One hundred meters lossless transmission open Bor fiber HDMI cable dismantling evaluation

Evaluation Preface

On April 10th, Borel launched a heavy 100-meter optical fiber HDMI cable, which made up for the long-distance signal transmission problems in the high-definition industry and brought a "gorgeous" solution to HDTV signal transmission for home theater wiring and engineering. Has been focusing on the open industry of the HD industry, the launch of fiber HDMI cable, with its "long, light, soft" features to solve the traditional copper core HDMI cable transmission distance is short, large volume and weight is not easy to bend the pain point of the industry, and fiber optic HDMI The biggest bright spot lies in the complete isolation of electromagnetic interference. It has achieved strong anti-interference performance by means of photoelectric isolation, and even without interference, it can output authentic pictures over long distances, and is therefore widely enjoyed by enthusiasts.

So what kind of experience will be brought to us by the recently launched Kebor fiber HDMI cable? Next, we will evaluate the 25-meter optical HDMI cable from Bor, and look through the details from the appearance to the dismantling and then the actual experience.

Out of the box appearance

Do not know if you have home wiring, because the HDMI high-definition line distance and the limitations can not be bent and can not play better? Believe it or not, anyway, Xiao Bian in the home theater decoration, especially to solve the connection problem when lifting the telephoto projector and the source, there is a distance of about 15 meters between the output and the input, in the traditional copper core HDMI HD line selection There are many limitations. In addition to the foreign brands such as the German Snake and the Japanese Akihabara, the long-distance transmission of other traditional copper core HDMI cables will more or less bring about the phenomenon of instability such as screen splash and color distortion. It is possible to "smoothly" transmit signals, but in order to obtain better interference immunity, the cables have to be made "tougher than the thighs", allowing the cables to be sacrificed for lightness, flexibility, and the like.

As we all know, data transmission is affected by the transmission medium is very large, the traditional copper core media transmission distance limit is 35 meters, in addition to data transmission, copper core media data transmission with the distance becomes longer, the screen response speed has decline. The transmission principle used by the optical fiber core is total reflection of light. The transmission speed of the signal at the optical fiber core is close to the speed of light (300,000 km/s). Therefore, there is almost no delay in the response speed. There are "fiber HDMI cable" and "fiber optical 100 megabyte network". In the same way, everyone can comprehend the same thing. Kaibol Fiber Optic HDMI cable provides 25 meters/40 meters/60 meters/70 meters and 100 meters to players with different needs. It is suitable for digital set-top boxes, computers, game consoles, DVDs and other devices with HDMI signal output interface and HD projectors. High-definition, high-definition video and audio signal transmission between high-definition digital televisions and monitors is used in a number of engineering applications, such as audio and video entertainment systems, high-definition video conferencing office systems, multimedia education systems, public security high-definition monitoring systems, broadcast television control systems, large-scale Medical imaging systems are also widely used.

In addition, the optical fiber core diameter is only 50 micrometers and its diameter is only 1/2 of that of the hair, so it can be made light and soft. Compared with the copper wire, it can reduce the volume and weight by 60%. It is “long, light and soft”. This is synonymous with fiber optic HDMI, so there are more advantages when wiring through.

The Kaibol Fiber HDMI Cable for this test is a 2.5-meter version 2.0. It is tightly wrapped with a four-ring tie and is not easily knotted. The 19-pin plug has a protective plastic sleeve to prevent abrasion and scratches. It is reported that the product is 40 meters or more in length. It will be rolled up with cable trays, and it will be easier to manage the line, which shows that Kaibor’s sincerity is full.

Kaibol fiber HDMI cable allows the tensile force of 100N/200N, allowing the compression force of 200N/400N, which means that according to daily use, it will not cause damage to the optical fiber HDMI cable. It is worth noting that a certain amount must be reserved at the joint. The distance (official advice 15cm) can be bent to prevent the joint between the plug and the optical fiber core from being broken. The minimum bending radius (dynamic/static) is 80mm/40mm. Due to the special characteristics of the optical fiber material, everybody in the process of using Can not be folded.

