The JBX88233 12-meter ST/ST duplex singlemode fiber patch cable is a professional-grade networking solution designed for organizations requiring reliable, high-performance fiber optic connectivity. This cable combines cutting-edge fiber technology with practical design features to deliver exceptional value for telecommunications, data center, and enterprise network environments. Key Technical Specifications: Features a robust 9/125 micron singlemode core with G.657.A1 glass fiber construction, engineered specifically for long-distance signal transmission with minimal attenuation. The cable achieves impressive attenuation ratings of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, making it ideal for both traditional and modern network wavelengths. Insertion loss is exceptionally low at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB—specifications that ensure signal integrity over extended distances. Design and Construction: The duplex configuration with Type A to B crossover polarity is specifically optimized for standard duplex patch cord applications. ST/UPC connectors provide secure, industry-standard connections. The compact 1.8mm outer diameter jacket with OFNR (Optical Fiber Non-conductive Riser) rating offers excellent space efficiency while meeting building code requirements for plenum installations and riser applications. Compliance and Standards: TAA (Trade Agreements Act) compliant for government and public sector procurement. Manufactured in accordance with ANSI/TIA/EIA-455-171-A-2001 standards and compliant with RoHS/ELV directives. The cable is available in multiple manufacturing sources (Taiwan, US, and China) ensuring supply chain flexibility. Customization and Availability: While this product is available in the standard 12-meter length, custom lengths are available upon request to accommodate specific installation requirements. Free standard shipping on orders over $99, with fulfillment from strategically located warehouses in California, Texas, and South Carolina. Ideal Applications: Backbone cabling in data centers, telecommunications installations, laboratory environments, and any scenario requiring high-reliability singlemode fiber connectivity. The red color coding ensures easy identification in complex cable management systems.
