The JBX88214 65m ST/ST Duplex Singlemode Fiber Patch Cable represents a precision-engineered solution for demanding fiber optic network applications. Featuring a robust 9/125 singlemode core with G.657.A1 glass fiber composition, this cable delivers industry-leading performance specifications that exceed ANSI/TIA/EIA standards. Key Technical Advantages: This duplex configuration cable achieves exceptional insertion loss ratings of ≤0.35dB at 1310nm and ≤0.35dB at 1550nm, ensuring minimal signal degradation over the full 65-meter length. Return loss performance of ≥20dB provides superior signal integrity and minimizes reflections that could compromise data transmission quality. The cable's 1.8mm outside diameter maintains a compact profile while the 2mm duplex spacing accommodates standard patch panel installations. Construction and Compliance: The yellow OFNR (Optical Fiber Non-Conductive Riser) jacketing satisfies fire safety requirements for vertical runs and plenum installations. RoHS/ELV compliance ensures environmental responsibility, while TAA certification meets government procurement requirements for federal and institutional buyers. The Type A to B crossover polarity configuration is the most common duplex standard, eliminating compatibility concerns. Applications and Use Cases: Ideal for enterprise data centers, telecommunications facilities, and network backbone infrastructure requiring reliable long-distance singlemode transmission. The 65-meter length accommodates horizontal runs in large facilities while maintaining signal quality. Perfect for campus networks, carrier-grade installations, and redundant backup circuits. Shipping and Warranty: Enjoy free standard shipping on orders exceeding $99 from strategically located warehouses in California, Texas, and South Carolina. Every cable includes a 90-day limited warranty. Custom lengths available for specialized installations. Maintenance Tip: Store in dry conditions and protect connectors with dust caps when not in use to maximize cable lifespan and maintain performance specifications.
