The JBX91013 12-meter LC/LC duplex singlemode fiber patch cable represents professional-grade telecommunications infrastructure. Designed for demanding network environments, this cable delivers reliable signal transmission across extended distances without signal degradation. **Technical Specifications:** The cable features a 9/125 micron singlemode fiber core, the industry standard for long-distance, single-wavelength signal transmission. Each of the two strands (duplex configuration) is terminated with LC/UPC connectors, offering superior polish quality and low return loss. The Type A to B crossover polarity enables straightforward duplex communication without additional components. Attenuation performance is rigorously tested: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, complying with ANSI/TIA/EIA-455-171-A-2001 standards. These specifications ensure minimal signal loss over the full 12-meter run. **Construction & Compliance:** The 1.8mm outer diameter jacket is OFNR riser-rated (Optical Fiber Non-conductive Riser), meeting fire safety codes for in-building installations without conduit. The green PVC jacket provides easy identification and visibility in dense cable environments. TAA (Trade Agreements Act) compliance and RoHS/ELV certification ensure suitability for government contracts, federal projects, and environmentally-conscious procurement. **Applications:** Ideal for data centers, telecommunications closets, server room interconnections, and enterprise network expansions. The singlemode specification suits applications requiring longer distances or higher bandwidth density compared to multimode alternatives. **Flexibility & Support:** Custom lengths available for non-standard installations. Manufactured in Taiwan, United States, or China with consistent quality standards. Ships free on orders exceeding $99 from strategically positioned fulfillment centers in California, Texas, and South Carolina. Backed by a 90-day limited warranty ensuring confidence in your network investment. Choose the JBX91013 for superior fiber optic connectivity that meets stringent industry standards and procurement requirements.
