The JBX43157 5-meter SC/APC to SC/APC simplex singlemode fiber patch cable represents enterprise-grade connectivity for demanding network environments. Engineered with precision 9/125 G.657.A1 singlemode fiber, this cable delivers exceptional performance for telecommunications, data centers, and telecommunications infrastructure. **Superior Performance Specifications:** This cable achieves exceptional return loss (≥20dB) and insertion loss of just ≤0.35dB maximum, translating to minimal signal degradation. Attenuation measurements of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet ANSI/TIA/EIA standards, ensuring reliable performance across the optical spectrum. **Design & Construction:** The 1.8mm outside diameter provides flexibility without compromising durability. The bright yellow riser-rated (OFNR) jacket offers excellent visibility in crowded conduits while meeting UL fire safety requirements. APC connectors feature angled polishing for superior return loss, critical for high-speed applications. **Compliance & Certifications:** Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets government and enterprise purchasing requirements. All connectors are precision-manufactured with attenuation testing per ANSI/TIA/EIA-455-171-A-2001. **Flexibility & Customization:** While this product ships in standard 5-meter lengths, custom lengths are available to meet specific installation requirements. Choose from multiple US distribution centers in California, Texas, and South Carolina for expedited shipping. **Warranty & Support:** Backed by a 90-day limited warranty ensuring peace of mind. The simplex configuration transmits signals in one direction, making it ideal for unidirectional applications or use with SC/APC duplex systems. **Applications:** Perfect for telecommunications networks, fiber-to-the-home (FTTH) installations, laboratory testing, broadcast facilities, and enterprise data center patch panels.
