The JBX42998 85-meter LC/UPC to LC/UPC singlemode fiber patch cable represents a professional-grade solution for network infrastructure requiring long-distance fiber connectivity. This simplex configuration transmits signals in a single direction, making it ideal for specific network architectures where unidirectional communication is required or preferred. **Technical Specifications:** Built with 9/125 singlemode fiber core, this cable adheres to industry standards for long-distance, single-wavelength transmission. The G.657.A1 glass fiber formulation offers improved macrobend loss characteristics, enabling reliable performance even in space-constrained installations. With a 1.8mm outside diameter, the cable maintains a compact profile while ensuring structural integrity. **Performance Metrics:** Insertion loss specifications of ≤0.35dB at 1550nm and 0.25dB/km at 1310nm demonstrate exceptional signal clarity. Return loss ≥20dB reflects superior connector quality and precision manufacturing. These performance metrics comply with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring compatibility with enterprise-grade network equipment. **Compliance & Safety:** TAA (Trade Agreements Act) compliant designation qualifies this cable for government and federal procurement programs. RoHS/ELV certification confirms absence of restricted hazardous substances, supporting environmental sustainability initiatives. The OFNR (Optical Fiber Non-conductive Riser) rating permits installation in vertical cable runs between floors without conduit, simplifying deployment in multi-story facilities. **Practical Applications:** Ideal for data centers, telecommunications infrastructure, campus networks, and long-distance facility connectivity. The 85-meter length bridges significant distances between equipment racks, buildings, or network nodes while maintaining signal integrity. Available in custom lengths for specialized applications. **Quality Assurance:** Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. 90-day limited warranty provides peace of mind. Free standard shipping on orders exceeding $99 enhances value proposition for bulk purchases. **Packaging:** Come in 10x10x10 case packaging suitable for inventory management and distribution. Yellow jacketing provides visual identification for network management and asset tracking purposes.
