Dvigear DVI-28xxx-AOC DisplayPort-Mdp 1.4 Active Optical Cables User Guide
Introduction
DVI Gear’s Hyper Light mDP display cables are designed to support DisplayPort 1.4, offering a massive data rate of up to 32.4 Gbps (HBR3). This makes them perfect for ultra-high-definition applications, effortlessly supporting 4K @ 60Hz (4:4:4) and 8K @ 30Hz (4:4:4) resolutions—even over long distances up to 100 meters.
Product Usage Instructions
- Connect the Transmitter (TX) end of the cable to the DisplayPort source device.
- Connect the Receiver (RX) end of the cable to the display device.
- Insert the TX end of the cable into the docking connector labeled Source and insert the RX end of the cable into the docking connector labeled Display.
- Use the locking pin to ensure that the docking connector is secured to the cable.
- Take care not to force the cable to bend beyond its minimum bend radius of 35 mm.

How to Use
Step-by-Step Usage Instructions:
RX (Receiver): This end connects to your display device, like a monitor, projector, or video wall.
Important: These cables are unidirectional. Reversing the TX and RX ends will prevent proper operation.
Power-On Sequence
To ensure smooth handshake and communication:
Turn ON your display device first.
Turn ON any switchers or extenders in the signal path.
Cable Bending & Handling
Maintain a minimum bend radius of 35mm (1.38 inches) to prevent damage.
Installation Instructions
The DVI‑28xxx‑AOC cable includes an integrated transmitter module (labeled “TX” and “S”) and a receiver module (labeled “RX and “D”). The video signals in this cable travel over internal optical fibers and are UNIDIRECTIONAL. Other signals (AUX Channel, HPD, power, etc.) travel over internal copper wires.
- Connect the Transmitter end of the cable (labeled TX, S, Source) to the source device.
- Connect the Receiver end (labeled RX, D, Display) to a display or projector.
- This cable draws power from the connected DisplayPort source, which eliminates the need for an external power supply.
- Test the system to ensure proper performance.

Detaching and attaching the full-size DisplayPort Docking Connector to the Cable End(4)
- Hold the DisplayPort Connector with the Latch Release Button facing upwards.
- Ensure that the TX cable end (side labeled TX and S facing up) is seated in the Source Docking Connector (p.n. DVI-28000-TX).
Key Features:
- DisplayPort 1.4 compliant
- HDCP 1.4 / 2.2 compatibility
- Support for 4K and 8K resolutions
- Compact, lightweight form factor
- No need for external power supply
Their flexibility and durability make them an ideal fit for mission-critical setups where flawless image quality and reliability are paramount.
