celexon UHD Optical Fibre HDMI 8K 48Gbps Active Cable 25m, Black

The celexon UHD Optical Fibre HDMI cable is HDMI 2.1 compliant and thus 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 wires enables interference-free transmission of high data rates even over very long distances. For this purpose, the electrical signal in the "Source" connector is converted into light pulses, which are transmitted via the optical fibres to the "Display" connector, where they are converted back into an electrical signal. It is therefore important that the installation direction of the cable is correct.

celexon's cable is very thin with a diameter of 5.5 mm. With a bending radius of max. 30 mm and 10 circuits over the entire cable, it offers a very high degree of flexibility during installation. The very thin and narrow connector allows the cable to be plugged in even in places that are difficult to access. In addition, no other nearby ports are covered by plugging in this connector.

With the help of the new dynamic HDR (High Dynamic Range) processes such as Dolby Vision and HDR10+, not only can a greater dynamic and colour range be displayed, making the picture more brilliant and rich in detail, the picture optimisation is adapted more individually to each picture, making even fast colour changes between large contrasts (e.g. picture change from white to black) more natural.*

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 to be transmitted with uncompressed 24-bit/192kHz data streams at up to 38 Mbps. This huge increase in bandwidth and speed means that all audio formats such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X can 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 the advanced video processing and thus offers the fastest possible response of the display.

The prerequisite here, in addition to the ALLM-enabled TV, is that the source devices provide a high-quality video signal that can be played back immediately by the display. Thus, there should be no perceptible delay between the keystroke on the controller and the reaction time in the picture. This enables an even more direct and precise gaming experience. All connected and ALLM-capable devices automatically switch to the appropriate mode with the shortest possible latencies via handshake. Even with an interconnected AV receiver, no additional settings need to be made.*

Variable Refresh Rate (VRR) is another feature that the HDMI 2.1 specification brings with it. Here, the refresh rate of the source device and the output device is synchronised in order to avoid jerkiness and tearing in the picture.

The refresh rate can move freely in the range between 30Hz and 144Hz and adapt optimally in order to reproduce images that are free of interference and as sharp as possible.

Without VRR, parts of the picture can overlap and several parts of the picture build up one after the other (screen tearing), for example in video games. An alternative to avoid these artefacts without VRR would be to reduce the frame rate completely or to set a lower resolution, whereby the quality of the picture would suffer greatly.

The additional Ethernet channel makes it possible to connect Internet-capable AV components to the in-house network only via HDMI cable. It is sufficient if the TV is connected to the network via cable, the AV receiver or Blu-Ray player then receives the network via 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 equipment. Special attention is paid to the EBR (Error Bit Rate) and only cables with maximum data transmission are sold.
