Introduction
With the development of display technology, the demand for ultra-high-resolution content is growing rapidly. While 4K is widespread, 8K has become the new standard for environments requiring extreme detail and clarity. Traditional DisplayPort (DP) extension solutions—whether using copper cables, Cat6, or standard HDMI/DP extenders—are encountering significant distance limitations.
• Standard HDMI/DP copper cables achieve the following at 4K@60Hz typically 10–20 meters.
• High-quality Cat6/HDBaseT extenders can reach 50–100 meters.
Beyond these distances, repeaters or signal boosters are required; otherwise, video flickering, artifacts, or black screens may occur. This increases system complexity and potential sources of error.
The TESmart DKE30SS-M25 Single-link DisplayPort fiber extenders overcome these limitations. By using OM4 multimode fiber does it enable a point-to-point transfer of 8K@60Hz (DSC) over 300 meters and offers This makes it an industry-leading solution for professional environments that require high-resolution video over long distances.
Technical Highlights
8K@60Hz (DSC) support
-
Delivers exceptionally clear image reproduction with smooth motion and vibrant colors.
-
Display Stream Compression (DSC) ensures lossless image quality even over long transmission distances.
-
Ideal for medical imaging, broadcasting and control rooms where precision and frame rate are crucial.
OM4 fiber enables 300-meter transmission
-
Point-to-point architecture guarantees stable long-distance performance.
-
Avoids multiple repeaters, reduces latency and signal degradation.
-
Supports high-resolution, long-range applications while simplifying cabling and management.
Breakthroughs & Applications
Limitations of traditional solutions
-
Copper or Cat6 extenders are limited in distance (standard copper: 10–20 m, high-end Cat6/HDBaseT: 50–100 m).
-
Longer distances require repeaters, which increases cabling complexity and potential sources of error.
-
For large campus areas, operating rooms or exhibition halls, traditional solutions often cannot cover the entire range in one connection.
Value of the 300-meter extension
-
Unique remote coverage: Transmits signals up to 300 meters without a repeater.
-
High resolution & low latency: Point-to-point connection ensures stable 8K@60Hz (DSC) without loss of detail.
-
Cost- & Maintenance reduction: Fewer repeaters and simplified cabling reduce hardware investments and maintenance costs.
Practical Use Cases
-
Large campus grounds/control rooms/security monitoring: Single-link transmission covers multiple buildings or an entire campus and offers a cleaner, more reliable installation than 100-meter extenders, which require multiple repeaters.
-
Remote surgery/High-precision medical imaging: Operating rooms or diagnostic centers receive 8K video directly from data centers, thus ensuring low latency and precise image sharpness.
-
Exhibitions/Broadcasting/Large Venues: Remote screens can be directly connected to the control system and deliver stable 8K content without the latency or signal loss caused by multi-stage extenders.
-
Data centers/Financial trading floors: A single fiber optic link supplies multiple terminals, simplifying cabling and reducing operating costs.
