The JBX43577 ST/APC to FC/APC simplex fiber patch cable represents premium quality optical connectivity solutions for demanding networking environments. This 5-meter cable is engineered with precision-aligned 9/125 singlemode fiber core, delivering exceptional performance suitable for telecommunications, data centers, and enterprise network installations. **Superior Performance Specifications:** With insertion loss testing at ≤0.35dB (0.15dB typical) and return loss maintained at ≥20dB, this cable minimizes signal degradation across your network. The attenuation rates of 1310 nm: 0.25 dB/km and 1550 nm: 0.35 dB/km ensure optimal transmission across both C-band and L-band wavelengths. The G.657.A1 glass fiber specification supports modern, bend-resistant applications without compromising signal quality. **Professional-Grade Construction:** The cable features a 1.8mm outside diameter with OFNR (Riser Rated) jacketing, meeting stringent fire safety codes required in commercial buildings. The bright yellow jacket provides excellent visibility and organization in complex cable management scenarios. Manufactured with RoHS/ELV compliance, this cable meets environmental and regulatory requirements across global markets. **Application Versatility:** Ideal for telecommunications infrastructure, network backbone connections, fiber-to-the-premise (FTTP) installations, and data center interconnects. The simplex configuration supports unidirectional signal transmission, making it perfect for applications requiring dedicated transmit or receive paths. **Convenient Purchasing & Support:** Qualify for free standard shipping on orders exceeding $99. Custom lengths are available for unique installation requirements. The 90-day limited warranty provides peace of mind, and TAA compliance ensures government sector purchasing compatibility. Ships from multiple US locations including Danville, CA; Fort Worth, TX; and Beaufort, SC for expedited delivery. **Technical Excellence:** Every cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. The straight-through polarity design eliminates confusion during installation. Whether you're upgrading legacy systems or building new infrastructure, this professional-grade fiber patch cable delivers reliable, future-proof connectivity.
