The part number **48SV2-RHCDT-R** typically refers to a high-density, vertical, shielded **SFP (Small Form-factor Pluggable) Connector/Cage assembly**, often manufactured by companies like Foxconn or specialized interconnect providers. These components are foundational in networking hardware, such as switches, routers, and network interface cards (NICs). --- ## Technical Specifications & Features | Feature | Description | | :--- | :--- | | **Component Type** | SFP (Small Form-factor Pluggable) Cage & Connector | | **Orientation** | Vertical (90-degree mount relative to the PCB) | | **Port Configuration** | 1x1 (Single Port) | | **Shielding** | Full Metal Shielding for EMI/RFI protection | | **Mounting Type** | Press-fit or Through-hole (Standard for high-speed signal integrity) | | **Data Rate Support** | Typically optimized for 1Gbps up to 10Gbps+ (SFP+) | --- ## Breakdown of the Part Number Logic While specific manufacturer codes vary, the nomenclature generally follows this pattern: 1. **48SV2**: Series identifier for vertical SFP interconnects. 2. **RH**: Often denotes **RoHS Compliant** and **Halogen-Free** material properties. 3. **CDT**: Specific mechanical features (e.g., specific clip type, heat sink compatibility, or gold plating thickness). 4. **R**: Usually indicates **Tape & Reel** packaging for automated SMT assembly. --- ## Core Components of the Assembly ### 1. The Metal Cage The "Cage" acts as the housing for the SFP transceiver module. It provides mechanical support and, most importantly, **Electromagnetic Interference (EMI)** shielding. It ensures that the high-frequency signals do not interfere with other components on the PCB. ### 2. The Connector Interface Inside the cage is a 20-pin electrical interface. This is where the gold fingers of the SFP module make contact with the host PCB. ### 3. Thermal Management The "CDT" variant often includes features for heat dissipation, allowing for air-flow or the attachment of a clip-on heat sink to manage the thermal output of high-speed transceivers. --- ## Common Applications * **Data Centers:** High-speed server racks. * **Telecommunications:** Base stations and switching centers. * **Storage Area Networks (SAN):** Connecting Fiber Channel switches. * **Industrial Ethernet:** Robust networking in factory environments.
