The part number **2295000-R** typically refers to a specialized electronic connector assembly, most notably associated with high-speed connectivity solutions from manufacturers like **TE Connectivity**. Below is a detailed breakdown of the technical specifications and components related to this part. --- ### 1. General Overview The 2295000-R is a **QSFP28 (Quad Small Form-factor Pluggable 28)** cage assembly. It is designed to house transceiver modules used in high-speed networking equipment such as switches, routers, and servers. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | QSFP28 Cage Assembly | | **Data Rate** | Up to 100 Gbps (4 x 25 Gbps) | | **Port Configuration** | 1x1 (Single Port) | | **Mounting Type** | Through-hole / Press-fit | | **Termination Method** | Compliant Pin | | **Thermal Management** | Includes Integrated Heat Sink | | **EMI Shielding** | Internal EMI springs and external gaskets | --- ### 3. Key Electronic Components & Design Features #### A. The Cage Structure The "Cage" is a metal housing that provides mechanical support for the pluggable module. It is usually made of a copper alloy with nickel plating to ensure durability and electrical conductivity for grounding. #### B. Thermal Management (Heat Sink) Because 100G data transmission generates significant heat, the "R" suffix often denotes a specific configuration that includes a **Heat Sink**. * **Material:** Aluminum or Copper. * **Fin Style:** Pin fins or square fins to maximize airflow from the system fans. #### C. EMI (Electromagnetic Interference) Protection To maintain signal integrity at 100 Gbps, the part features: * **EMI Springs:** These contact the bezel of the equipment to ensure a continuous ground path. * **Shielding:** Prevents high-frequency noise from escaping the port or entering the system. #### D. Light Pipes (Optional) Depending on the specific sub-variation of the 2295000 series, these may include optical light pipes that channel light from LEDs on the PCB to the front panel to indicate link status and activity. --- ### 4. Typical Applications * **Data Centers:** High-density networking switches. * **Telecommunications:** Base stations and core routers. * **Storage Systems:** High-speed SAN (Storage Area Network) arrays. ---
