The JBX43509 ST/APC to ST/UPC Simplex Fiber Patch Cable represents a premium solution for telecommunications professionals and network infrastructure specialists. Measuring 90 meters in length, this cable bridges the gap between intermediate network segments with exceptional signal integrity and reliability. **Technical Excellence** This simplex fiber cable utilizes G.657.A1 glass fiber with a precisely engineered 9/125 singlemode core. The geometry ensures optimal performance across critical telecommunications wavelengths, including 1310 nm and 1550 nm bands. Attenuation specifications of 0.25 dB/km and 0.35 dB/km respectively demonstrate this cable's suitability for long-distance deployments. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry benchmarks set by ANSI/TIA/EIA-455-171-A standards. **Industry Compliance** Designed with regulatory compliance as a core principle, this cable meets EU RoHS Directive 2002/95/EC requirements and carries TAA compliance certification, making it suitable for government and enterprise deployments. The riser-rated (OFNR) jacketing classification ensures safe installation in building spaces between floors without additional conduit. **Practical Features** The distinctive yellow jacket provides visual identification crucial in complex network installations, reducing troubleshooting time and installation errors. The 1.8mm outer diameter balances durability with flexibility, accommodating varied installation scenarios. Available in custom lengths beyond the standard 90m specification, this cable adapts to unique network topologies and requirements. **Applications** Ideal for telecommunications rooms, data centers, campus networks, and long-haul optical transmission systems. This cable excels in environments requiring reliable singlemode transmission over moderate to extended distances. The straight-through polarity configuration ensures straightforward installation and compatibility with standard ST connector configurations. **Support and Warranty** Backed by a 90-day limited warranty and available from multiple distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC), this product offers both product assurance and logistics convenience. Free standard shipping on orders exceeding $99 further enhances value for network professionals.
