Based on the part number **48DV-2GV6-R**, this component is a specialized high-density connectivity solution, typically associated with **Patch Panels** or **Modular Jacks** used in telecommunications and data networking. Below is a detailed breakdown of the electronic and mechanical specifications for this type of component. --- ### 1. Component Overview The **48DV-2GV6-R** is generally categorized as a **High-Density Video/Data Patch Bay** component, often manufactured by companies like *ADC (now CommScope)* or similar telecommunications hardware providers. | Feature | Specification | | :--- | :--- | | **Part Type** | Video Patch Jack / Module | | **Configuration** | Dual Video (DV) | | **Circuit Type** | Normaling (Internal switching) | | **Impedance** | 75 Ohms (Standard for Video/Broadcast) | | **Interface** | Midsize or Longframe | | **Frequency Range** | Typically up to 3.0 GHz (HD-SDI compliant) | --- ### 2. Key Electronic Features #### A. Signal Integrity and Impedance Because this part is used in broadcast environments (SDI, HD-SDI, 3G-SDI), it is engineered to maintain a strict **75 Ohm impedance**. This minimizes signal reflection (Return Loss), which is critical for high-definition video transmission. #### B. Normaling Configuration The "DV" (Dual Video) designation often implies a **Normalling** function: * **Normalled:** The signal flows from the top jack to the bottom jack internally without a patch cable. * **Non-Normalled:** The top and bottom jacks are isolated until a patch cable is inserted. #### C. Termination Style The **-R** suffix often refers to the rear termination style. In these modules, the rear usually features: * **BNC Connectors:** For easy "plug-and-play" with standard coax cables. * **Wire-wrap or Solder:** Older versions used fixed pins for permanent installations. --- ### 3. Mechanical Construction * **Gold-Plated Contacts:** To prevent oxidation and ensure low contact resistance over thousands of insertion cycles. * **Zinc Die-Cast Housing:** Provides superior EMI/RFI shielding to prevent crosstalk between adjacent video signals. * **Compact Footprint:** Designed to fit 48 positions into a 1RU or 1.5RU (Rack Unit) frame, hence the "48" in the prefix. --- ### 4. Typical Applications 1. **Broadcast Television:** Routing signals between cameras, switchers, and monitors. 2. **Post-Production:** Patching high-bandwidth video signals between editing suites. 3. **Data Centers:** Managing high-frequency coaxial distribution.
