The JBX43276 LC/APC to ST/APC singlemode fiber patch cable represents a premium solution for fiber optic connectivity in demanding network environments. This 4-meter cable combines precision engineering with reliable performance, making it an excellent choice for IT professionals, systems integrators, and network administrators. **Technical Excellence:** Manufactured with a 9/125 micron singlemode core and G.657.A1 grade glass fiber, this cable meets stringent optical performance standards. The low insertion loss rating of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the return loss specification of ≥20dB guarantees signal integrity. All cables undergo rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm and 1550nm wavelengths. **Compliance & Safety:** TAA compliance ensures this cable meets Buy American Act requirements, making it suitable for government contracts and federal installations. The riser-rated (OFNR) jacketing provides fire-safety protection for in-building applications, while RoHS/ELV compliance reflects environmental responsibility. Manufacturing in the US, Taiwan, and China ensures quality control and supply chain reliability. **Practical Features:** The distinctive yellow outer jacket facilitates quick identification and organization in complex installations. The 1.8mm outside diameter balances flexibility with durability, reducing installation time while maintaining structural integrity. The simplex configuration provides direct point-to-point connectivity ideal for unidirectional applications. **Flexibility & Support:** While this cable is pre-configured at 4 meters, custom length options are available for unique project requirements. Ships from multiple US locations (Danville CA, Fort Worth TX, and Beaufort SC) for faster delivery. Free standard shipping on orders over $99 reduces total project costs. **Applications:** Perfect for data center interconnections, telecommunications infrastructure, fiber-to-the-premises installations, campus network upgrades, and equipment upgrades requiring singlemode connectivity. The straight-through polarity supports standard LC/APC to ST/APC configurations. Backed by a 90-day limited warranty, this cable represents a reliable investment in network infrastructure. Whether upgrading existing systems or building new installations, the JBX43276 delivers consistent, dependable fiber optic performance.
