The part number **A-DXFXXLPIII-FP-R** follows the nomenclature for high-performance industrial fiber optic adapters or connectivity components, typically associated with **Amphenol** or similar precision interconnect manufacturers. Below is a technical breakdown of the electronic and mechanical characteristics of this component series. --- ## 1. Technical Specifications This component is designed for high-density fiber optic patching environments. | Feature | Specification | | :--- | :--- | | **Component Type** | Fiber Optic Adapter / Coupler | | **Fiber Type** | Singlemode (OS2) or Multimode (OM3/OM4) | | **Connector Style** | DX (Duplex) | | **Form Factor** | LC (Lucent Connector) | | **Mounting Type** | Flange Mount / Panel Mount | | **Alignment Sleeve** | Zirconia Ceramic (High Precision) | | **Compliance** | RoHS, REACH | --- ## 2. Part Number Breakdown While specific internal codes can vary by manufacturer, the typical anatomy of this string is as follows: ### A - DX - F - XX - LP - III - FP - R * **A**: Usually designates the series or manufacturer prefix (e.g., Amphenol). * **DX**: **Duplex**. Indicates the adapter accommodates two fiber connections simultaneously. * **F**: **Flanged**. Indicates the housing has "ears" for screw-mounting to a patch panel. * **XX**: Placeholder for fiber type (e.g., SM for Singlemode, MM for Multimode). * **LP**: **Low Profile**. Designed to take up less vertical space in high-density racks. * **III**: Designates the generation or specific internal configuration (e.g., Type 3). * **FP**: **Footprint**. Standardized footprint for interchangeability. * **R**: **RoHS Compliant**. --- ## 3. Key Electronic & Physical Attributes ### Precision Alignment Inside the adapter is a **Zirconia Ceramic sleeve**. Even though the component doesn't use electricity to function, its "electronic" importance lies in **Insertion Loss (IL)** management. It ensures the fiber cores (8-9 microns for singlemode) are perfectly aligned to prevent signal degradation. ### Signal Integrity * **Low Insertion Loss:** Typically < 0.2dB. * **High Return Loss:** Ensures that light reflections do not travel back into the laser source, which could cause hardware errors in active equipment (SFP modules). ### Mechanical Durability * **Durability:** Rated for >500 matings. * **Operating Temperature:** -40°C to +85°C, making it suitable for both data centers and industrial environments. --- ## 4. Usage Example In a standard network architecture, this part is used in a **Patch Panel (ODF)**. ```mermaid graph LR A[Switch SFP+ Module] --> B[Fiber Patch Cable] B --> C{A-DXFXXLPIII-FP-R Adapter} C --> D[Backbone Trunk Cable] D --> E[Remote Server Room] ``` ---