Open Bor fiber HDMI cable plug shell using zinc alloy material, pressure, not easy to break, coffee gold color with a strong sense of light, compared to plastic material shell after a long time use will occur embrittlement phenomenon, zinc alloy joints not only look good and durable Durable, 24K gold-plated process at the joints, access equipment more secure. Kaiboer fiber HDMI cable through the laser carving small lead logo Source and large lead logo Display, to remind users to connect the signal source and display, design humanity, in addition to laser engraving open Bor LOGO, generous decent.

Since it is said that "long, light, and soft" is the advantage of the KBL fiber HDMI cable, the "long" has been mentioned above, and the next two intuitive features are "light" and "soft"!

Compared with ordinary copper core HDMI, the advantage of wire thickness is very obvious, and it is conducive to pipe wiring. At the same time, thanks to the soft characteristics of the fiber core, Kaibra fiber HDMI cable can realize the bending action of the copper core HDMI cable, so it will be on the wiring. Bring a lot of convenience.

Comments: In terms of appearance, Kaibul Fiber HDMI cable material is solid, the joints use zinc alloy high-end technology and high-definition equipment, metal wind more ride, practical, thanks to the physical properties of fiber core material, "long, light, Soft "more conducive to wear pipe wiring, open Bor fiber optic HDMI cable changed the signal connection of the HD line, more flexibility.

Dismantling

With the wide application of 4K2K audio and video, especially UHDTV, the transmission performance of data transmission on the transmission interface is becoming higher and higher. Under the transmission connection requirements of more than 100 meters, the existing copper core HDMI line is bound to be unable to use normally, and the copper core HDMI is When high-speed signals are transmitted with electromagnetic interference, the HDMI 2.0 transmission bandwidth standard is 18 Gbps. Therefore, there is a need for a substantial upgrade of HDMI lines. Open Bor fiber optic HDMI cable integrates transmission interface with AOC fiber optic cable technology and transmits it with optical fiber to transmit signal characteristics with optical fiber. It can easily meet the demand and exceed the limit of 100 meters. It also benefits from the physical characteristics of the optical fiber core and will interfere with electrical specifications. Through the "electro-optical conversion - optical fiber - photoelectric conversion" to achieve 0 interference transmission. The Kaibol fiber HDMI line uses AOC (active) cable solutions, a system consisting of two optical transceivers and a jumper. This system is faster and more reliable than a stand-alone device. Better, the following is the circuit design at the interface:

When electrical signals are converted into optical signals, high-speed transmission through optical fibers enables electromagnetic interference/electromagnetic radiation and other problems to be achieved, and the transmission distance is far away. From the opened cables, we can see that the open Bor optical fiber HDMI cable strictly follows Project wire gauge standards, the outer layer of TPU outer sheath, the second layer is aramid filled, the third layer of the filler rope and stranded tinned copper wire outer sheath (the inner layer of twisted tinned copper wire) in accordance with In a certain order, the innermost layer is a sub-cable sheath (tight-jacketed fiber with blue, orange, green, and brown 4 cores). The multi-layer protection is covered in a wire diameter of only 4 mm. The manufacturing process can be seen.

Finally we take a look at what the fiber looks like:

Comments: From the joint structure and cable structure is enough to witness the professional degree of Kaibol in the development of optical fiber HDMI cable, four layers of stack material and optical fiber core can see the solid material, strict engineering line gauge also ensures that AOC fiber HDMI cable can provide us with Lossless transmission of signals, what kind of experience will there be in the actual experience?

Play test

Regardless of the picture quality experience, Kaibor Fiber HDMI cable has a good experience. The socket size is designed to be accurate, and it is not easy to fall off when plugged into the device. Thanks to the flexibility of fiber HDMI, the corners and narrow spaces in some corners also change. It is more "handy".

