DP 2.1 80G

DisplayPort 2.1 DisplayPort cable standard, optimizes the configurations for full size and mini size DisplayPort cable, enhances its robustness, thereby improving connection quality and increasing cable length (DP40 cable exceeding 2 meters long, DP80 cable exceeding 1 meter long) without compromising UHBR performance. The DP40 cable certified by VESA supports UHBR10 link rate (10 Gbps), four channel operation, and provides a maximum throughput of 40Gbps; The DP80 cable certified by VESA supports UHBR20 link rate (20 Gbps), four channel operation, and provides a maximum throughput of 80 Gbps.

USB4, In 2019, USB-IF integrated the Thunderbolt 3 protocol (TBT3) on the basis of USB 3.2 , launched USB4 Gen 2x2 and USB4 Gen 3x2. The difference between the past is that the name USB 3.2 is still retained. USB4 is a doubling of the original USB 3.2 transmission speed, reaching 40Gbps, which is the speed of USB4 Gen 3x2. USB4 supports both USB 3.2 and TBT3 transfers. In short, USB4=USB 3.2+TBT3. USB4, like USB 3.2, also has single channel mode and dual channel mode. The USB4 interface and USB 3.2 interface both support the use of the USB PD fast charging protocol.

USB4 integrates multiple protocols as well as support more devices simultaneously, which involves bandwidth allocation. As shown in the figure below, USB4 can allocate up to 22Gbps of bandwidth for data transmission and at least 18GB of bandwidth for display support. Can connect a display with a resolution of 5120x2880 (5k), a refresh rate of 60Hz, and a color depth of 30bit, leaving 18Gbps of bandwidth for data transmission; You can also connect two videos with a resolution of 4096x2160 (4k), a refresh rate of 60Hz, and a color depth of 30bit, leaving 8Gbps of bandwidth for data transmission.

Overview: SAS (Serial Attached SCSI), also known as Serial Attached SCSI, is a new generation of SCSI technology, like the current popular Serial ATA (SATA) hard drives, uses serial technology to achieve higher transmission speeds and improves internal space by shortening connection lines. For raw wires, mainly distinguished based on electrical performance, divided into 6G and 12G, and SAS4.0 24G. However, the mainstream production process is still basically the same. For SAS high-frequency lines, impedance, attenuation, loop loss, and crosstalk are the most important transmission indicators. The operating frequency of SAS high-frequency lines is generally above 2.5GHz. High frequency and low loss communication cables are generally made of foam-polyethylene or foam-polypropylene as insulation materials. Two insulated core wires and two ground wires enter the wrapping machine, and aluminum foil and adhesive polyester tape are wrapped around the insulated core wires and ground wires, insulation process design and process control, structure, electrical performance requirements, and transmission theory of high-speed transmission lines.
