The JBX42327 80-meter SC/APC to FC/UPC duplex singlemode fiber patch cable is an essential component for modern telecommunications, data center, and enterprise networking infrastructure. This professional-grade optical cable is engineered to deliver superior performance in demanding signal transmission applications where reliability and signal quality are paramount. Key Technical Features: This duplex patch cable utilizes 9/125 singlemode fiber with G.657.A1 glass fiber composition, providing excellent bend-loss characteristics and minimal signal attenuation. The cable achieves insertion loss performance of ≤0.35dB at 1550nm (typical 0.15dB), with return loss exceeding 20dB, ensuring clean signal transmission across long distances. The specifications comply with rigorous ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing. Design and Durability: The cable features a protective 1.8mm outside diameter jacket with OFNR (Optical Fiber Non-Conductive Riser) rating, suitable for installation in vertical cable runs and plenum spaces. The distinctive yellow jacket provides visual identification and reduces installation errors. The duplex configuration with Type A to B crossover polarity (industry standard) makes this cable compatible with most network equipment requiring SC/APC and FC/UPC connector pairs. Compliance and Sustainability: The JBX42327 is TAA (Trade Agreements Act) compliant, making it suitable for government and institutional procurement requirements. The cable meets RoHS and EU Directive 2002/95/EC specifications, ensuring environmental responsibility without compromising performance. Applications: Ideal for long-distance backbone connections, service provider networks, laboratory testing environments, and enterprise data center deployments. The 80-meter length accommodates substantial cable runs between equipment racks and across facility spaces. Custom Configuration: Available in custom lengths to meet specific installation requirements, providing flexibility for unique network topologies. Warranty and Support: Backed by a 90-day limited warranty and eligible for free standard shipping on orders exceeding $99. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery.
