The JBX88200 ST/ST duplex singlemode fiber patch cable represents a professional-grade solution for mission-critical network applications requiring exceptional optical performance and regulatory compliance. This 8-meter cable is engineered with 9/125 singlemode fiber core and G.657.A1 glass composition, delivering ultra-low attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm wavelengths. **Key Performance Features:** With measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable exceeds ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing. The ST/UPC connectors ensure reliable connections with minimal signal degradation, while the Type A to B crossover polarity configuration accommodates most duplex patch cord installations. **Compliance & Safety:** TAA (Trade Agreements Act) compliant for federal procurement requirements, this cable also meets RoHS/ELV directives under EU 2002/95/EC standards. The OFNR (Optical Fiber Non-Conductive Riser) jacket rating permits installation within building risers and plenum spaces where fire safety codes require non-conductive materials. **Design & Durability:** The distinctive yellow jacket enables quick identification and organization in complex network installations. With a compact 1.8mm outside diameter and riser-rated construction, it installs easily in crowded cable trays and conduit systems. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for faster delivery. **Versatile Applications:** Ideal for telecommunications networks, data center interconnects, enterprise backbones, and single-mode fiber signal transmission. Custom lengths available for specialized installation requirements. Backed by 90-day limited warranty and free standard shipping on orders exceeding $99. Manufactured to the highest standards with international quality control (production in Taiwan, US, and China).
