The JBX85191 SC/ST Duplex Singlemode Fiber Patch Cable represents a premium networking solution for organizations requiring reliable, high-speed optical signal transmission. This 6-meter cable combines superior optical performance with practical installation features, making it ideal for telecommunications, data center, and enterprise network environments. Optical Performance & Specifications Built with 9/125 singlemode fiber featuring G.657.A1 glass technology, this patch cable delivers exceptional performance across standard telecom wavelengths. The ultra-low insertion loss of 0.15dB (typical) and ≤0.35dB maximum ensures minimal signal degradation over longer runs. Return loss measurements of ≥20dB provide excellent signal reflection characteristics, critical for maintaining data integrity in high-speed networks. Attenuation specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm demonstrate compliance with ANSI/TIA/EIA-455-171-A-2001 testing standards. Connector Configuration & Compatibility The SC/UPC to ST/UPC connector pairing with Type A-to-B crossover configuration represents the industry-standard duplex arrangement for most network applications. SC connectors offer reliable push-pull locking mechanisms, while ST connectors provide proven compatibility with legacy telecommunications equipment. Both utilize UPC (Ultra Physical Contact) polishing for optimal return loss performance. Construction & Safety Compliance The yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides flame-resistant properties suitable for in-building vertical runs and horizontal cable trays. This riser rating ensures compliance with fire safety codes without requiring expensive conduit installations. The 1.8mm outer diameter balances durability with manageable handling during installation. TAA compliance certification makes this cable eligible for federal and government procurement initiatives. Practical Advantages Available in custom lengths for specific installation requirements, this cable eliminates costly splicing while reducing waste. The distinctive yellow jacket simplifies network administration and troubleshooting by enabling instant visual identification. A comprehensive 90-day limited warranty provides peace of mind, backed by industry-standard quality testing. Free standard shipping on orders exceeding $99 makes bulk procurement economical. Ideal Applications Perfect for upgrading legacy ST-based networks, cross-connecting equipment in data centers, or implementing reliable fiber backbones in enterprise environments where signal quality cannot be compromised. The combination of proven connector technology and modern singlemode fiber makes this cable suitable for both current deployments and future-ready network infrastructure.
