The JBX42024 represents a professional-grade solution for demanding fiber optic networking applications. This 65-meter LC/APC to LC/UPC duplex single mode fiber patch cable combines technical excellence with practical reliability, making it an ideal choice for enterprises and service providers requiring robust network infrastructure. **Technical Specifications:** Built with 9/125 single mode fiber core and G.657.A1 glass fiber technology, this patch cable delivers exceptional performance metrics. The insertion loss of ≤0.35dB (0.15dB typical) at both 1310nm and 1550nm wavelengths ensures minimal signal degradation over the 65-meter span. Return loss of ≥20dB provides superior signal reflection characteristics, critical for maintaining signal quality in duplex transmission scenarios. **Design & Construction:** The duplex configuration features two fiber strands in a single assembly, enabling simultaneous bidirectional communication. The Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring compatibility with existing network equipment. The bright yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides excellent visibility in cable runs while meeting UL fire safety standards for plenum and riser applications. The compact 1.8mm outer diameter allows for efficient cable management and routing through tight spaces. **Compliance & Quality:** Fully TAA (Trade Agreements Act) compliant, this cable meets stringent government procurement requirements. RoHS/ELV directives compliance ensures environmental responsibility. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing performance consistency. Backed by a 90-day limited warranty, the cable provides peace of mind for critical network deployments. **Applications:** Ideal for data centers, telecommunications facilities, enterprise networks, and any environment requiring extended single mode fiber runs with superior signal integrity. The 65-meter length serves mid-range connectivity needs while maintaining exceptional signal quality. **Availability & Shipping:** Available in custom lengths to meet specific project requirements. Enjoy free standard shipping on orders exceeding $99, with convenient fulfillment from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC). **Quality Assurance:** Each cable is tested and certified to perform reliably in demanding network environments. The professional-grade construction ensures years of dependable service in high-availability installations.
