The **M2AS1-4411-R/N** is a specialized electronic component, typically categorized as an **SFP (Small Form-factor Pluggable) Stacked Connector** or a high-speed networking interface assembly. These parts are fundamental in telecommunications and data center hardware. --- ## 1. Component Overview This part number usually refers to a **2x1 Stacked SFP Connector/Cage assembly**. It is designed to house SFP modules (transceivers) that convert electrical signals into optical or high-speed copper signals. ### Key Specifications | Feature | Description | | :--- | :--- | | **Port Configuration** | 2x1 (Stacked: one port on top of the other) | | **Connector Type** | SFP (Small Form-factor Pluggable) | | **Mounting Type** | Through-Hole / Press-Fit | | **Orientation** | Right Angle | | **Lightpipes** | Usually integrated (indicated by R/N suffix variations) | --- ## 2. Core Electronic Features ### A. High-Speed Signal Integrity The internal pins are engineered to handle data rates commonly associated with **SFP+ (10 Gbps)** or higher. The design minimizes "crosstalk" (interference between the top and bottom ports) and maintains impedance at **100 Ohms**. ### B. EMI Shielding The metal "cage" surrounding the connector serves as an Electromagnetic Interference (EMI) shield. This is critical in high-density networking environments to prevent the high-frequency signals from interfering with nearby components. ### C. Press-Fit Technology Most parts in this series use **Press-Fit (Elastic) pins**. - **Advantage:** No soldering is required to attach the cage to the PCB. - **Reliability:** Provides a strong mechanical bond and high-quality electrical connection that is resistant to thermal expansion. ### D. Integrated Lightpipes The "R/N" designation often refers to the specific configuration of **Lightpipes**. These are clear plastic tubes that channel light from LEDs on the motherboard to the front faceplate, providing status indicators (Link/Activity) for each port. --- ## 3.
