The **FLCS-12B-R/Q** refers to a high-performance **Fiber Optic LC Simplex Adapter** (often associated with brands like Panduit or specialized fiber component manufacturers). These components are critical in telecommunications and data networking for aligning and connecting fiber optic connectors. --- ### 1. Technical Specifications The "12B" typically signifies a specific density or housing style, while "R/Q" refers to the color coding and sleeve material. | Feature | Specification | | :--- | :--- | | **Connector Type** | LC Simplex | | **Fiber Mode** | Multimode (OM3/OM4) or Singlemode (depending on sleeve) | | **Sleeve Material** | Zirconia Ceramic or Phosphor Bronze | | **Housing Material** | Thermoplastic (UL 94V-0 rated) | | **Mounting Type** | Snap-in (with integrated clips) or Flange mount | | **Insertion Loss** | Typically < 0.2dB | --- ### 2. Key Electronic & Physical Components #### A. Alignment Sleeve This is the heart of the adapter. * **Zirconia Ceramic:** Used for high-precision Singlemode applications. * **Phosphor Bronze:** Often used in Multimode applications where slightly higher tolerances are acceptable. #### B. Housing (The "12B" Body) The housing is designed to fit into standard patch panels. The "12B" designation often refers to a **Sr./Jr.** footprint or a specific panel cutout size that allows for high-density configurations. #### C. Color Coding (R/Q Suffix) In fiber optics, colors are standardized to prevent cross-connection: * **Aqua (Q):** Usually indicates 10Gig Multimode (OM3/OM4). * **Blue:** Usually indicates Singlemode (OS1/OS2). * **Beige:** Usually indicates standard Multimode (OM1/OM2). --- ### 3. Application Use Cases The FLCS-12B-R/Q is primarily used in: 1. **Fiber Patch Panels:** Connecting backbone cabling to active equipment. 2. **SFP/SFP+ Transceivers:** Interfacing between the cable and the optical module. 3. **Data Centers:** High-density LC connections to save rack space. --- ### 4. Part Number Breakdown (Example) While nomenclature varies slightly by brand, the breakdown usually follows this logic: | Segment | Meaning | | :--- | :--- | | **FLC** | Fiber LC Connector/Adapter style | | **S** | Simplex (Single connection point) | | **12** | Series or internal design revision | | **B** | Bulk pack or specific mounting clip style | | **R/Q** | Color/Material code (e.g., Aqua for OM3/4) |
