The JBX42999 90-meter LC/UPC to LC/UPC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations requiring extended cable lengths with exceptional signal integrity. Manufactured to exacting standards and available from multiple US distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC), this cable delivers reliable performance for mission-critical telecommunications applications. **Technical Excellence & Performance** This simplex singlemode cable features a robust 9/125 micron core specifically engineered for long-distance single-mode transmission. The G.657.A1 glass fiber provides outstanding attenuation characteristics: 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm wavelengths. With measured insertion loss of ≤0.35dB typical (0.15dB nominal) and return loss ≥20dB, the cable meets stringent ANSI/TIA/EIA-455-171-A-2001 testing standards, ensuring optimal optical performance across extended distances. **Design & Construction** The distinctive yellow OFNR (riser-rated) jacket provides flame-resistant protection suitable for vertical installations in commercial buildings while maintaining a compact 1.8mm outside diameter. The straight-through polarity configuration ensures predictable signal transmission for straightforward point-to-point connections. LC/UPC connectors offer superior return loss and low insertion loss characteristics ideal for high-density network environments. **Compliance & Certification** TAA (Trade Agreements Act) compliant and certified under EU Directive 2002/95/EC (RoHS/ELV), this cable meets government procurement requirements and environmental sustainability standards. The commodity classification as an optical accessory with harmonization code 8544.70.0000 streamlines procurement and regulatory documentation. **Applications & Use Cases** Ideal for datacenter backbone connectivity, long-span network segments, telecommunications infrastructure, and specialized single-strand fiber applications. The 90-meter length accommodates extensive cable runs in large facilities while the simplex configuration supports dedicated transmission paths for security-critical or specialized network architectures. **Warranty & Support** Backed by a 90-day limited warranty and backed by free standard shipping on orders exceeding $99, this cable provides exceptional value for professional installers and network administrators. Custom lengths are available upon request for specialized applications. The JBX42999 combines proven singlemode fiber technology with TAA compliance, making it an essential component for government, enterprise, and telecommunications networks demanding reliability and regulatory adherence.
