The JBX88395 70-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for organizations requiring dependable long-distance fiber optic connectivity. This professional-grade cable is constructed with a 9/125 micrometer core optimized for singlemode transmission, enabling signal propagation over extended distances with minimal signal degradation. Key Performance Characteristics: This cable delivers exceptional optical performance with insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB, ensuring signal integrity across long cable runs. Attenuation specifications of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm comply with industry standards for high-speed telecommunications and data center applications. Design and Construction: The duplex configuration features Type A to B crossover polarity—the most common standard for duplex patch cords. The 1.8mm outside diameter and OFNR riser-rated purple jacketing provide flexibility in routing while meeting fire safety requirements. G.657.A1 glass fiber construction ensures compatibility with modern network infrastructure. Compliance and Certification: TAA compliant manufacturing and RoHS/ELV certification make this cable suitable for government and enterprise procurement. Available in custom lengths for specialized installations, shipped from multiple US locations with free standard shipping on orders over $99. Applications: Ideal for fiber-to-the-premises (FTTP) networks, telecommunications backbone infrastructure, data center interconnections, and long-distance signal transmission requiring reliable performance. The 70-meter length accommodates substantial separation between network equipment without signal loss. Warranty and Support: 90-day limited warranty provides confidence in product quality and performance reliability.
