The JBX86202 55-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for professional-grade network connectivity. Designed specifically for single-mode fiber optic applications, this cable bridges SC and ST connectors with exceptional precision and reliability. **Technical Specifications:** Built with a 9/125 singlemode core and G.657.A1 fiber grade, the JBX86202 delivers superior performance across telecommunications wavelengths. Attenuation measures 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, ensuring minimal signal degradation over extended distances. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss ≥20dB meets stringent ANSI/TIA/EIA standards (ANSI/TIA/EIA-455-171-A-2001). **Key Features:** The duplex configuration with Type A to B crossover polarity provides the most common and compatible patch cord arrangement for network deployments. OFNR riser-rated jacketing ensures compliance with building safety codes while the 1.8mm diameter accommodates tight routing in modern data centers. TAA compliance makes this cable suitable for government and institutional projects requiring domestic or allied-nation manufacturing. **Applications:** Ideal for telecom companies, data centers, enterprise networks, and service providers requiring dependable signal transmission. The 55-meter length serves mid-range backbone connections, equipment interconnections, and facility-wide network runs. **Quality Assurance:** RoHS/ELV certified for environmental compliance.
