The **KFS-3A-R/Q** typically refers to a specialized high-performance **Optical Fiber Cleaver** (or a specific model series of cleavers) used in fiber optic splicing operations. In these devices, the "electronic parts" are generally minimal compared to fusion splicers, but specific high-end versions include sensors and automated components. Below is an explanation of the components and technical specifications associated with this type of equipment. --- ### 1. Key Technical Components | Component | Function | Material/Type | | :--- | :--- | :--- | | **Circular Blade** | Performs the actual "scoring" of the glass fiber. | Tungsten Steel Alloy | | **Fiber Holder/Slot** | Secures the 250μm or 900μm fiber in place. | Rubberized Clamp / Aluminum | | **Automatic Return Mechanism** | Returns the blade to the starting position after a cut. | Spring-loaded Slider | | **Offcut Collector** | Safely stores shards of glass fiber. | Plastic bin with manual/auto entry | ### 2. Electronic & Electromechanical Features While many cleavers are purely mechanical, models in the **R/Q series** (specifically the "R" often denoting Rotating or Return) may include the following features: #### A. Blade Management System On some high-end iterations, a **Bluetooth module** or **NFC chip** is embedded to communicate with a Fusion Splicer. This allows the splicer to track: * Number of cleaves performed. * Blade wear status. * Automated blade rotation instructions. #### B. Sensors (Advanced Models) If the unit is part of an automated splicing kit: * **Position Sensors:** Detect if the lid is closed to trigger the slide. * **Counter:** A digital or mechanical display used to track the lifespan of the 16-24 position blade. ### 3. Technical Specifications Typical performance metrics for the KFS-3A series: | Parameter | Specification | | :--- | :--- | | **Cleave Angle** | Typically < 0.5° | | **Blade Life** | ~48,000 cleaves (16 positions × 3,000 per pos) | | **Fiber Diameter** | 125μm (Cladding) | | **Coating Diameter** | 250μm ~ 900μm | | **Cleave Length** | 9mm - 16mm (Single Fiber) | --- ### 4. Maintenance of Parts 1. **Cleaning:** Use 99% Isopropyl Alcohol on the rubber pads and the blade edge. 2. **Blade Rotation:** When the cleave angle becomes inconsistent, the "electronic" tracking or manual count indicates it is time to rotate the blade to the next numbered position using a hex wrench. 3. **Spring Tension:** The internal return spring must be kept free of debris to ensure the "R" (Return) function operates smoothly.
