300M Fiber DP Extender 8K@60Hz / 4K@240Hz Lossless Over Optical Fiber

Connect one computer or other source with a DisplayPort output to one DisplayPort display. The product page lists compatibility with Windows, macOS and Linux. For remote control, the source also needs a USB port for the transmitter's USB Type-A to Type-B connection. Maximum video performance depends on the GPU, operating system, display and cables supporting the requested format.

Use one continuous OM4 multimode duplex LC-LC fiber patch cable that meets IEC 60793-2-10. Connect the transmitter and receiver directly for distances up to 300 m (984 ft). Do not route the link through a fiber switch, media converter, optical splitter or other active network device. Keep the LC connector end faces clean and avoid excessive bending.

The maximum supported format is 7680×4320 at 60Hz. Compatible lower formats include 3840×2160 at 60Hz, 120Hz, 144Hz and 240Hz. Actual performance depends on the source GPU, operating system, display, DP cables, fiber link, HDCP requirements and the capabilities negotiated across the complete connection.

No. DKE30SS-M25 is a hardware DisplayPort and USB extension system and does not require a DisplayLink driver or TESmart control software. The computer may still need its normal graphics, USB or peripheral drivers.

The extender automatically presents the connected display's capabilities to the source; this model has no EDID DIP switch or manual EDID mode. Whenever possible, connect and power the receiver and display before starting or reconnecting the source. If the source selects the wrong resolution, power-cycle the extender and display, then reconnect or restart the source.

The receiver USB ports are intended for USB 2.0 keyboard and mouse input, including a compatible wireless keyboard-and-mouse receiver. General-purpose USB devices such as storage drives, webcams, printers and audio interfaces are not confirmed by the supplied documentation and should be connected directly to the computer unless compatibility has been verified.

Connect speakers or headphones to the receiver's stereo output, then select the DisplayPort display or corresponding digital-audio device in the computer's playback settings. This connection provides stereo output only; it does not support microphone input or bidirectional analog audio.

Yes. Connect one supplied 12V power adapter to the transmitter and the other to the receiver. Fully seat and lock both 5.5×2.1 mm DC connectors. Use only the supplied adapters or replacements with matching voltage, polarity, connector size and current capacity.

A red Power indicator means the unit detects its 12V input. A blue Video Signal indicator means the unit detects an active video signal. If red is off, check the adapter, outlet and locking DC connection. If both units have power but blue is off, check the source DP output, DP cables, fiber link and display input.

Connect the computer's DP output and USB port to the transmitter. Link the transmitter directly to the receiver with one OM4 multimode duplex LC-LC fiber cable. Connect the receiver to the display by DP, then attach the keyboard, mouse and optional speakers or headphones. Power both units with the supplied 12V adapters and confirm that the red Power and blue Video indicators are on.

Confirm that both Power indicators are on and that the source is awake and outputting through the connected DP port. Reseat the DP and duplex LC connectors, select the correct display input, and verify a direct OM4 link without unsupported intermediate devices. Test short known-good DP and OM4 cables at 1920×1080@60Hz before increasing the format.

Confirm that the GPU output, display input, DP cables and selected display mode all support the requested format. Update the graphics driver, test a lower resolution or refresh rate, use short DP 1.4 cables at both ends, and keep the OM4 link within 300 m. For protected content, every component in the chain must support HDCP 2.2.

Confirm that the computer is connected to the transmitter by both DP and USB. Reconnect the input devices, test them directly on the computer, try another computer.
