The part number **48DV-4CVG-R** refers to a high-performance **Category 6 (Cat6) Shielded (FTP/STP) Patch Panel**, typically manufactured by networking hardware companies like Signamax. This component is crucial for telecommunications and data center infrastructure. --- ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Category** | Cat 6 (Augmented or Standard) | | **Port Density** | 48 Ports | | **Shielding Type** | Fully Shielded (Foiled Twisted Pair) | | **Form Factor** | 2U Rack Mount (Standard 19-inch) | | **Termination** | 110-type IDC or Toolless (model dependent) | | **Material** | Cold-rolled steel with grounding lugs | --- ## Key Components and Electronic Functions ### 1. The Printed Circuit Board (PCB) Inside the metal housing, the ports are mounted on a high-grade PCB. The layout is engineered to minimize: * **Near-End Crosstalk (NEXT):** Interference between adjacent wire pairs. * **Return Loss:** Signal reflections caused by impedance mismatches. ### 2. Shielding and Grounding (The "V-Shape" Design) The "DV" in the prefix often denotes a high-density or specific physical orientation. * **Electromagnetic Interference (EMI) Protection:** The metal casing and shielded jacks prevent external electrical noise from disrupting data signals. * **Grounding Bar:** The "-R" variant usually includes a rear cable management bar that acts as a common ground point for the drain wires of the STP cables. ### 3. IDC (Insulation Displacement Contacts) The rear of the panel features gold-plated or nickel-plated contacts where the horizontal cabling is punched down. These are designed for: * **Gas-tight connections:** Preventing oxidation over time. * **Wire Gauge Support:** Typically supports 22-26 AWG solid copper wires. --- ## Usage Scenario This specific part is used in environments with high electronic noise (like factory floors or dense server rooms) where **48 ports** need to be managed in a compact **2U space**. 1. **Incoming Data:** Shielded cables from various rooms enter the rack. 2. **Termination:** Cables are stripped and punched into the back of the 48DV-4CVG-R. 3. **Patching:** Short patch cords connect the front ports of this panel to a network switch. ---
