The JBX42522 ST/APC to ST/APC duplex fiber patch cable represents enterprise-grade optical connectivity engineered for critical network infrastructure. This 10-meter cable combines superior performance specifications with regulatory compliance, making it ideal for telecommunications, data center, and campus network environments. **Performance Specifications:** Built with 9/125 singlemode fiber exceeding G.657.A1 standards, this duplex cable delivers exceptional attenuation characteristics: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss remains at or below 0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB—specifications tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Key Features:** • Duplex configuration for simultaneous bidirectional transmission • Type A to B crossover polarity for standard network applications • 1.8mm outside diameter for space-efficient routing • Bright yellow jacketing enables quick cable identification and management • OFNR riser-rated construction supports in-building installation • TAA-compliant for government and institutional procurement • RoHS/ELV certified for environmental compliance **Applications:** Ideal for connecting network equipment, telecommunications systems, CATV systems, and fiber-to-the-premises (FTTP) installations. The singlemode configuration supports long-distance, high-bandwidth applications requiring superior signal fidelity. **Technical Advantages:** Singlemode fiber delivers lower attenuation and greater bandwidth than multimode alternatives, enabling longer transmission distances without signal degradation. The ST/APC connector design provides excellent return loss and minimal back-reflection, critical for system stability. **Compliance & Warranty:** Fully compliant with TAA requirements and RoHS directive 2002/95/EC, backed by 90-day limited warranty. Available in custom lengths for specialized installations. Ships from multiple US locations with free standard shipping on orders exceeding $99.
