In what kind of situation do you need an optical cable with HDMI? If you need to transmit 3D video, 4K/8K HD video, or want to ensure the purity of audio sound, the distance is more than 10 meters, HDMI optical cable is definitely worth considering.

With the advent of the 5G+8K era, displays have evolved from 4K to 8K, and multimedia conference rooms and home theaters have increasingly high requirements for long-distance video and audio transmission.

2017 has seen the advent of 4K+HDR/Dolby Vision with WCG video and native 24/96K Hi-Res Audio tracks, which have long surpassed the data transmission bandwidth requirements needed for 1080P and even 4 K in the past. Today’s data-rich content has increased dramatically, and these signal transmissions can achieve up to 50% of what they used to with copper core wire.

In recent years, under the active promotion of BONESTEC and many manufacturers, the price of fiber optic HDMI has been repeatedly reduced, so when you are ready to decorate multimedia conference rooms or home theaters and e-sports rooms, fiber optic HDMI is definitely worth considering: 18/48Gbps ultra-high bandwidth, 60/120Hz or even 240Hz refresh speed, transmission speed fiber optic is also many times faster than copper wire.

Also in the AB test, 5m 4K copper core HDMI was compared with 5m 4K optical HDMI cable. It is obvious to the naked eye that fiber optic HDMI cables provide better color depth, brightness and contrast. It is able to reproduce the original signal extremely well.

Copper is very susceptible to electromagnetic interference (EMI). Spurious EMI in the average home is prevalent in all our wireless devices, and copper cables act like antennas to them, making the true signal transmission suffer. This interference is considered noise in the image, which is a grainy effect not present in the original content. In addition, copper HDMI cables cannot do long distance transmission of 4K signals, and while copper HDMI cables can use signal amplifiers to make the cable longer, the use of amplifiers degrades the signal to 1080p or even lower, and can usually only do 30 meters.

Fiber optic HDMI cables have zero resistance because they use light waves on glass fiber to transmit audio and video signals at the speed of light. The result is zero signal loss and a clean, wide real-world eye diagram at all distances. If bandwidth and data speed are more demanding, then fiber optic HDMI cables win out – nothing is faster than the speed of light. Optical fiber is unaffected by electromagnetic interference, so the image is very smooth. Native 4K movies always look great, and the added clarity and resolution enhances the gaming experience.
If you already have a complete 4K video system or need to transmit 3D video, 4K/8K HD video or want to ensure audio sound purity over a distance of more than 10 meters and need the highest, yet inexpensive, signal transmission carrier between the 4K source and the display, BONESTEC fiber optic HDMI cables are worth a try.
