The JBX42181 LC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Manufactured with precision engineering, this 1-meter cable combines superior optical performance with practical installation features. Technical Excellence: The cable features a 9/125 singlemode core with G.657.A1 glass fiber construction, optimized for long-distance signal transmission with minimal loss. Insertion loss specifications of ≤0.35dB (with typical performance at 0.15dB) and return loss ≥20dB exceed industry standards, ensuring signal integrity across both 1310nm and 1550nm wavelengths. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm provide consistent performance across standard telecom bands. Connector Configuration: The Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring seamless compatibility with existing infrastructure. LC/APC connectors provide angled polished surfaces for reduced back-reflection, while FC/UPC connectors offer proven reliability in enterprise environments. Installation & Compliance: The 1.8mm outside diameter and OFNR riser rating allow safe deployment in building plenum spaces. The bright yellow jacketing facilitates quick identification in cable runs. Full RoHS/ELV compliance and TAA certification make this cable suitable for government and enterprise procurement requirements. Flexibility & Support: Available in custom lengths beyond the standard 1m option, the JBX42181 adapts to diverse installation scenarios. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a comprehensive 90-day limited warranty. Ideal Applications: Perfect for datacenter migrations, telecom infrastructure upgrades, enterprise campus networks, and any installation requiring reliable single-mode fiber connectivity with angled connector performance characteristics.
