The JBX42196 25-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Designed for telecommunications, data centers, and enterprise networking applications, this cable delivers exceptional performance characteristics that exceed industry standards. **Superior Performance Specifications:** This singlemode cable features a 9/125 micron core with G.657.A1 glass fiber technology, enabling single-mode propagation that minimizes modal dispersion and maximizes transmission distance. The exceptional insertion loss rating of ≤0.35dB (0.15dB typical) ensures signal strength preservation, while return loss exceeding 20dB prevents signal reflections that degrade performance. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet ANSI/TIA/EIA standards. **Compliance and Standards:** TAA compliance ensures this cable meets Buy American requirements for government and defense projects. RoHS and ELV directive compliance demonstrates our commitment to environmental responsibility. OFNR riser-rated jacketing provides critical fire safety for vertical cable runs in multi-story buildings. **Practical Applications:** Ideal for connecting LC/APC and FC/UPC equipped components in diverse environments including carrier networks, telecommunications closets, laboratory equipment, and long-distance signal transmission. The 1.8mm outside diameter ensures compatibility with standard cable management systems. **Reliability and Support:** Every cable undergoes rigorous attenuation testing per ANSI standards. Backed by a 90-day limited warranty and available in custom lengths for specialized requirements. Ships from strategically located US facilities ensuring rapid delivery with free standard shipping on qualifying orders.
