The JBX11431 SC/UPC Female to LC/UPC Male singlemode simplex fiber adapter is an essential optical interconnect solution for professional fiber optic networks. Engineered with precision manufacturing standards, this converter bridges SC and LC fiber connector types while maintaining the integrity of high-speed data transmission over 9/125 singlemode fiber. **Technical Specifications:** Connector Type: SC/UPC (Female) to LC/UPC (Male) conversion Fiber Mode: 9/125 Singlemode Adapter Configuration: Simplex (single-fiber) Construction: One-piece metal design with plastic coupler Dimensions: 4.0" L x 1.0" W x 0.5" H Material: Metal housing with precision-molded plastic components Country of Origin: Vietnam, China Commodity Classification: Optical Accessory (Harmonization Code: 8544.70.0000) **Key Features & Benefits:** **Reliable Connectivity:** The one-piece construction eliminates potential connection points that could introduce signal degradation. Professional-grade couplers ensure low insertion loss and minimal return loss for critical network applications. **Singlemode Precision:** Designed specifically for 9/125 singlemode fiber, this adapter maintains the tight tolerances necessary for long-distance, high-bandwidth telecommunications. Ideal for enterprise networks, ISP backbone connections, and data center interconnects. **Simplex Design Advantage:** The simplex configuration accommodates unidirectional fiber paths, commonly used in applications requiring dedicated transmit and receive fibers. This design is fundamental in many CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) installations. **Durability & Quality Assurance:** Manufactured to RoHS Directive 2002/95/EC compliance standards, ensuring environmental responsibility and reliability. The 90-day limited warranty provides peace of mind for business-critical installations. **Applications:** - Telecommunications network upgrades and migrations - Data center fiber interconnections - Enterprise campus network connectivity - ISP and carrier backbone networks - CWDM/DWDM system deployments - Test and measurement equipment connections **Installation & Maintenance:** Install in clean, dust-free environments. Use appropriate cleaning procedures for fiber end-faces before connection to ensure optimal performance. The adapter's metal construction provides structural stability while the precision coupler maintains optical alignment for consistent signal quality throughout its operational lifespan. **Ordering & Support:** Available with free standard shipping on orders exceeding $99. Ships from distribution centers in Danville, California and Beaufort, South Carolina for rapid delivery nationwide. Backed by professional customer support and a 90-day limited warranty ensuring complete customer satisfaction.
