The JBX43496 25-meter ST/APC to ST/UPC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking applications. Built with precision engineering and manufactured to stringent international standards, this cable is ideal for telecommunications carriers, data centers, and enterprise networks requiring robust signal transmission over extended distances. Key Technical Specifications: This singlemode fiber cable features a 9/125 micron core with G.657.A1 glass fiber composition, ensuring optimal performance in bend-sensitive environments. The ST/APC-to-ST/UPC configuration provides industry-standard connectivity with minimal signal loss—just 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Typical insertion loss is only 0.15dB with a maximum of 0.35dB, while return loss exceeds 20dB, guaranteeing exceptional signal quality. Durable Construction: The bright yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance and building code compliance while enabling easy identification in cable infrastructure. The 1.8mm outer diameter fits standard conduit and cable management systems. Compliance & Certification: Fully TAA compliant and RoHS/ELV directive adherent, this cable meets rigorous governmental procurement standards. It's tested according to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reliability and consistency. Applications: Perfect for long-haul telecommunications, enterprise backbone networks, data center interconnects, and premises cabling systems where singlemode performance is essential. Customization & Availability: Available in custom lengths to suit specific installation requirements. Ships from multiple U.S. locations with free standard shipping on orders over $99. 90-day limited warranty included.
