The JBX91202 55-meter SC/ST duplex singlemode fiber patch cable represents the ideal solution for organizations requiring reliable, long-distance optical fiber connectivity with government compliance requirements. This professionally-engineered cable combines proven SC/UPC and ST/UPC connector technology with premium singlemode fiber specifications to deliver consistent performance in mission-critical network environments. Key Technical Advantages: The 9/125 micron singlemode core with G.657.A1 glass fiber ensures minimal signal degradation over extended distances. Attenuation testing complies with ANSI/TIA/EIA-455-171-A-2001 standards, with typical insertion loss of only 0.15dB and maximum 0.35dB. Return loss exceeds 20dB, ensuring signal integrity for sensitive applications. The duplex configuration transmits independent signals on both fiber strands simultaneously, maximizing bandwidth efficiency. Compliance and Safety: TAA compliant certification meets Buy American requirements for government and institutional buyers. Full RoHS/ELV compliance eliminates hazardous materials. The OFNR (Optical Fiber, Nonconductive, Riser) jacket rating permits installation in vertical cable runs and plenum spaces, providing superior fire safety compared to standard jackets. Practical Installation Benefits: The 1.8mm compact diameter reduces congestion in existing cable management systems. Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring compatibility with standard network equipment. The 55-meter length serves enterprise campuses, data center floor distributions, and inter-building connections. Applications: Data center backbone connectivity, telecommunications infrastructure, university and corporate campus networks, disaster recovery site links, and high-reliability mission-critical systems. Quality Assurance: 90-day limited warranty provides peace of mind. Custom lengths available for specialized applications. Ships from US distribution centers with free standard shipping on orders exceeding $99.
