The JBX85185 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity solutions for demanding network infrastructures. This 1.5-meter cable combines precision engineering with practical design, making it an essential component for modern fiber optic systems. **Technical Excellence** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers industry-leading performance metrics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal degradation, while return loss ≥20dB provides superior signal quality. Attenuation rates of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm meet stringent telecommunications standards, making this cable suitable for both traditional and next-generation optical networks. **Design and Compliance** The distinctive yellow jacket serves dual purposes: visual identification in complex cable runs and safety visibility. The 1.8mm outside diameter provides flexibility without compromising durability. Riser-rated (OFNR) jacketing certification ensures compliance with building codes and fire safety regulations, critical for installations in commercial and industrial environments. TAA (Trade Agreements Act) compliance makes this cable eligible for government contracts and public sector projects. RoHS and ELV directives certification confirms environmental responsibility and safety standards compliance. **Connector Configuration** Feauring SC/UPC to ST/UPC connectors with Type A to B crossover polarity, this duplex configuration is the standard for most fiber optic patch applications. The Type A to B arrangement eliminates the need for separate crossover cables, simplifying installations and reducing inventory costs. **Practical Applications** Ideal for data center migrations, telecommunications infrastructure, campus network expansions, and equipment interconnections. The 1.5-meter length provides optimal reach for patch panel to equipment connections without excess cabling. **Quality Assurance** Every cable is attenuation-tested per ANSI/TIA/EIA-455-171-A standards and backed by a comprehensive 90-day limited warranty. Manufactured in Taiwan, the US, or China with consistent quality control, and shipped from strategically located distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. **Custom Solutions Available** While this 1.5m configuration addresses most standard requirements, custom lengths are available for specialized installations. Bulk packaging (10x10x10) accommodates large-scale deployments with volume pricing advantages. Free standard shipping on orders exceeding $99 reduces total project costs. This fiber patch cable represents the convergence of performance, compliance, and reliability—essential characteristics for mission-critical network infrastructure.
