts will introduce different specifications of USB and emphasize on certification. It will also concentrate on products with different interfaces such as SAS 4.0, PCIe’s latest specification of OCuLink interface, and fiber optic cable AOC (Active Optical Cable) and will explain each interface’s characteristics. In addition, we will also introduce some equipment and testing content focusing on electrical test, mechanical test, and environmental test.
