The JBX87180 SC/ST duplex singlemode fiber patch cable represents a premium solution for connecting singlemode fiber optic equipment in enterprise, data center, and telecommunications environments. This meticulously engineered 0.5-meter cable combines reliability, performance, and regulatory compliance in a compact form factor. **Technical Excellence:** Featuring a 9/125 micron singlemode core with G.657.A1 glass fiber composition, this cable delivers superior signal transmission characteristics. The specification of ≤0.35dB insertion loss at 0.15dB typical ensures minimal signal degradation, critical for long-distance data transmission. Return loss of ≥20dB provides excellent reflection performance, reducing signal interference and maintaining network integrity across 1310nm and 1550nm wavelengths. **Robust Construction:** The duplex configuration with Type A to B crossover polarity accommodates the most common network topologies. The 1.8mm outer diameter casing is protected by riser-rated (OFNR) jacketing, meeting UL fire safety standards for in-building applications. RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility and regulatory adherence. **Connector Quality:** SC/UPC and ST/UPC polished connectors provide repeatable, low-loss connections with reduced back-reflection. The mechanical design ensures secure seating and consistent performance across thousands of mating cycles. **Deployment Ready:** This cable ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. The 90-day limited warranty provides confidence in product reliability. Custom lengths are available for specialized network configurations, and case packaging accommodates bulk deployments. **Ideal Applications:** Perfect for fiber optic networks, telecommunications infrastructure, medical imaging systems, industrial automation, and high-speed data centers where signal integrity is paramount.
