The JBX42654 SC/APC to LC/UPC 65-meter duplex singlemode fiber patch cable represents a premium solution for mission-critical fiber optic network installations. Specifically engineered for long-distance signal transmission, this cable combines advanced optical performance with robust physical construction to meet the demands of modern telecommunications infrastructure. **Key Specifications & Performance:** This duplex fiber patch cable features two singlemode fiber strands with 9/125 micron core dimensions, optimized for 1310nm and 1550nm wavelengths. The G.657.A1 specification ensures superior bend performance while maintaining excellent attenuation characteristics (0.25dB/km at 1310nm and 0.35dB/km at 1550nm). Insertion loss testing meets ANSI/TIA/EIA standards with typical loss of 0.15dB and maximum 0.35dB, while return loss exceeds 20dB for optimal signal integrity. **Build Quality & Compliance:** Constructed with plastic accessories and OFNR riser-rated jacketing, this cable is suitable for vertical runs in building infrastructure. The yellow jacket provides superior visibility in dense cable environments. TAA compliance and RoHS/ELV certification make this ideal for government and enterprise procurement requirements. **Practical Applications:** Perfect for data center interconnections, telecommunications installations, long-haul network extensions, and carrier-grade applications. The 65-meter length accommodates substantial distances while maintaining signal integrity. Available in custom lengths for specialized deployment scenarios. **Reliability & Support:** Backed by a 90-day limited warranty and supported by multiple fulfillment locations (Danville CA, Fort Worth TX, Beaufort SC) enabling fast delivery. Free standard shipping on orders exceeding $99 provides excellent value for bulk installations. Professional-grade performance at competitive pricing.
