The JBX43597 ST/APC to FC/APC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for critical telecommunications infrastructure. This 80-meter cable is engineered to meet the stringent demands of modern optical networks while maintaining exceptional signal fidelity and durability. **Technical Excellence**: Built with G.657.A1 glass fiber, this cable features a 9/125 micron singlemode core that supports long-distance transmission with minimal signal degradation. The cable achieves industry-leading insertion loss of just 0.15dB typical (maximum 0.35dB) and return loss exceeding 20dB, ensuring pristine signal quality across your network. **Professional-Grade Construction**: The 1.8mm outer diameter is encased in riser-rated (OFNR) jacketing, providing flame resistance and environmental protection suitable for installation in commercial building spaces. The bright yellow color aids in cable identification and management, reducing installation errors. **Compliance & Standards**: TAA-compliant design ensures this cable meets government procurement requirements. Full RoHS/ELV compliance confirms environmental responsibility and regulatory adherence. Attenuation performance is tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliable performance specifications. **Wide Wavelength Support**: Designed for both 1310nm and 1550nm windows, this cable maintains 0.25dB/km attenuation at 1310nm and 0.35dB/km at 1550nm, supporting diverse network architectures and applications. **Practical Advantages**: The simplex (single-strand) configuration provides directional transmission for dedicated signal paths. Straight-through polarity ensures straightforward installation without specialized knowledge. Custom lengths are available for specialized applications beyond the standard 80-meter offering. **Reliability & Support**: Backed by a 90-day limited warranty and shipped from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC), this product ensures quick delivery and responsive customer service. Free standard shipping on orders exceeding $99 reduces total cost of ownership. **Applications**: Ideal for fiber-to-the-premises (FTTP) installations, data center interconnects, telecommunications network expansions, and equipment patch panels requiring ST/APC to FC/APC connectivity with guaranteed performance specifications.
