The JBX88323 12-meter ST/ST duplex singlemode fiber patch cable represents a professional-grade solution for telecommunications and data center infrastructure. Manufactured to exacting standards, this cable delivers exceptional optical performance critical for high-speed network environments. **Technical Excellence** Features a 9/125 micrometer singlemode fiber core constructed from G.657.A1 grade glass, optimized for both 1310nm and 1550nm wavelengths. Attenuation performance of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensures minimal signal degradation over the 12-meter span. Low insertion loss (≤0.35dB typical 0.15dB) and high return loss (≥20dB) ratings guarantee reliable signal integrity and reduced reflectance, critical for preventing network errors and data loss. **Compliance & Safety** Fully TAA compliant for government and institutional procurement. Meets RoHS/ELV directives and EU 2002/95/EC environmental standards. The OFNR (Optical Fiber Non-conductive Riser) rated jacket provides essential fire safety compliance for vertical cable runs in commercial buildings. **Practical Design** ST/UPC connectors with Type A to B crossover polarity (standard for duplex patch cords) ensure plug-and-play compatibility with existing ST infrastructure. The streamlined 1.8mm diameter jacket facilitates easy routing through cable trays and conduit systems. Custom length options available for non-standard applications. **Reliability & Support** 90-day limited warranty provides peace of mind. Tested in accordance with ANSI/TIA/EIA-455-171-A standards ensuring consistent quality. Multiple U.S. fulfillment locations enable fast shipping with free standard delivery on orders exceeding $99. **Applications** Ideal for enterprise data centers, telecommunications networks, long-distance backbone connections, and high-performance computing facilities requiring single-mode precision. Perfect for organizations requiring TAA compliance for government contracting.
