The JBX43204 65-meter LC/APC to FC/UPC simplex singlemode fiber patch cable represents a premium solution for telecommunications professionals and network infrastructure specialists. This meticulously engineered fiber optic cable is designed to meet the rigorous demands of modern data centers, telecommunications facilities, and enterprise network environments. **Technical Excellence** Constructed with a 9/125 micrometer singlemode core and G.657.A1 glass fiber, this cable delivers exceptional optical performance. The LC/APC (Angle Physical Contact) to FC/UPC (Ultra Physical Contact) connector configuration ensures superior coupling and minimal signal degradation. Tested insertion loss of ≤0.35dB (with typical performance of 0.15dB) and return loss of ≥20dB exceed industry standards, while attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm provide predictable, reliable signal transmission. **Professional Features** The distinctive yellow jacketing improves cable identification in complex installations, while 1.8mm outside diameter allows for efficient cable management. Riser-rated (OFNR) construction ensures full compliance with building codes and fire safety regulations. The straight-through polarity configuration supports standard telecommunications protocols. **Compliance & Standards** TAA compliant certification meets U.S. government procurement requirements. RoHS/ELV compliance demonstrates environmental responsibility. Manufacturing to ANSI/TIA/EIA-455-171-A standards guarantees consistent quality and performance. **Flexibility & Service** Available in custom lengths beyond the standard 65-meter specification, accommodating unique installation requirements. Shipped from U.S. distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC) ensures rapid delivery. Free standard shipping on orders exceeding $99 provides exceptional value. Backed by a comprehensive 90-day limited warranty. **Applications** Ideal for telecommunications networks, fiber-to-the-premises (FTTP) installations, data center interconnects, laboratory instrumentation, and any application requiring reliable singlemode fiber signal transmission. The simplex configuration suits point-to-point communications and unidirectional signal paths. Choose the JBX43204 for professional-grade fiber connectivity that combines performance, reliability, and compliance in every installation.
