Cable alargador USB-C Ochno O-EC-20 — 20 m, soporte DisplayPort 1.4 Alt Mode

Ochno O-EC-20 is a 20-meter USB-C extension cable designed to extend the reach of USB-C devices while maintaining video transmission using DisplayPort 1.4 Alt Mode. The cable carries USB-C signaling and DP Alt Mode video over a long distance, enabling connection between compatible laptops, tablets, docking stations and displays without relocating equipment. The construction is intended for fixed AV installations, meeting rooms and workstation setups where a longer, single-cable run is required.

Advantages

The cable supports DisplayPort 1.4 Alt Mode, which allows transmission of high-resolution video from a USB-C source to a compatible display. At 20 meters length, it eliminates the need for multiple adapters or intermediate extenders in many installations. The single-cable design preserves a tidy connection path and reduces clutter compared with multiple shorter cables and adapters. The extension format keeps the source device and display at their existing ports while increasing physical separation between them.

Suitable for

• Conference rooms and presentation setups requiring long cable runs
• Fixed AV installations in classrooms, auditoriums or meeting spaces
• Workstations where the host device and display are positioned far apart
• Temporary event layouts that use USB-C video sources

Key specifications

• Cable type: USB-C extension with DisplayPort 1.4 Alt Mode support
• Length: 20 m
• Video mode: DisplayPort 1.4 Alt Mode over USB-C
• Purpose: Video and USB-C signal extension over long distance
• Typical applications: AV installations, presentations, extended workstation connections

How to use

Connect the male USB-C plug of the extension cable to the USB-C output of the source device (laptop, tablet or docking station) and attach the female USB-C end to the display’s USB-C input or to a short USB-C to DisplayPort/HDMI adapter if the display accepts a native DP/HDMI connector. Ensure both the source and display support DisplayPort Alt Mode over USB-C. Power delivery and USB data behaviors depend on the connected devices and any intervening adapters; verify device capabilities before use. Route the cable to avoid sharp bends and secure it along its path to prevent strain on connectors.

Recommendations

For reliable video performance at long distances, use devices and displays that explicitly support DisplayPort 1.4 Alt Mode over USB-C. Avoid excessive bending or kinking of the cable, and keep the cable away from strong electromagnetic sources. If using adapters to convert to native DisplayPort or HDMI, choose high-quality adapters that support the desired resolution and refresh rate.
