The **2XU-Z1Z1-R** is a specific part number typically associated with high-performance **DisplayPort 1.4 active optical cables (AOC)** or specialized interface modules used in high-bandwidth digital signaling. --- ### 1. Component Overview This part is designed to bridge the gap between copper-based transmission and fiber-optic speed, primarily used for long-distance 8K video transmission without signal degradation. | Feature | Specification | | :--- | :--- | | **Interface Type** | DisplayPort 1.4 (Standard) | | **Max Bandwidth** | 32.4 Gbps (HBR3) | | **Max Resolution** | 8K @ 60Hz / 4K @ 144Hz | | **Technology** | Active Optical (Hybrid Fiber/Copper) | | **Power Supply** | Bus-powered (No external power usually required) | --- ### 2. Internal Electronic Structure The "Active" nature of this part means it contains integrated circuits (ICs) within the connector heads. * **VCSEL (Vertical Cavity Surface Emitting Laser):** Converts the incoming electrical DisplayPort signals into light pulses for fiber transmission. * **Photo-Diode Receiver:** Located at the display end to convert light pulses back into electrical signals. * **Clock and Data Recovery (CDR):** Internal chips that clean up signal jitter to ensure synchronization at high frequencies. * **Hybrid Architecture:** * **Optical Fibers:** Carry the high-speed video data. * **Copper Wires:** Carry the low-speed handshake signals (EDID, HDCP) and provide power to the internal lasers. --- ### 3. Key Electronic Benefits 1. **EMI/RFI Immunity:** Because the primary data travels via glass fiber, it is immune to electromagnetic interference from nearby machinery or wireless devices. 2. **Low Latency:** The conversion process happens at near-light speeds, making it suitable for real-time medical imaging or high-end gaming. 3. **No Signal Booster Needed:** Unlike standard copper DP cables that fail after 3-5 meters, this part allows for transmission up to 100 meters. --- ### 4. Technical Pinout (DP 1.4 Standard) The electronic interface follows the standard 20-pin DisplayPort layout: | Pin | Name | Description | | :--- | :--- | :--- | | 1-12 | Main Link | High-speed lanes (Optical) | | 13-14 | Config/GND | Grounding and detection | | 15-17 | AUX Channel | Handshake/Control (Copper) | | 18-20 | Hot Plug / Power | 3.3V Power and detection | ---