Below, we experienced the video experience brought by this Kaibuli 25m fiber HDMI cable through an intuitive experience. For 4K resolution video output, it perfectly showed the advantages of large resolution video, and the sharpness control of the picture was very good without noise. , No Moire, details can stand the test of magnification (due to digital shooting and multiple transcoding, the following pictures can not represent the real situation, for reference only).

The open BOR fiber HDMI cable is version 2.0, data transmission bandwidth is 18Gbps, can transmit high-definition ultra-high-definition Blu-ray high-quality audio and video over fiber optic cable transmission, especially high-contrast, high-frame-rate video such as 4K HDR, 4K@60 FPS, etc. The picture, under the transmission of the fiber core, the picture has no interference, is more pure and transparent, and the picture responds more quickly. In the picture below, the depth of the night sky and near-field trees in the distance between the juveniles and the HDR version have a significant effect, and they are clearly distinguished from the formation of nearby ships. Leaves and weeping branches are clearly outlined in the night sky, and the overall picture shows more dark fields. The details, but when playing a video of a football game, driven by the 25-meter HDMI cable, there will be no smearing during running and passing, and the silhouette of the character is clearly visible.

In order to have a more intuitive experience of the audio and video experience brought by the Kaibuli 25-meter fiber HDMI cable, we chose several sets of scenes and a 3-meter coiled copper core HDMI cable to compare the effect of the AB screen shot.

Personally speaking, the two are similar in terms of picture output sharpness and detail expression, and the color saturation is also the same, but careful observation can be seen in the use of copper core HDMI cable connection, in the show some colorful Occasionally, moire appears on the screen. It is worth mentioning that everyone should be aware of the two screens that have almost the same effect. The Kaibol fiber HDMI cable is 25 meters, while the traditional copper core HDMI cable is 3 meters.

Comments: Kaibol fiber HDMI cable version 2.0 supports ultra-high definition Blu-ray standard, especially the now popular 4K, HDR and 60FPS high frame rate video popular, Kaiboer fiber HDMI cable carries an important role in home audio and video entertainment, on the quality of Bor optical fiber The HDMI line output quality is excellent; on the process, up to 100 meters of effective transmission distance plus interference-free features, can definitely kill the same distance of most of the HDMI line (you know, the traditional HDMI line even with the signal amplifier only Can achieve a length of 35 meters and can only transmit 1080P resolution). For the emergence of new standards such as the 8K in the future, the traditional HDMI cable may not be able to meet the future demand. This is probably the real "killer" of the optical HDMI cable based on the present and the future. But unfortunately, the current price of fiber optic HDMI cable is not close to the people.

General evaluation evaluation

With the improvement of the disposable economic level of the people, home audio-visual entertainment has become increasingly widespread, smart boutiques have driven consumption upgrades, and Kai Bor, who has always been a force player for 4K hard disk drives, has launched a 100-meter fiber HDMI line to the industry. Perhaps this is because Under the blessing of the ultra-high-definition Blu-ray standard, traditional copper core HDMI can play a smaller space. It can be seen that manufacturers have already seen the broad market prospects of optical fiber applications in the HDMI high-definition line.

Kaibol's 100-meter optical fiber HDMI cable adheres to the three characteristics of “long, light, and soft” in appearance, and adopts a strong light-sensitive zinc alloy material at the plug. It is quite open to Bor's own design language, working from the inside and rigorous engineering. The wire gauge can be seen that the product will have a more durable service life. Thanks to the interference of the optical fiber core, the Kaibuler 100-meter optical fiber HDMI cable has the same picture quality output as the high-end copper core HDMI cable, and is even better than blue and blue. Blue, and as its outstanding highlights and features, it is easy to break through the bottleneck of 100 meters. Therefore, Kaibra Fiber HDMI cable is used more widely. Of course, the open material fiber HDMI cable with a very high quality of material, technology and sound and picture quality also has a slightly higher price. In a word, if you are someone who has an attitude towards picture quality, especially when using projectors and other long-distance transmission. The scene, Kaibol hundred meters of fiber optic HDMI cable is still very worthwhile to start.
