The JBX42980 8-meter LC/UPC singlemode fiber patch cable represents a superior solution for professional networking and telecommunications applications. This simplex cable utilizes premium 9/125 singlemode fiber (G.657.A1 grade) specifically engineered for optimal performance in demanding environments. **Performance Specifications:** With measured insertion loss of 0.15dB typical and a maximum of 0.35dB, this cable delivers exceptional signal integrity across standard telecommunications wavelengths (1310nm and 1550nm). Return loss exceeding 20dB ensures minimal signal reflectance, critical for high-speed data transmission and telecommunications networks. All attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards, providing documented proof of quality and reliability. **Design & Construction:** The LC/UPC straight-through connector configuration enables seamless integration with existing infrastructure. The 1.8mm outside diameter with protective yellow OFNR riser-rated jacket provides both flexibility and durability in demanding installation scenarios. The bright yellow color coding simplifies cable management and troubleshooting in complex network environments. **Compliance & Certification:** TAA compliant for U.S. government procurement and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets the stringent environmental and procurement standards required by enterprises, government agencies, and large organizations. Manufactured in Taiwan, the U.S., or China with quality consistency across all production facilities. **Applications:** Ideal for data centers, telecommunications rooms, long-distance signal transmission, fiber-to-the-desk installations, and any application requiring reliable singlemode connectivity. The 8-meter length accommodates typical floor-to-equipment runs while custom lengths are available for specialized requirements. **Value & Support:** Backed by a 90-day limited warranty and offered with free standard shipping on orders exceeding $99. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Professional networking teams trust this cable for mission-critical infrastructure where signal quality and compliance matter.
