The JBX88270 45m ST/ST duplex singlemode fiber patch cable represents the gold standard in optical connectivity solutions for telecommunications and data center environments. This high-performance cable is specifically engineered for organizations requiring reliable, long-distance signal transmission with minimal attenuation and maximum data integrity. Key Technical Features: Construction: 9/125 singlemode fiber core with G.657.A1 grade glass provides superior bend radius performance while maintaining traditional singlemode characteristics. The duplex configuration includes two independent strands, allowing simultaneous bi-directional communication. The 1.8mm outside diameter with riser-rated (OFNR) jacketing ensures safe installation in plenum spaces and building structures. Optical Performance: This cable excels in low-loss applications with insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring minimal signal degradation over the 45-meter span. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make it ideal for both short-wavelength and long-wavelength applications. Compliance & Quality: Full TAA compliance certifies this cable for government and federal procurement. RoHS/ELV compliance ensures environmental safety. Rigorous ANSI/TIA/EIA-455-171-A testing validates performance under real-world conditions. Manufacturing from Taiwan, US, and Chinese facilities ensures quality consistency and supply chain reliability. Applications: Perfect for campus backbone networks, long-distance building-to-building connections, data center high-density patching, telecommunications infrastructure, and any application requiring maximum performance over extended distances. The ST/UPC connectors provide industry-standard mechanical durability with repeatable mating cycles. Customization & Availability: Custom lengths are available for unique installation requirements. Free standard shipping applies to orders over $99, with distribution from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. The 90-day limited warranty provides peace of mind on your network investment. Whether upgrading legacy infrastructure or building new high-performance networks, this TAA-compliant singlemode patch cable delivers the reliability and performance data center professionals demand.
