celexon UHD Optical Fibre HDMI 8K 48Gbps Active Cable 50m, 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 glass 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 glass 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 nearby ports are covered when this connector is plugged in.

With the help of 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 more brilliant and detailed, but the image optimisation is also adapted individually to each image, so that rapid colour changes between large contrasts (e.g. image change from white to black) are displayed 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 allows 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 the ALLM-capable television, is that the source devices deliver a high-quality video signal that can be immediately reproduced by the display. There should be no noticeable delay 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 latencies via handshake. No additional settings are required even when an AV receiver is connected in between.*

Variable Refresh Rate (VRR) is another feature introduced by the HDMI 2.1 specification. Here, the refresh rate of the source device and output device are synchronised to avoid juddering and tearing in the image. The refresh rate can move freely between 30Hz and 144Hz and adapt optimally to deliver smooth and as sharp as possible images. Without VRR, it can happen with video games, for example, that parts of the image overlap and several sections of the image build up one after another (screen tearing). An alternative to avoid these artefacts without VRR would be to completely reduce the frame rate or set a lower resolution, which would severely compromise image quality.*

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, in addition to the actual video signal, the network signal passed through via the HDMI cable. This eliminates the need for a network switch and additional cables.*

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.
