The **W2CE-1A2-R/N** is a specialized electronic component, typically categorized as a high-frequency or high-speed connector/terminator, often used in telecommunications and data networking hardware. ### 1. Component Overview This part number generally refers to a specific series of **High-Speed Interconnects** or **SFP (Small Form-factor Pluggable) Cage/Connector assemblies**. These are critical for enabling modular optical or copper network connections. | Feature | Specification | | :--- | :--- | | **Component Type** | SFP/SFP+ Connector / Cage Assembly | | **Port Configuration** | 1x1 (Single Port) | | **Orientation** | Right Angle / Horizontal | | **Mounting Type** | Through-Hole or Press-fit (depending on exact sub-spec) | | **Plating** | Tin or Gold over Nickel (R/N suffix often indicates RoHS/Nickel) | --- ### 2. Breakdown of the Part Number While naming conventions can vary slightly by manufacturer (such as Foxconn, Amphenol, or TE Connectivity), the code usually breaks down as follows: * **W2CE**: The series identifier (High-speed interface family). * **1A2**: Indicates the physical configuration (Single port, specific pinout layout). * **R/N**: * **R**: Often stands for **RoHS Compliant**. * **N**: Often refers to **Nickel Plating** or a specific material finish on the cage to prevent electromagnetic interference (EMI). --- ### 3. Technical Functions The W2CE-1A2-R/N performs three primary roles in a PCB (Printed Circuit Board) design: 1. **High-Speed Data Transmission**: Designed to handle data rates common in Gigabit Ethernet, Fibre Channel, and InfiniBand. 2. **EMI Shielding**: The "Cage" (the metal housing) acts as a Faraday cage to prevent electromagnetic interference from leaking out of or into the high-speed signal path. 3. **Mechanical Stability**: Provides the physical latching mechanism for SFP transceivers, ensuring they stay seated during vibration or thermal expansion. --- ### 4. Common Applications * **Network Switches**: Connecting fiber optic modules to the main board. * **Servers**: High-speed I/O interfaces for data centers. * **Storage Area Networks (SAN)**: Facilitating fast data transfer between drives and controllers. * **Telecommunication Base Stations**: Used in RRU (Remote Radio Units) for mobile networks. --- ### 5.
