HDMI (High Definition Multimedia Digital Transmission Interface) is developed on the basis of DVI (Digital Visual Interface). Starting from HDMI1.0, the HDMI standard has developed to 1.1, 1.2, 1.3, 1.4, 2.0, 2.1, 2.1 a. HDMI cables are usually used to connect audio-visual equipment to TVs and monitors, so most of them are transmitted over short distances, usually only 3 meters long; what should users do if they need more than 3 meters? If you continue to use copper wire, the diameter of the copper wire will become larger, it will be difficult to bend, and the cost will be high.

 

Therefore, the best way is to use optical fibers. The solution currently on the market for transmitting HDM ultra-clear signals over long distances is to use optical fibers to transmit high-speed signals. Copper wires are still used for low-speed signals, because there are technical challenges in converting low-speed signals into optical fibers. Therefore, this high-speed signal uses optical fiber, and low-speed signal and power supply use copper wire, which is called Optical copper hybrid fiber.

 

Although the Optical copper hybrid fiber has brought the lossless transmission of long-distance signals to a very high level, there is still a technology that completely solves the existence of copper wire as a transmission conductor, that is, the pure optical fiber HDMI2.1 cable. This article will introduce the difference between pure fiber HDMI2.1 line and optical copper hybrid line fiber HDMI2.1.

Pure optical fiber HDMI 2.1 has no copper wire as signal transmission conductor

Although the Optical copper hybrid fiber uses optical fiber to replace part of the copper wire, it breaks through the limitation of the original HDMI short-distance transmission, but there is still a part of the copper wire in the hybrid cable as the transmission of low-speed signals. If it is in a strong magnetic field environment, it may be interfered by electromagnetic radiation, making signal transmission unstable. The pure optical fiber HDMI2.1cable MPO developed by HeyOptics uses only optical fibers for transmission without any copper wires. Optical fiber transmission is free from electromagnetic interference, can transmit stably in such environments, and can solve the problem of electromagnetic interference.

Pure optical fiber HDMI2.1 is free from external electromagnetic interference and is thinner and softer

HeyOptics Pure optical fiber HDMI 2.1 cable MPO fully complies with the HDMI2.1 standard. The signal transmission adopts optical fiber without copper wire, and the optical fiber transmission is free from electromagnetic interference. The transmission signal is uncompressed, and the maximum bandwidth is 48Gbps, which can perfectly transmit 8K ultra-high-definition images, and the longest transmission distance can reach 303m. Compared with the traditional copper wire, this fiber optic cable is longer, softer (only 3mm in diameter), lighter, has better signal quality and perfect electromagnetic compatibility.

Pure optical fiber HDMI2.1 adopts MPO head, which is detachable and upgradeable and easy to wear, regardless of direction

At the same time, HeyOptics pure optical fiber HDMI2.1 line adopts MPO head for split design, which is not inconvenient for users who have pre-installed in the project. At the same time, due to the compact MPO head design, the space required for pre-embedded through-pipe wiring is smaller, and there is no need for a larger space for wiring like the optical copper hybrid line. In addition, the split MPO head used by HeyOptics is the separation of the module and the main fiber, which can realize any exchange of the modules at both ends. For example, pure optical fiber HDMI2.1 can be changed to pure optical fiber DP1.4, pure optical fiber DVI, pure optical fiber HDMI conversion DVI, etc.

Pure optical fiber HDMI2.1 supports subsequent product version upgrades

HerOptics pure fiber HDMI2.1 adopts six-core 10 Gigabit fiber, and the main optical cable supports 100Gbps or higher transmission bandwidth, which can facilitate future product version upgrades: that is, no need to change cables. It completely solves the disadvantage that the integrated cable cannot be updated and upgraded, allowing users to wire it once, and can easily upgrade the system equipment in the process of up to 10 years, keeping pace with the times.

Conclusion

The pure optical fiber HDMI 2.1 MPO cable has no electromagnetic interference and no delay, and is not afraid of harsh application environments. Pure optical signal transmission solves the electromagnetic interference and signal loss caused by the transmission of high-frequency signals by metal conductors in the past. For all kinds of harsh electromagnetic control environments, the performance is amazing, and it deserves to match the appropriate product.
