The JBX43529 ST/APC to ST/APC simplex singlemode fiber patch cable represents a premium solution for professional networking environments requiring dependable, long-distance fiber connectivity. With a 40-meter length, this cable is engineered to bridge significant distances while maintaining signal integrity and minimizing signal degradation. **Superior Technical Performance:** Constructed with a 9/125 singlemode fiber core conforming to ITU-T G.657.A1 standards, this cable delivers exceptional performance across standard telecom wavelengths. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal loss, while the return loss of ≥20dB provides excellent optical isolation. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet or exceed industry standards, making this cable suitable for both legacy and modern fiber-optic applications. **Installation and Identification:** The distinctive yellow jacket serves multiple purposes: it provides excellent visibility during installation, simplifies network documentation, and aids in quick identification during maintenance. The 1.8mm outer diameter enables flexible routing through cable trays and conduit while maintaining durability. The OFNR (Optical Fiber Non-Conductive Riser) rating ensures safe installation in vertical runs and plenum areas within building structures. **Compliance and Standards:** TAA compliance makes this cable suitable for government contracts and institutional procurement programs. RoHS and ELV directive compliance ensure environmental responsibility and support modern sustainability initiatives. The cable is manufactured to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality and performance. **Ideal Applications:** • Data center interconnections • Telecommunications network expansions • Long-distance point-to-point links • Enterprise backbone networks • Metro area networks (MANs) • High-speed data transmission **Custom Options Available:** While the standard 40m length accommodates most installations, custom lengths are available to meet specific project requirements. Ships from multiple US locations for rapid delivery. Free standard shipping applies to orders exceeding $99, reducing overall project costs. **Warranty and Support:** Backed by a 90-day limited warranty, this cable provides peace of mind and reliable customer support for installation and troubleshooting.
