The JBX43552 ST/APC to FC/UPC fiber patch cable represents professional-grade connectivity designed for mission-critical fiber optic networks. At 10 meters in length, this simplex configuration delivers reliable single-direction signal transmission, making it ideal for point-to-point connections in telecommunications infrastructure, data centers, and enterprise networks. **Technical Excellence:** Constructed with G.657.A1 grade singlemode glass fiber, this cable features a 9/125 micrometer core/cladding configuration, the industry standard for long-distance, low-loss signal transmission. The cable has been rigorously tested and certified to meet ANSI/TIA/EIA-455-171-A specifications, delivering consistent performance with insertion loss ≤0.35dB (typical 0.15dB) and return loss ≥20dB. **Superior Build Quality:** The 1.8mm outer diameter plastic jacketing is OFNR riser-rated, ensuring compliance with building codes and safety requirements for installation in vertical cable runs. The yellow jacket provides superior visibility in dense cable environments, reducing installation errors and simplifying future maintenance and upgrades. **Compliance & Reliability:** Full TAA compliance makes this cable suitable for government and institutional procurement. RoHS/ELV directive compliance ensures environmental responsibility. The 90-day limited warranty protects your investment, while the cable's construction supports straight-through polarity transmission across standard 1310nm and 1550nm wavelengths used in telecommunications. **Practical Applications:** Perfect for connecting optical transceivers, fiber switches, network interface cards, and telecommunications equipment. The ST/APC and FC/UPC connector combination accommodates diverse network architectures and legacy system integration. **Ordering Flexibility:** While this listing features the standard 10-meter configuration, custom lengths are available to accommodate specific installation requirements. Free standard shipping on orders exceeding $99, with rapid fulfillment from multiple distribution centers.
