celexon UHD Optical Fibre HDMI 8K 48Gbps Active Cable 25m, 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. For this purpose, the electrical signal at the "Source" connector is converted into light pulses, 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 slim 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 also allows the cable to be plugged in at hard-to-reach locations. In addition, no nearby ports are blocked when this connector is inserted.

With the help of the new dynamic HDR (High Dynamic Range) methods such as Dolby Vision and HDR10+, not only can a greater dynamic range and colour gamut be displayed, making the image more brilliant and detailed, but the image optimisation is also adapted more individually to each image, so that rapid colour changes between large 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 enhancement 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 for this, 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 ensures that no noticeable delay is perceptible between pressing a button on the controller and the response time in the image, enabling an even more direct and precise gaming experience. All connected ALLM-capable devices automatically switch via handshake to the appropriate mode with the shortest possible latency. Even with an interposed AV receiver, no additional settings are required.*

Variable Refresh Rate (VRR) is another feature that comes with the HDMI 2.1 specification. Here, the refresh rate of the source device and the output device is 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 as possible images. Without VRR, for example in video games, parts of the image may overlap and several sections of the image may build up one after another (screen tearing). An alternative to avoiding these artefacts without VRR would be to throttle the frame rate entirely or set a lower resolution, which would significantly reduce 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 by cable. The AV receiver or Blu-ray player then receives the network signal passed through alongside the actual video signal via the HDMI cable, eliminating 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 equipment. Special attention is paid to the EBR (Error Bit Rate) and only cables with maximum data transmission are released for sale.
