The JBX42643 SC/APC to LC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity solutions for mission-critical network installations. At 12 meters in length, this cable provides optimal reach for connecting network equipment while maintaining signal quality across both 1310nm and 1550nm wavelengths. Technical Excellence: Constructed with 9/125 singlemode glass fiber meeting G.657.A1 specifications, this cable delivers superior performance characteristics. Attenuation is measured at 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, ensuring minimal signal loss across extended distances. The insertion loss specification of ≤0.35dB (with typical performance of 0.15dB) and return loss of ≥20dB exceed industry standards for reliable data transmission. Compliance & Standards: Full TAA compliance makes this cable suitable for government and federal projects. RoHS/ELV certification ensures environmental responsibility, while testing conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 guarantees consistent quality. The OFNR-rated yellow jacket meets fire safety requirements for plenum and riser installations. Optimal Design: The 1.8mm outer diameter facilitates easy routing through tight spaces without compromising durability. The Type A to B crossover polarity configuration is standard for duplex patch cords, eliminating compatibility concerns. Yellow jacket coloring provides visual identification in complex network installations, reducing deployment errors. Applications: Ideal for data centers, telecommunications facilities, enterprise networks, and fiber-to-the-premises (FTTP) installations. The duplex configuration supports simultaneous bidirectional communication, essential for full-duplex network operations. Value Proposition: Manufactured in Taiwan, US, or China with multiple domestic shipping locations (California, Texas, South Carolina) ensuring rapid delivery. Free standard shipping on orders exceeding $99 reduces total acquisition costs. The 90-day limited warranty provides confidence in long-term reliability. Custom Solutions Available: Beyond the standard 12-meter configuration, custom lengths are available to meet specific installation requirements, providing flexibility for diverse network topologies.
