The JBX88403 2m ST/ST Duplex 9/125 Singlemode Fiber Patch Cable is a professional telecommunications solution engineered for demanding network environments. Designed to facilitate high-bandwidth data transmission, this cable combines precision engineering with regulatory compliance to meet enterprise-grade specifications. **Technical Excellence:** This singlemode fiber cable features a 9/125 micrometer core/cladding diameter, ideal for long-distance transmission with minimal signal loss. The G.657.A1 glass fiber specification provides superior bend-insensitivity without compromising performance. Independent testing validates attenuation at 1310nm: 0.25dB/km and 1550nm: 0.35dB/km, exceeding ANSI/TIA/EIA-455-171-A-2001 standards. Insertion loss measures ≤0.35dB (0.15dB typical), while return loss maintains ≥20dB, ensuring pristine signal quality. **Connector Configuration:** Both ends feature ST/UPC (Ultra-Polish Connector) connectors in Type A to B crossover configuration—the industry standard for duplex patch cord applications. This polarity arrangement simplifies installation and reduces configuration errors in complex network deployments. **Compliance & Safety:** Fully TAA-compliant for government procurement requirements. RoHS/ELV certified to meet environmental regulations. OFNR (Optical Fiber Nonconductive Riser-Rated) jacketing provides fire-safety compliance for in-building use without conduit. **Practical Advantages:** The distinctive pink jacket enhances cable identification in congested data centers and server rooms. Compact 1.8mm diameter facilitates routing through tight cable trays and conduit. Available in custom lengths to accommodate specific installation requirements. Ships from multiple US locations ensuring rapid delivery. **Applications:** Ideal for data center interconnects, telecommunications infrastructure, campus network backbones, and FTTH (Fiber-to-the-Home) deployments. Suitable for both new installations and equipment migrations requiring reliable, tested fiber connectivity. **Support:** Backed by a 90-day limited warranty and free standard shipping on orders exceeding $99.
