The JBX42653 SC/APC to LC/UPC duplex singlemode fiber patch cable is engineered for demanding telecommunications and data center environments. This 60-meter cable combines superior optical performance with robust construction, making it ideal for long-distance signal transmission. **Technical Specifications:** The cable features 9/125 singlemode fiber with G.657.A1 glass composition, ensuring minimal signal loss and bend-insensitivity. Insertion loss is measured at ≤0.35dB (typical 0.15dB) with return loss ≥20dB, meeting ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation rates are 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, supporting both C-band and L-band wavelengths. **Key Features:** The distinctive yellow jacket enhances cable identification and management in complex installations. Type A to B crossover polarity is standard for duplex patch cords, ensuring proper connectivity. The 1.8mm outside diameter provides flexibility while maintaining durability. OFNR riser-rated jacketing supports vertical runs in buildings, offering fire-safety compliance. **Compliance & Certification:** TAA compliant for government procurement and RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets stringent regulatory requirements. The cable is manufactured to consistent quality standards across multiple production facilities. **Applications:** Ideal for telecommunications networks, enterprise data centers, campus networks, and long-distance signal transmission. The 60-meter length bridges significant distances without signal degradation. Custom lengths are available for specialized requirements. **Warranty & Support:** Backed by a 90-day limited warranty. Free standard shipping on orders exceeding $99, with convenient fulfillment from multiple U.S. locations.
