The JBX88356 ST/ST Singlemode Fiber Patch Cable represents the gold standard in fiber optic connectivity solutions. This 25-meter cable delivers enterprise-grade performance for mission-critical network applications, offering reliable signal transmission with minimal signal loss. **Key Technical Features:** Constructed with 9/125 singlemode core fiber and G.657.A1 glass, this duplex patch cable provides superior performance characteristics. The extremely low insertion loss of ≤0.35dB (0.15dB typical) ensures signal integrity over extended distances. Return loss exceeding 20dB guarantees minimal signal reflection, critical for high-speed data transmission. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm accommodate both traditional and modern wavelength requirements. **Construction & Durability:** The cable features a robust 1.8mm outside diameter with riser-rated (OFNR) jacketing, meeting fire safety standards for building installations. The white color finish aids in cable identification and organization. ST/UPC connectors with Type A to B crossover configuration ensure proper polarity alignment for duplex applications. **Compliance & Standards:** Fully TAA compliant for government procurement, this cable meets RoHS and ELV directives (EU 2002/95/EC). All performance metrics are validated per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across production batches. **Ideal Applications:** Perfect for telecommunications infrastructure, data center interconnects, enterprise LAN installations, and backup connectivity solutions. The 25-meter length accommodates medium-distance runs while maintaining signal quality. **What You Get:** Each cable includes a 90-day limited warranty. Custom lengths are available for specialized installations. Free standard shipping applies to orders exceeding $99, with convenient fulfillment from multiple U.S. locations.
