The JBX89183 represents professional-grade fiber optic connectivity designed for telecommunications, data centers, and enterprise networks. This 2-meter SC/ST duplex singlemode patch cable combines precision engineering with practical installation features to meet demanding industry standards. **Specifications & Performance:** The 9/125 micrometer core diameter is specifically optimized for single-mode transmission, enabling long-distance signal propagation with minimal modal dispersion. Attenuation performance is outstanding at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), with typical insertion loss of just 0.15dB and return loss exceeding 20dB. These metrics ensure signal integrity across backbone and long-haul connections. **Construction & Durability:** Featuring G.657.A1 grade glass fiber, this cable exhibits enhanced bend radius performance compared to standard G.652.D fiber, allowing for tighter routing in congested installations. The OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance suitable for vertical pathways in buildings, while the 1.8mm diameter profile enables efficient cable management and reduced conduit space requirements. **Compliance & Standards:** TAA (Trade Agreements Act) compliant for U.S. government and institutional buyers. RoHS/ELV certified per EU directive 2002/95/EC. All attenuation measurements conform to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring third-party verified performance. **Application Scenarios:** - Telecom central office interconnects - Data center backbone connectivity - Campus network infrastructure - Government and military installations - Long-distance network links **Practical Advantages:** Custom length options available for unique installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for faster delivery. Free standard shipping on orders exceeding $99. 90-day limited warranty provides confidence in your investment. **Installation Notes:** The Type A to B crossover polarity is standard for duplex patch cords, compatible with most network equipment. SC connectors offer superior return loss performance, while ST connectors provide secure bayonet coupling. Both connector types feature UPC (Ultra Physical Contact) polishing for optimal performance.
