What is active fiber optic hdmi cable?

Fiber optic HDMI cable is a kind of HDMI cable that uses optical fiber as the transmission medium to make HDMI signal transmission cable, and integrates its photoelectric conversion cable at the interface. Also known as active optical cable (HDMI AOC Cable).

How does fiber optic HDMI cable work?

The principle of fiber optic HDMI cable is to integrate the photoelectric conversion cable at the HDMI interface and use optical fiber as the transmission medium material; in the process of transmission, the HDMI fiber optic cable transmitter converts the HDMI signal into an optical signal, and transmits it to the HDMI fiber through the optical fiber medium The receiving end converts the optical signal into a lossless HDMI signal and outputs it to the display device.

Fiber optic HDMI cable composition

Fiber optic HDMI cable is mainly composed of three parts: Source, Fiber optic cable, Display

     Source: Convert the hdmi signal into an optical signal and output it to the fiber optic cable

     Fiber optic cable: connect the transmitting end to the receiving end, responsible for the stable transmission of optical signals

     Display: Convert the optical signal sent by the transmitter into an hdmi signal and output it to the display device

The development history of HDMI

In 2002, the earliest HDMI version HDMI1.0 was launched, with a maximum bandwidth of 4.95Gbps, and video support for DVD, Blu-ray, Rec. 709 color gamut, audio supports 8-channel PCM, 24bit/192kHz audio source, which means that it can already support 1080p full HD resolution and 7.1 sound system.

In 2004, HDMI1.1 version added support for DVD-Audio. In 2005, HDMI 1.2 version added DSD lossless format to the support list.

In 2006, HDMI 1.3 version increased the bandwidth to 10.2Gbps, supported xvYCC wide color gamut, and unlocked new audio technologies such as Dolby TrueHD and DTS-HDMA in audio. After that, minor changes such as 1.3a, 1.3b, 1.3b1, and 1.3c were successively launched; in the same year, when the SamsungBD-P1000, the world’s first Blu-ray player, was launched, it was already equipped with an HDMI interface.

In 2009, the first HDMI version HDMI1.4 that supports 4K30p and 3D came out, and added 100Mbps network transmission function

In 2013, HDMI2.0 increased the bandwidth from 10.2Gbps to 18Gbps, supports 4K60p and is compatible with Rec. 2020 color depth. In terms of audio, 32-channel audio sources are supported.

In 2015, HDMI2.0a added support for HDR, and HDMI2.0b added support for another high dynamic range technology, HLG.

In 2017, HDMI2.1 increased the bandwidth to 48Gbps in one go, supports 8K/60Hz, 4K/120Hz format video, 16bit color depth, and can transmit dynamic HDR data, which is Dolby Vision.

Fiber Optic HDMI Cable vs HDMI

What are the advantages of fiber optic HDMI cable?

1.Optical HDMI cable volume and audio and video transmission advantages

As people’s requirements for audio and video transmission quality are getting higher and higher, there is a more urgent need for ultra-high-speed and ultra-long-distance optical transmission systems. Compared with copper core HDMI, HDMI optical fiber signal transmission is different in that HDMI optical fiber has ultra-fine wire diameter and light weight, which is reduced by up to 60% year-on-year, saving metal materials and facilitating the rational use of resources. HDMI fiber optic cable is not subject to external electromagnetic interference, and can truly achieve lossless transmission to ensure high fidelity of the signal, especially for audio and video information that requires extremely high transmission materials, HDMI fiber optic cable has ultra-low noise floor and ultra-high signal-to-noise ratio, to ensure the ultimate purity of the sound.

2.100 meters of lossless transmission, Fiber optic HDMI cable has the advantage of length

Because the fiber optic HDMI cable adopts the optical fiber transmission medium, the long-distance signal transmission attenuation is basically negligible, the relay distance is long, and the longest transmission distance can reach more than 300m. For HIFI, projector, and video surveillance systems, the long-distance transmission signals of traditional copper cables are easily distorted, and repeaters must be added, which directly leads to the unavailability of the equipment or a worse experience. And HDMI fiber optic cables do not need to worry about the attenuation or distortion of the transmission signal when arranging these devices, and the system equipment can be arranged according to the actual needs of users.

3.Fiber optic HDMI cable has ultra-high-speed bandwidth of 18Gbps or even 48Gbps

The current PUBG, League of Legends, Battlefield, Need for Speed, Grand Theft Auto and other games all require high refresh rates and immersive audio-visual effects, which require very high video transmission bandwidth, and current 2K/4K/8K display devices are becoming more and more gamers The first choice, to ensure 2K@60Hz, 4K@60Hz, 4K@120Hz, 8K@120Hz lossless transmission requires HDMI optical cable to achieve. The traditional HDMI copper cable is subject to signal attenuation, and it is difficult to meet the high-bandwidth transmission requirements of 18Gbps or even 48Gbps. The advantages of HDMI fiber optic cables are that the transmission frequency bandwidth is large, the communication capacity is large, and the insulation and anti-electromagnetic interference performance is strong, which just allows you to accurately experience such a strong shocking effect in 3D, 4K/8K games without worrying about transmission. Bandwidth problem, enjoy the multi-level smooth and colorful game screen.

4.Optical HDMI cables are immune to external electromagnetic interference

The optical fiber HDMI cable transmits optical signals and is free from external electromagnetic interference. It can achieve true lossless transmission and ensure the high fidelity of transmission, especially for audio that requires high transmission materials. Connect the optical fiber HDMI cable to cinema-level audio-visual effects immediately.

We have to believe that in the future, optical HDMI cable will become a necessary wire for high-definition transmission. The traditional HDMI high-definition cable is subject to signal attenuation, and it is difficult to meet the high-bandwidth transmission requirements of 18Gbps or even 48Gbps. The optical HDMI cable does not need to worry about the transmission bandwidth problem at all, you can enjoy the sound quality effect and colorful high-definition picture.
