The JBX88345 3-meter ST/ST duplex singlemode fiber patch cable is a professional-grade solution designed to meet the demanding requirements of modern network infrastructure. Built with precision-engineered 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers superior signal integrity essential for long-distance telecommunications and high-speed data transmission. **Superior Performance Specifications:** This patch cable achieves insertion loss of ≤0.35dB at 1310nm wavelength (typical 0.15dB) and ≤0.35dB at 1550nm, making it ideal for both short-reach and long-haul applications. The return loss rating of ≥20dB ensures minimal signal reflection, critical for maintaining data integrity. All performance metrics are verified in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance and Quality Assurance:** The cable is fully TAA (Trade Agreements Act) compliant, meeting requirements for government and defense applications. It carries RoHS/ELV certification per EU directive 2002/95/EC, ensuring environmental responsibility. The OFNR (Optical Fiber Non-Conductive Riser Rated) jacketing provides building-code compliance for installation in vertical runs and plenum spaces. **Design and Durability:** The compact 1.8mm outside diameter minimizes cable bulk while the white PVC jacket resists UV degradation and provides visual identification. Type A to B crossover polarity configuration (standard for duplex patch cords) simplifies installation. The cable ships in protective packaging and includes a 90-day limited warranty. **Versatile Applications:** Perfect for datacenter backbone connections, telecommunications infrastructure, enterprise campus networks, and laboratory environments. Available in custom lengths to accommodate specific deployment requirements. Ships quickly from multiple US locations with free standard shipping on orders over $99. **Maintenance:** Prevent contamination by maintaining protective dust caps on connectors. Store in dry conditions away from extreme temperatures. The robust construction ensures years of reliable service in professional environments.
