Optical HDMI cables – lossless quality over long distances
HDMI has developed over the years into the interface par excellence for televisions, music systems, projectors, receivers, game consoles and screens. However, the classic all-rounder for entertainment devices has a weakness that is not due to the connection, but to the cable itself: the signal strength decreases over long distances.
It looks different optical HDMI cables out of. They transmit images and sound without any loss of quality - even over long distances between the devices. Regardless of whether you are looking for flexible cabling for your event technology or maximum quality in your home cinema, you have come to the right place with our optical HDMI cables.
Optical HDMI cables – this is how it works
While the transmission with conventional HDMI cables takes place in digital form, the electronic signal in fiber optic cables is first converted into a light pulse. For this purpose there are special converters in the plugs. The optical signal is then transmitted via a flexible Core made of individual glass fibers transmitted. At the end, the conversion takes place into a digital signal, which is then received by the end device. Due to their structure, optical HDMI cables are also known as HDMI fiber optic cables or HDMI fiber optic cables.
High-resolution content without any loss of quality
HDMI has quickly established itself as the standard for consumer electronics and the PC, and for good reason. Current versions enable one high bandwidth and are therefore suitable for Display of high-resolution content . However, the quality decreases as the distance between the source and target device increases. In some cases, this can even lead to image errors or a complete image failure.
Acknowledge this weakness optical HDMI cables out of. The light pulses move at extremely high speeds and cover long distances in a short time. This results in one minimal susceptibility to electronic interference and lossless transmission of high-resolution video and audio signals Distances of up to 100 m . There is also no loss of quality during signal conversion. If you long for impressive picture quality and crystal-clear sound, that's it optical HDMI cables the best choice.
Optical HDMI cables – for event technology and home cinema
Due to its properties, this has... optical HDMI cables but mainly established at events . Quality is the top priority here, but the image and sound signals often have to overcome large distances. This is not a problem for fiber optic cables. They transmit the signals reliably at maximum speed.
Also advantageous: Optical cables do not require complex shielding, which results in smaller cable thicknesses. This makes them extremely flexible and light – ideal for transport and use at events. At the same time, the cables have to be able to withstand a lot. This is ensured by our stable Kevlar coating and the robust metal housing of the plugs. We offer high-quality solutions especially for this application Length of 30 m, 50 m or 100 m at.
Optical transmission technology is suitable for all devices that also use conventional HDMI cables. These include televisions, projectors, receivers, Blu-ray players, game consoles, notebooks and monitors. The area of application is correspondingly broad . Optical HDMI cables are suitable for professional use, for example in conference rooms and offices, and they are also very popular in private use. The reasons for this are always the same: maximum quality, minimal susceptibility to failure and easy installation.
Optical HDMI cables – HDMI 2.0 or 2.1?
Over the years, the transmission standard continues to evolve, resulting in higher bandwidth and a larger range of functions. When purchasing optical HDMI cables, you are faced with a choice: HDMI 2.1 or HDMI 2.0 ? Which version suits you best depends on your requirements.
HDMI 2.1 is the latest generation. With a data rate of 48 Gbit/s, it transmits video content in 8K at 60 Hz or in 4K at 120 Hz. The most important features include Dynamic HDR, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM) and eARC. This means that HDMI 2.1 enables the best possible image and audio quality – provided the connected devices are equipped with the new functions.
The predecessor HDMI 2.0 but it is far from obsolete. This variant is already sufficient for displaying in 4K or playing back lower resolutions at high refresh rates. Also High Speed Ethernet is supported by HDMI 2.0.
A notice: HDMI is backwards compatible with previous versions. This means you can use current cables to connect older devices.
FAQ
What do I have to consider when laying optical cables?
Although optical HDMI cables are known for their flexibility, care should be taken when routing them. If you fall below the specified bending radii, the glass fiber core can be damaged. A kink will impair the quality or no picture will be transmitted at all. It is also best to only loosely roll up the cables during transport.
Are HDMI optical cables bidirectional?
Unlike the conventional variant, the optical HDMI cable is not bidirectional. Instead, it has an entrance and an exit. When wiring the devices, you must therefore pay attention to the direction.
Which optical HDMI cable for 4K?
If you want to transmit 4K content with an optical signal, you will need to use a cable with the HDMI 2.0 specification or newer. The standard has enough bandwidth for 4K at 60 Hz.
Which optical HDMI cable for 8K?
The current standard, HDMI 2.1, allows the transmission of video content in 8K at a refresh rate of 60 Hz and 4K at 120 Hz for the first time. This also applies to optical HDMI cables.
