The JBX43449 90-meter FC/APC to FC/UPC simplex singlemode fiber patch cable represents a professional-grade solution for modern networking infrastructure. Engineered to meet the stringent demands of telecommunications, data centers, and enterprise networks, this cable delivers consistent performance across critical applications. **Technical Excellence:** Built with 9/125 singlemode fiber core technology, this cable ensures minimal signal degradation over extended distances. The G.657.A1 glass fiber specification provides optimal performance while maintaining compatibility with existing infrastructure. Tested to ANSI/TIA/EIA-455-171-A 2001 standards, the cable demonstrates exceptional attenuation rates: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths, with typical insertion loss of just 0.15dB. **Professional Features:** The FC/APC-to-FC/UPC connector configuration supports both angle-polished and ultra-polished terminations, offering flexibility for diverse network requirements. The return loss specification of ≥20dB ensures signal integrity and minimizes reflections that could degrade network performance. The straight-through polarity design simplifies installation and integration. **Compliance & Safety:** Full TAA compliance qualifies this cable for government and institutional procurement. RoHS/ELV compliance demonstrates commitment to environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser) rating ensures safe installation in building risers without additional conduit. **Practical Advantages:** The distinctive yellow jacket provides intuitive cable identification, reducing installation errors. At 1.8mm outside diameter, the cable balances durability with manageable routing. Available in custom lengths beyond the standard 90 meters, this solution adapts to your specific installation requirements. **Value Proposition:** Shipped from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC), this cable offers rapid deployment. Free standard shipping on orders exceeding $99 reduces overall project costs. The 90-day limited warranty provides confidence in long-term reliability. **Applications:** Ideal for telecommunications networks, data center interconnections, telecommunications closet installations, and any application requiring reliable, standards-compliant singlemode fiber connectivity. Whether upgrading legacy systems or building new infrastructure, this cable delivers the performance professionals demand.
