celexon UHD Optical Fibre HDMI 8K 48Gbps Active Cable 15m, black

The celexon UHD Optical Fibre HDMI Cable is HDMI 2.1-compliant and transmits signals at up to 48 Gbps with resolutions up to 8K (7680x4320p @60Hz with up to 12-bit colour depth) and 4K (4096x2160p @120Hz with up to 12-bit colour depth). The hybrid fibre optic cable with 4 optical fibres and 8 copper conductors enables interference-free transmission of high data rates even over very long distances. To achieve this, the electrical signal is converted into light pulses in the "Source" connector, which are transmitted via the optical fibres to the "Display" connector, where they are converted back into an electrical signal. It is therefore important to observe the installation direction of the cable.

celexon's cable is very thin with a diameter of 5.5 mm. With a bending radius of max. 30 mm and 10 loops over the entire cable, it offers very high flexibility during installation. The very thin and narrow connector allows the cable to be plugged in even in hard-to-reach places. In addition, no adjacent ports are blocked when this connector is plugged in.

With the new dynamic HDR (High Dynamic Range) methods such as Dolby Vision and HDR10+, not only can a greater dynamic and colour range be displayed, making the image brighter and more detailed, but image optimisation is also individually adapted to each image, so that rapid colour changes between high contrasts (e.g. image transitions from white to black) are rendered more naturally.*

The Enhanced Audio Return Channel (eARC) is the new generation of ARC and is included in the HDMI 2.1 specification. This extension allows up to 32 audio channels with uncompressed 24-bit/192kHz data streams at up to 38 Mbps to be transmitted. This enormous increase in bandwidth and speed enables all audio formats such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X to be transmitted without compression.*

Another feature of this cable is the Automatic Low Latency Mode (ALLM), which will be of particular interest to gamers. This reduces delays by removing advanced video processing, thus offering the fastest possible display response. The prerequisite here, in addition to an ALLM-capable television, is that the source devices deliver a high-quality video signal that can be immediately reproduced by the display. This means that no perceptible delay should be noticeable between pressing a button on the controller and the response time on screen. This enables an even more direct and precise gaming experience. All connected ALLM-capable devices automatically switch to the appropriate mode with the shortest possible latency via handshake. Even with an intermediate AV receiver, no additional settings need to be made.*

Variable Refresh Rate (VRR) is another feature brought by the HDMI 2.1 specification. Here, the refresh rate of the source device and the output device are synchronised to avoid judder and tearing in the image. The refresh rate can move freely in the range between 30Hz and 144Hz and adapt optimally to reproduce interference-free and as sharp images as possible. Without VRR, for example in video games, parts of the image can overlap and several sub-areas of the image can build up successively (screen tearing). The only alternative to avoid these artefacts without VRR would be to throttle the frame rate entirely or to set a lower resolution, which would greatly impair the quality of the image.*

The additional Ethernet channel enables internet-capable AV components to be connected to the home network using only an HDMI cable. It is therefore sufficient for the television to be connected to the network via cable. The AV receiver or Blu-ray player then receives the network signal passed through via the HDMI cable, in addition to the actual video signal. This means a network switch and additional cables can be dispensed with.*

All celexon UHD HDMI fibre optic cables are individually tested for functionality using high-quality measuring instruments. Special attention is paid to the EBR (Error Bit Rate) and only cables with maximum data transmission are released for sale.
