The JBX42329 90-meter SC/APC to FC/UPC duplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking applications. Engineered to deliver consistent performance in demanding environments, this cable combines superior optical characteristics with practical design features for real-world deployments. **Technical Excellence:** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers exceptional optical performance. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure minimal signal loss across extended distances. The remarkably low insertion loss (≤0.35dB typical at 0.15dB) and excellent return loss (≥20dB) exceed industry standards, making it ideal for precision applications. **Robust Design:** The 1.8mm outside diameter and OFNR riser-rated jacket provide durability and flame resistance suitable for building risers and plenum applications. The yellow jacket enables quick visual identification in complex installations, reducing troubleshooting time and installation errors. **Compliance & Reliability:** Full TAA compliance and RoHS/ELV certification ensure suitability for government and regulated commercial environments. Tested according to ANSI/TIA/EIA-455-171-A-2001 standards and backed by a 90-day limited warranty, this cable meets the highest industry requirements. **Versatile Applications:** Ideal for telecommunications networks, data centers, campus networks, and fiber-to-the-premises (FTTP) installations. The duplex configuration supports Type A to B crossover polarity for standard duplex patch cord applications. Custom lengths available for specialized deployment requirements. **Value & Support:** With free standard shipping on orders over $99 and multiple US warehouses ensuring quick delivery from Danville, CA, Fort Worth, TX, or Beaufort, SC, you get both quality and convenience. This professional-grade solution provides reliable fiber connectivity for critical network infrastructure.
