The JBX43721 SC/APC to LC/UPC simplex fiber patch cable represents professional-grade connectivity for modern network infrastructure. This 9-meter cable is engineered to deliver reliable fiber optic signal transmission in demanding environments ranging from data centers to telecommunications facilities. **Technical Excellence** Featuring 9/125 singlemode fiber core with G.657.A1 glass composition, this cable achieves exceptional performance metrics. The insertion loss of 0.15dB typical (≤0.35dB maximum) and return loss of ≥20dB ensure minimal signal degradation over distance. Attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm comply with industry standards tested per ANSI/TIA/EIA-455-171-A-2001. **Quality Construction** The cable features a robust 1.8mm outer diameter with OFNR (Optical Fiber Non-conductive Riser) rated jacketing, making it suitable for vertical runs in multi-story buildings while meeting fire safety codes. The yellow jacket provides easy identification in cable management scenarios. **Compliance & Standards** TAA compliant and certified under RoHS/ELV directives, this cable meets stringent government procurement requirements. It's manufactured to exacting standards with multiple origin options (Taiwan, US, China) ensuring consistent quality. **Practical Benefits** The straight-through polarity configuration simplifies installation without requiring adapter cables. SC/APC (angled physical contact) connectors on one end and LC/UPC (uncoded) on the other provide flexibility for mixed-connector environments. The simplex design (single fiber strand) is ideal for unidirectional applications or when paired with complementary cables for bidirectional communication. **Value Proposition** Available in custom lengths beyond the standard 9-meter configuration, this cable offers flexibility for unique installation requirements. Free standard shipping on orders exceeding $99 and a 90-day limited warranty provide additional confidence. Ships from multiple US locations (California, Texas, South Carolina) for rapid delivery. **Applications** Ideal for fiber-to-the-desk installations, equipment interconnection, laboratory testing, and telecommunications infrastructure upgrades. Compatible with systems requiring single-mode, long-distance fiber transmission with minimal signal loss.
