Designed for compatible 8K at 60Hz equipment, it combines HDMI 2.1 bandwidth with a fibre-optic signal path for longer AV installations. It suits rooms where a projector, TV or display is positioned well away from the computer, console or media source. The 30m run is intended for layouts where ordinary desk-length HDMI leads are too short: a projector across a presentation room, a screen separated from an equipment rack or a display in a larger AV space. Because the cable contains active electronics, it needs to be connected in the marked direction. Check the full route and test the exact source, display and audio arrangement before completing an installation. Its rating gives compatible equipment a high-bandwidth connection; it does not add capabilities to the equipment itself.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cfigure style=\"margin:0;background:#fff;border:1px solid #d7e7dd;border-radius:14px;overflow:hidden;\"\u003e\u003cimg loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0581\/3780\/4899\/files\/ugreen-55508-product-1.webp?v=1790150741\" alt=\"UGREEN 55508 HD183 fibre optic HDMI 2.1 cable with aluminium connectors\" style=\"display:block;width:100%;max-width:100%;height:auto;max-height:480px;object-fit:contain;\"\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection style=\"padding:28px clamp(18px,4vw,32px);background:#fff;border-top:1px solid #dce9e1;\"\u003e\u003ch2 style=\"margin:0 0 16px;color:#168346;font-size:clamp(1.35rem,2.5vw,1.8rem);line-height:1.25;\"\u003eKey features\u003c\/h2\u003e\n\u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(min(100%,230px),1fr));gap:14px;\"\u003e\n\u003carticle style=\"background:#fff;border:1px solid #cfe3d6;border-top:4px solid #168346;border-radius:12px;padding:18px;\"\u003e\u003ch3 style=\"margin:0 0 8px;color:#168346;font-size:1.08rem;\"\u003e30-metre installation length\u003c\/h3\u003e\n\u003cp style=\"margin:0;\"\u003eBridge a longer source-to-display route for home cinema, conference-room or presentation equipment.

HDMI 2.1 version?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eYes. SKU 55508 is the HD 183 active optical HDMI cable in the 30m length, with up to 48Gbps bandwidth and support for compatible 8K at 60Hz systems. Check the complete routed distance before ordering, including vertical sections and access behind equipment. Other lengths can share the HD 183 family name, so the SKU and length are the useful details when comparing listings or planning an installation.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eWhy do the Source and Display markings matter?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eThe main video signal travels through this active optical cable in a defined direction. Source connects to the computer, console, media player or relevant HDMI output; Display connects to the TV, monitor or projector. If you reverse the cable, normal video operation will not work. Identify the ends before pulling it along the route, and keep their labels accessible until the final connection has been tested.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eCan I use the cable with a 4K screen or older HDMI equipment?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eYou can use it between compatible HDMI devices at a mutually supported mode. The source and display choose the usable resolution and refresh rate; the 8K capability does not force a lower-resolution screen to accept an unsupported signal. Check any adapters or intermediate AV equipment as well. If changing settings, start with a mode both devices support, confirm a stable picture and then select the desired output.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eWhat is required to display 8K at 60Hz?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eAn 8K-capable source and display are required, together with compatible HDMI ports and settings throughout the connection. The content or application must also provide the intended resolution. A receiver, switch or adapter between them can restrict the available mode, even when the cable itself supports the bandwidth. Test the complete equipment chain at the intended settings before final installation; the cable cannot upgrade a 4K output or display into an 8K one.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eHow does eARC fit with a directional cable?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eeARC is an HDMI audio-return feature, and it requires compatible eARC ports on the TV and audio equipment. The Source and Display labels still determine the main video direction; they should not be swapped casually to chase an audio setting. When connecting an AV receiver and TV, follow the devices' connection instructions and enable the appropriate audio-return settings. Test your exact TV, receiver or soundbar arrangement before securing a long cable run.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eCan I run it through a wall or ceiling?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003ePlan the route carefully and confirm that the chosen cable and installation method meet the requirements for that space. A long cable or PVC jacket alone does not establish a concealed-installation rating. Keep the HDMI heads protected, leave gentle bends and avoid crushing or sharply folding the run. Test both picture and audio before fixing anything permanently, and leave suitable access at each end for connection and later servicing.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eCan the cable be cut, joined or extended?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eTreat it as a complete active optical assembly with electronics at its ends. It is not intended to be cut and terminated like bulk installation cable. An extra HDMI coupler, extension or wall plate adds another connection and may limit performance, so do not assume the original rating applies to a modified chain. Measure carefully, choose the required length and test any unavoidable intermediate components before completing the route.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #cfe3d6;border-radius:10px;margin:10px 0;overflow:hidden;\"\u003e\u003csummary style=\"cursor:pointer;padding:15px 18px;font-weight:700;color:#173d2e;background:#f6f9f7;\"\u003eWhat should I try if the display flickers or reports no signal?\u003c\/summary\u003e\u003cdiv style=\"padding:16px 18px;\"\u003eConfirm cable direction and the selected HDMI input first, then check that both plugs are fully seated. Test a lower supported resolution to separate basic connection issues from a demanding output mode. Temporarily remove switches, wall plates or adapters if practical. Try the source and display directly with a known-working connection, then rebuild the intended setup step by step. Check device firmware and HDMI input settings if the issue appears only in a particular mode.\u003c\/div\u003e\u003c\/details\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Ugreen","offers":[{"title":"Default Title","offer_id":67607337337065,"sku":"55508","price":6578.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/6639\/6905\/files\/ugreen-55508-product-1_460f518d-4e7e-45ff-958b-5ecef99fb00e.webp?v=1790839454","url":"https:\/\/www.teckpot.com\/products\/ugreen-hdmi-8k-60hz-fiber-optic-cable-male-to-male-aluminium-shell-30m-55508","provider":"TeckPot","version":"1.0","type":"link"}
