KVM Extender ATEN True 4K DP/HDMI Optical KVM 300m – Transmitter & Receiver, DisplayPort/HDMI, USB, 300 m

The ATEN True 4K DP/HDMI Optical KVM 300m (CE980) is a fiber-optic KVM extender kit consisting of a transmitter and receiver that extends DisplayPort or HDMI KVM signals up to 300 meters. It delivers True 4K video (3840 x 2160 and 4096 x 2160 at 60 Hz, 4:4:4) with HDR10 and HDCP 2.3 compliance, supports USB 2.0 peripherals at 480 Mbit/s, RS-232 control, and embedded digital audio formats including Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio. The unit uses a 2-in-1 DisplayPort/HDMI combo connector to simplify connections at both local and remote consoles and is designed for environments that require stable, interference-resistant long-distance signal transmission.

Advantages

The CE980 provides pristine True 4K image quality with HDR10 and full 4:4:4 chroma sampling over a single fiber-optic link, ensuring accurate color and high contrast for professional video workflows. Its combo DisplayPort/HDMI connector allows flexible display configurations without additional adapters. Long-distance fiber transmission (up to 300 m) offers EMI resistance and stable operation, while dual-console capability with configurable privilege modes (Auto/Local and Auto/Remote) enables collaborative access or exclusive control when needed.

Suitable for

• Healthcare control rooms and medical imaging stations
• Post-production and broadcast facilities requiring true 4K monitoring
• Manufacturing and industrial control systems with EMI concerns
• Security and surveillance setups needing long-distance KVM extension

When it may not be suitable

This optical KVM extender is not intended for applications that require wireless connectivity or where fiber cabling is impractical. It also may be unnecessary for simple desktop setups that do not need long-distance extension, True 4K support, or professional audio passthrough.

How to use

Install the transmitter near the source computer and the receiver at the remote console. Connect the source video output to the transmitter's combo connector using either a DisplayPort or HDMI cable and connect local and remote keyboards/mice to the USB ports. Link the transmitter and receiver with a compatible fiber-optic cable, connect power supplies (12 V DC), and power on both units. Use the Auto/Local or Auto/Remote pushbutton to choose shared access or to give privileged control to either the local or remote console. Configure display and audio settings on the host system as needed for True 4K and HDR output.

What to consider before purchase

• Availability and routing of fiber-optic cabling between source and remote locations
• Compatibility of connected displays (DisplayPort or HDMI) and required cables/adapters
• Need for dual-console access and privilege switching in your workflow
• Power availability for two 12 V DC adapters at transmitter and receiver locations
• Required audio formats and USB peripheral support (USB 2.0 at 480 Mbit/s)

Recommendations

For reliable 4K HDR performance, use high-quality certified fiber-optic cable and ensure connected displays support the desired resolutions and HDR settings. When deploying in EMI-prone environments, route fiber away from high-noise electrical equipment and verify RS-232 connections and USB devices for compatibility before final installation.
