In the past two years, E-sports displays have been the fastest growing display segment. With the continuous upgrading of panel technology by upstream panel manufacturers and the participation of more and more downstream complete machine manufacturers, E-sports displays have become more and more popular, especially high-end 4K 144HZ and above high resolution and high brush displays are becoming more and more affordable, 618 Nearly every special price has made many people put it into shopping carts. However, with the improvement of resolution and refresh rate, the bandwidth requirements for data transmission are getting higher and higher, so HDMI2.1 and DP1.4 interfaces are configured on high resolution and high brush displays. The upgrade of the interface and the improvement of the bandwidth also put forward higher requirements for the transmission cable, especially the long-distance connection. In order to ensure the stability of long-distance big data transmission, the traditional copper cable needs thicker wire, better shielding measures and even active trunking, which have led to a greater increase in the size and hardness of the wire, What follows is the difficulty of cost promotion and routing. Those who have played with HIFI system may have a better understanding of this point. Those high-end HIFI wires are often thick and expensive. In order to solve the above pain points of long-distance transmission, FIBBR is the representative Fibre Optical As the times require, I used 15m long FIBBR HDMI2.0 fiber optic cable as the projection cloth when I was decorating my new house many years ago. Its soft and thin cable body saved me a lot of trouble in wiring, and I was very satisfied with its stability over the years. This time, RIBBR introduced its very mature optical data cable technology into the DP cable. This experience is the 3M version of the FIBBR Real series DP2.1 active optical cable. Now let's have a deep understanding.

Unpacking

The packing box is in the black style we are familiar with, but this time, the surface has been treated with patterns, and the texture is very good.

Compared with the HDMI version, the DP2.1 active fiber cable of the 3M version is the same except for the head. The familiar formula has a familiar taste.

The biggest difference between the optical cable and the copper cable is in the head. The optical cable is active, so the cable has a direction. When we route the cable, we must see the host end and the display end clearly. If it is reversed, it will not be displayed.

And HDMI2.1 wire.

The head of DP2.1 adopts zinc alloy+PC shell. In addition to anti fouling and wear resistance, the most important thing is excellent heat dissipation performance, which is more stable for the source; The connector adopts gold-plated terminal, which is resistant to plugging, oxidation and has better electrical performance. The difference between FIBBR and other DP lines is that there is no anti falling hook.

Thanks to the adoption of the parent company Changfei BendRobust special bending fiber, the DP2.1 fiber line has a body diameter of 4.6mm, which is not only thin and soft, but also has good bending resistance.

Compared with the 2 m version of FIBBR DP2.1 copper wire, it can be seen that the wire body is much thinner, and the advantages brought by optical fiber are quite obvious.

experience

Since there is no anti dropping hook on the connector of FIBBR DP2.1 optical fiber cable, the insertion and removal of the cable should be much smoother. In addition, be sure to see the identifier clearly, and do not reverse the host side and display side.

The advantages of thin and soft thread body are very advantageous when routing and finishing, which is much easier than those thick and hard threads.

According to a resolution bandwidth chart summarized by netizens, when 4K 144HZ 10BIT is used, the required bandwidth reaches 39.1Gbit/s, while the bandwidth of DP1.4 is 25.9Gbit/s. Theoretically, it is not enough. Now it depends on DSC compress Technical support, the perfect realization still depends on DP2.1. Although Laohuang does not do anything, but thanks to Suma's efforts, the display will catch up slowly in the later stage. Now, if you want to buy DP line, you should go directly to DP2.1.

Although VESA released the DP version 2.1 specification for the cable transmission length has been improved, the DP40 data cable can exceed 2 meters, and the DP80 data cable can exceed 1 meter, without affecting the UHBR performance. However, the length of more than 2m still needs shorter distance wire materials, while FIBBR DP2.1 active optical fiber line can easily solve the problem of long-distance transmission.

If your host is far away from the display or the display has a large range of activities and requires a longer cable, you can consider the FIBBR DP2.1 active optical cable. The thin and soft cable body is not only convenient for wiring but also resistant to bending, which can support the wide range movement of the display. Now it is a very good opportunity to take advantage of 618 to accept it.
