Since the birth of the HDMI standard, the HDMI cable has realized the effective transmission of audio and video signals with its excellent performance. In the continuous change of the HDMI cable transmission carrier, the HDMI high-definition cable with optical fiber as the carrier suddenly became popular. So, are fiber optic HDMI cables better? and is fiber optic HDMI worth it?

It can be seen from the comparison table: Compared with the traditional copper core wire, HDMI fiber optic cable has long-distance lossless transmission, accurate color reproduction, high refresh rate, high audio fidelity, high bandwidth, etc., low power consumption transmission, and strong anti-interference radiation ability. These are why are fibre optic cables better than copper. The advantage, of course, is that the price is relatively higher.

1.Optical fiber HDMI cable volume and lossless transmission
The body of the fiber optic HDMI cable is thinner and softer, which is more suitable for large-area embedding, and has the characteristics of super bending and impact resistance. The outer diameter of the cable is extremely small, which is very suitable for installation and construction in narrow spaces. The HDMI cable is about 60% smaller in volume and weight than the traditional copper cable. The raw material is quartz, which saves metal materials and is conducive to the rational use of resources. The fiber optic HDMI cable is completely free from external electromagnetic interference, and can truly achieve lossless transmission, with ultra-low noise floor and ultra-high signal-to-noise ratio, ensuring the ultimate high-definition audio-visual enjoyment.

2.The optical fiber HDMI cable has the advantage of long-distance transmission
The optical fiber cable has its own photoelectric module chip, and uses optical signal transmission. The attenuation of long-distance signal transmission is basically negligible, ensuring 8K video and high-fidelity audio transmission. The medium distance is far longer than the traditional copper core wire, and the longest transmission distance can reach 300m. by. The traditional HDMI cable generally does not have a standard chip, and the signal loss is relatively high.
For traditional copper cables, the limit transmission distance is generally 35 meters. Signals are easily distorted during long-distance transmission over 20 meters. Repeaters are required to achieve long-distance transmission. For HIFI, projector, and video surveillance systems, the long-distance transmission signals of traditional copper cables are easily distorted, and repeaters must be added. When arranging these devices with optical HDMI cables, there is no need to worry about the attenuation or distortion of the transmission signal, and the system equipment can be arranged according to the actual needs.


3.Free from external electromagnetic interference
The traditional HDMI cable, which transmits electrical signals through copper wires, is vulnerable to external electromagnetic interference, video frames are easily lost, and the audio signal-to-noise ratio is poor. The optical fiber HDMI cable transmits optical signals by optical fiber, without external electromagnetic interference, and can achieve lossless transmission, which is very suitable for game e-sports players and high-demand industry professionals.


4.48Gbps ultra-high-speed bandwidth
The full length supports 7680*4320 resolution, 48Gbps high bandwidth, 120Hz high refresh rate, and complies with the HDMI2.1 protocol standard, while the traditional HDMI copper-lamella cable is subject to signal attenuation, which is difficult to meet. The HDMI fiber optic cable uses optical fiber transmission, which has a wider frequency band and a larger communication capacity. For gamers, there is no need to worry about the problem of transmission bandwidth at all, and can enjoy multi-level smooth and colorful game screen.

Because the optical fiber HDMI cable uses optical fiber medium transmission, it is not affected by external radiation, and the signal transmission is stable. The traditional HDMI cable is easily affected by radiation because of the use of metal cables.

From the above points, we can roughly see the important advantages of optical HDMI cables. In fact, the optical fiber HDMI cable has many advantages that the copper core HDMI cable cannot match, such as: strong corrosion resistance, strong radiation resistance, good windability, no sparks, small leakage, strong confidentiality, etc. Use in special environments or military.
