The JBX88244 65-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for mission-critical telecommunications, data center, and enterprise network environments. Manufactured with precision to exacting specifications, this cable combines exceptional performance characteristics with regulatory compliance and durability. **Technical Excellence**: The 9/125 micrometer core with G.657.A1 glass formulation provides optimal signal transmission with minimal attenuation. Insertion loss of ≤0.35dB (0.15dB typical) ensures signal fidelity over the full 65-meter length, while return loss exceeding 20dB prevents signal degradation from reflections. Performance is independently verified according to ANSI/TIA/EIA-455-171-A-2001 standards. **Durability and Identification**: The 1.8mm outside diameter with red OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides superior protection against environmental stressors while facilitating easy identification in dense fiber installations. Riser-rated jacketing ensures compliance with building codes for plenum and riser applications. **Regulatory Compliance**: TAA (Trade Agreements Act) compliance makes this cable eligible for U.S. government contracts and procurement programs. RoHS/ELV certification (EU Directive 2002/95/EC) ensures environmental responsibility and safety standards compliance. **Flexible Configuration**: The Type A to B crossover polarity is the industry-standard configuration for duplex patch cords, eliminating the need for specialized adapters. Custom lengths are available for applications requiring non-standard distances. **Application Suitability**: Ideal for telecommunications central offices, Internet service provider (ISP) networks, data center backbone connections, enterprise LAN/WAN infrastructure, and scientific research facilities requiring single-mode optical connectivity. The 65-meter length bridges medium-distance requirements without excessive signal loss. **Value and Support**: Backed by a 90-day limited warranty and enjoying free standard shipping on qualifying orders, this cable delivers enterprise-grade performance at competitive pricing. Ships from multiple domestic locations ensuring rapid delivery throughout North America.
