The JBX91015 20-meter LC/LC duplex singlemode fiber patch cable represents a superior networking solution for organizations requiring dependable, high-performance fiber optic connectivity. This professional-grade cable is constructed with precision-engineered 9/125 singlemode fiber cores, specifically designed to support long-distance, high-bandwidth data transmission with exceptional signal integrity. Key Features & Specifications: This dual-strand duplex configuration provides simultaneous bidirectional communication, making it ideal for full-duplex network applications. The LC/UPC connectors ensure low insertion loss and excellent return loss performance, while the Type A to B crossover polarity configuration is the industry standard for patch cord applications. The cable's attenuation performance is rigorously tested to ANSI/TIA/EIA-455-171-A standards, delivering 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm—well within enterprise specifications. Construction & Durability: The green OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance and safety compliance for building installations. The compact 1.8mm outer diameter allows flexible routing through conduit and cable trays without excessive bulk. The cable's plastic accessory components ensure non-conductive operation and environmental compatibility. Compliance & Standards: TAA (Trade Agreements Act) compliant for U.S. government procurement, RoHS and ELV certified, ensuring environmental responsibility and regulatory compliance. The 90-day limited warranty provides peace-of-mind protection. Applications: Ideal for data centers, telecommunications facilities, enterprise campus networks, server room installations, and any application requiring reliable singlemode fiber connectivity over moderate distances.
