The JBX43073 12-meter LC/APC to SC/UPC simplex singlemode fiber patch cable represents a premium solution for professional-grade fiber optic networking. Designed for telecommunications, data center, and enterprise installations, this cable delivers exceptional performance and reliability. **Technical Specifications:** This simplex fiber patch cable features a 9/125 singlemode core constructed to G.657.A1 standards, specifically engineered for long-distance, high-bandwidth signal transmission. The cable exhibits minimal attenuation at both 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km) wavelengths, supporting both traditional and extended-spectrum applications. Insertion loss is rated at ≤0.35dB with typical performance of just 0.15dB, while return loss exceeds 20dB—both critical parameters for signal quality and network reliability. The straight-through polarity design ensures straightforward installation without confusion about directional flow. **Construction and Durability:** The cable features a robust 1.8mm outside diameter with plastic accessories and OFNR (Optical Fiber, Non-conductive, Riser Rated) jacketing. This riser rating permits installation in vertical cable runs between building floors, making it suitable for multi-story installations. The durable yellow jacket provides high visibility for identification and management in congested server rooms or network closets. **Compliance and Standards:** Fully TAA (Trade Agreements Act) compliant and RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets government procurement requirements and environmental regulations. Performance testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent, measurable quality. **Application and Use Cases:** Perfect for connecting LC/APC-terminated equipment to SC/UPC components in telecommunications networks, this simplex configuration works exceptionally well in point-to-point applications where unidirectional transmission is required. Commonly used in fiber-to-the-desktop (FTTD) installations, equipment patch panels, and specialized laboratory applications. **Shipping and Support:** Available with free standard shipping on orders exceeding $99, shipped from multiple US locations (Danville CA, Fort Worth TX, or Beaufort SC) for expedited delivery. Custom lengths are readily available to eliminate waste and reduce installation time. The 90-day limited warranty provides peace of mind for your investment. **Custom Configuration:** While this listing specifies 12 meters, custom lengths are available to match your exact installation requirements, from short patch runs to extended backbone cables.
