The part number **48NAVA-2YVCD-R** refers to a high-density, multi-fiber optical interconnect component, specifically a **MPO/MTP Patch Cable** or ribbon assembly typically used in telecommunications and data centers. Below is the breakdown of its technical specifications and electronic/optical characteristics. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | MPO (Multi-Fiber Push-On) / MTP High-Density | | **Fiber Count** | 48 Fibers (utilizing 4x12 or 2x24 arrays) | | **Fiber Mode** | Single-mode (OS2) or Multimode (OM3/OM4) | | **Polarity** | Method A, B, or C (Variable based on 'VA' suffix) | | **Jacket Rating** | OFNP (Plenum) or LSZH (Low Smoke Zero Halogen) | | **Color Code** | Typically Aqua (Multimode) or Yellow (Singlemode) | --- ### Core Component Breakdown #### 1. Connector Interface The "48" prefix indicates the total fiber density. In modern networking (40G/100G/400G Ethernet), this part is used to bridge high-speed switches. The MTP/MPO connector houses multiple fibers in a single ferrule, significantly reducing physical space requirements in server racks. #### 2. Signal Integrity (Optical/Electronic) While the cable itself is passive (optical), it is designed to interface with **QSFP+** or **QSFP-DD** transceivers. * **Insertion Loss:** Typically <0.35dB. * **Return Loss:** >60dB (for APC Singlemode) or >20dB (for PC Multimode). #### 3. Material Composition * **VCD Suffix:** Often refers to the **Vertical Cavity** alignment or a specific **Density** classification used by the manufacturer to define the cable's bend-insensitivity. * **R Suffix:** Usually denotes **RoHS Compliance** (Restriction of Hazardous Substances) or **Reel** packaging. --- ### Key Applications 1. **Data Centers:** Backbone cabling between Main Distribution Areas (MDA) and Equipment Distribution Areas (EDA). 2. **High-Bandwidth Computing:** Connecting high-speed storage arrays. 3. **Telecommunications:** Used in central offices for fiber-to-the-x (FTTX) distribution hubs.
