The JBX88342 ST/ST singlemode fiber patch cable represents premium connectivity for demanding optical network environments. This 1.5-meter duplex cable combines exceptional performance with enterprise-grade reliability, making it the ideal choice for telecommunications professionals, data center operators, and network integrators. **Key Technical Specifications:** Constructed with a 9/125 singlemode fiber core and G.657.A1 rated glass fiber, this cable delivers superior signal integrity across standard telecom wavelengths. The remarkably low insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while the ≥20dB return loss maintains signal quality in bi-directional applications. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm exceed industry standards, providing future-proof performance for advanced optical systems. **Professional Grade Construction:** The cable features ST/UPC connectors configured in Type A to B crossover polarity—the most common duplex patch cord configuration. The OFNR riser-rated white jacket provides fire safety compliance and durability in both horizontal and vertical cable runs. At just 1.8mm in outer diameter, this cable integrates seamlessly into existing infrastructure without requiring costly reconfiguration. **Compliance & Reliability:** TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets government procurement standards and environmental regulations. All performance metrics are tested and verified in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across every shipment. Backed by a 90-day limited warranty and manufactured in Taiwan, the US, or China, this cable represents exceptional value for mission-critical applications. **Applications:** Ideal for data center interconnects, telecommunications networks, fiber-to-the-premises (FTTP) installations, and high-speed computing environments where signal integrity is paramount. The flexibility of custom length availability makes this solution adaptable to unique infrastructure requirements. **Ordering Benefits:** Enjoy free standard shipping on orders over $99 with convenient fulfillment from multiple US locations (Danville, CA; Fort Worth, TX; and Beaufort, SC), ensuring rapid delivery to your facility.
