The JBX88246 75-meter ST/ST duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring dependable long-distance fiber optic connectivity. Built to exacting standards, this cable combines advanced glass fiber technology with robust construction to deliver exceptional performance in enterprise, data center, and telecommunications environments. **Technical Excellence:** This cable features a 9/125 singlemode fiber core constructed from G.657.A1 grade glass, specifically designed to minimize signal loss over extended distances. The measured insertion loss of ≤0.35dB (with typical performance at 0.15dB) ensures signal integrity across the full 75-meter span. The return loss specification of ≥20dB provides excellent signal reflection prevention, critical for maintaining data transmission quality. **Compliance & Safety:** Fully TAA-compliant for government and federal procurement requirements, this cable meets EU RoHS directives (2002/95/EC) and ELV standards. The OFNR (Optical Fiber Non-conductive Riser) rated jacket ensures compliance with building fire safety codes while facilitating installation in plenum and riser spaces. **Practical Design Features:** The Type A to B crossover configuration represents the industry standard for duplex patch cord applications, eliminating confusion during installation. The distinctive red jacket provides immediate visual identification in complex cable management scenarios, reducing troubleshooting time and installation errors. The compact 1.8mm outside diameter enables efficient routing through existing cable infrastructure without requiring pathway upgrades. **Performance Specifications:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, this cable delivers consistent attenuation performance across critical wavelengths: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. These metrics ensure reliable performance for both legacy systems and modern dense wavelength division multiplexing (DWDM) applications. **Ideal Applications:** Perfect for data center interconnects, campus network backbones, telecommunications equipment connections, and any scenario requiring extended single-mode fiber runs with uncompromised signal quality. Backed by a 90-day limited warranty and available in custom lengths for specialized installations. **Shipping & Support:** Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with complimentary standard shipping on orders exceeding $99. Professional quality at competitive pricing makes this the smart choice for network infrastructure investments.
