The JBX42481 ST/APC to ST/UPC Duplex Fiber Patch Cable represents the gold standard in single-mode optical connectivity. Designed for telecommunications professionals, data center technicians, and network integrators, this 1-meter cable delivers the reliability and performance demanded by mission-critical infrastructure. **Superior Performance Specifications** With a typical insertion loss of just 0.15dB and maximum of 0.35dB, this cable minimizes signal degradation over long-distance transmissions. The ≥20dB return loss specification ensures excellent signal reflection characteristics. Testing conducted per ANSI/TIA/EIA-455-171-A standards guarantees consistent quality across all wavelengths—1310nm at 0.25dB/km and 1550nm at 0.35dB/km attenuation rates. **Smart Design Features** The yellow OFNR-rated (Optical Fiber Non-conductive Riser) jacket provides easy visual identification in crowded cable bundles while meeting fire safety codes for in-building installation. The 1.8mm outside diameter balances durability with flexibility for tight routing requirements. Duplex configuration with Type A to B crossover polarity accommodates most standard network applications without additional equipment. **Compliance & Reliability** Full TAA compliance makes this cable suitable for government contracts and federal procurement. RoHS/ELV directive adherence ensures environmental responsibility. The 90-day limited warranty and rigorous quality testing provide peace of mind for critical installations. **Versatile Applications** Ideal for campus networks, ISP backhaul, telecommunications facilities, research institutions, and data centers. Available in custom lengths beyond the standard 1m offering, accommodating specific installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Why Choose This Cable** When signal integrity matters, G.657.A1 glass fiber construction provides the foundation for reliable, high-speed data transmission. The combination of excellent specifications, compliance certifications, and professional-grade construction makes this duplex patch cable an intelligent choice for networks demanding maximum uptime and performance.
