The JBX43427 5-meter FC/APC to FC/UPC simplex fiber patch cable represents professional-grade optical connectivity for demanding networking applications. Engineered with precision manufacturing and rigorous quality control, this singlemode fiber cable delivers consistent, high-performance signal transmission across critical infrastructure. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass specifications, this cable meets ANSI/TIA/EIA standards for attenuation testing. Performance metrics include insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring minimal signal degradation. Operating across 1310nm and 1550nm wavelengths with attenuation of 0.25 dB/km and 0.35 dB/km respectively, this cable handles diverse telecom applications. **Connectivity Features:** The FC/APC to FC/UPC connector configuration bridges angle-polished and ultra-polished equipment, enabling seamless integration across mixed optical environments. The simplex design carries single fiber strands, ideal for unidirectional signal transmission in point-to-point installations. **Physical Design & Safety:** The bright yellow jacket (1.8mm outside diameter) enables quick visual identification in dense cable installations. OFNR riser rating allows safe pathway installation through building cavities and wall runs. Custom length availability accommodates specific deployment requirements. **Compliance & Standards:** TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets government procurement standards and environmental regulations. Backed by a 90-day limited warranty, it's manufactured in Taiwan, US, or China with consistent quality across all sources. **Applications:** Ideal for telecommunications infrastructure, data centers, carrier networks, and enterprise optical deployments requiring reliable signal transmission over short distances. Suitable for equipment upgrades, testing environments, and temporary installations. **Shipping & Availability:** Stocked at multiple fulfillment centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Packaged in secure 10x10x10 case configuration for safe delivery.
