The JBX88347 ST/ST Duplex Singlemode Fiber Patch Cable represents enterprise-grade connectivity solutions for demanding network environments. This 5-meter cable is engineered to deliver reliable, high-speed fiber optic communication with minimal signal degradation. **Technical Excellence:** Feturing a precision 9/125 singlemode core with G.657.A1 glass fiber, this patch cable provides outstanding performance characteristics. The insertion loss specification of ≤0.35dB ensures minimal signal attenuation over the 5-meter distance, with typical performance at just 0.15dB. Return loss of ≥20dB guarantees superior signal reflection management. Attenuation testing confirms performance at both 1310nm and 1550nm wavelengths, meeting ANSI/TIA/EIA-455-171-A-2001 standards. **Premium Construction:** The 1.8mm outside diameter provides a compact footprint ideal for cable management in tight spaces. OFNR riser-rated jacketing ensures fire safety compliance and durability in vertical building runs. Duplex configuration with ST/UPC connectors enables Type A to B crossover transmission, the industry-standard for duplex patch cords. **Compliance & Certification:** TAA (Trade Agreements Act) compliant for government and institutional purchasing. Fully RoHS/ELV directive compliant (2002/95/EC), meeting environmental standards for electronics manufacturing and disposal. **Ideal Applications:** • Data center networking • Telecommunications infrastructure • Campus area networks (CAN) • Building backbone connections • Telecom equipment interconnects • DWDM system connections **Why Choose This Cable:** Unlike standard multimode cables, singlemode fiber supports longer distances with higher bandwidth. This makes it essential for telecommunications providers, ISPs, and enterprise networks requiring reliable long-haul transmission. The duplex configuration maximizes efficiency by enabling simultaneous bi-directional communication through a single cable. **Value & Availability:** Ships quickly from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC). Free standard shipping on orders exceeding $99. Custom lengths available to meet specific network requirements. Backed by a 90-day limited warranty for peace of mind. Invest in proven fiber optic technology that meets international standards and delivers exceptional performance for your critical network infrastructure.
