The JBX42631 1m SC/APC to LC/UPC Duplex Singlemode Fiber Patch Cable represents professional-grade optical connectivity engineered for critical network infrastructure. This TAA-compliant solution delivers the performance and reliability demanded by telecommunications, data center, and enterprise network professionals. **Technical Excellence** Features 9/125 singlemode fiber construction with G.657.A1 glass composition, optimized for long-distance, high-bandwidth signal transmission. The duplex configuration integrates two fiber strands in a single cable assembly, simplifying installation while maintaining exceptional performance. Insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while ≥20dB return loss provides superior signal integrity. **Connector Specifications** The SC/APC to LC/UPC configuration with Type A to B crossover polarity accommodates most standard duplex patch cord applications. SC/APC connectors provide excellent mechanical durability, while LC/UPC connectors offer compact form-factor advantages in space-constrained environments. **Installation & Safety** Riser-rated (OFNR) jacketing ensures safe installation in wall cavities and plenum spaces. The 1.8mm outer diameter provides flexibility for cable routing in tight spaces. All components comply with RoHS/ELV directives and EU directive 2002/95/EC standards. **Reliability & Compliance** Tested to ANSI/TIA/EIA-455-171-A standards with attenuation specifications of 1310nm: 0.25dB/km or 1550nm: 0.35dB/km. TAA compliance ensures eligibility for government and institutional procurement. Backed by a 90-day limited warranty. **Versatile Deployment** Ideal for telecommunications infrastructure, fiber-to-the-premise (FTTP) deployments, data center backbone connections, and network equipment interconnects. Available in custom lengths for specialized applications. Ships from multiple US locations with free standard shipping on orders exceeding $99. **Why Choose This Cable?** Combines professional-grade performance with proven reliability. Low insertion loss minimizes signal regeneration requirements, reducing system complexity and operational costs. TAA compliance expands procurement options for regulated environments.
