The JBX88330 45-meter ST/ST duplex singlemode fiber patch cable represents professional-grade optical connectivity for mission-critical network applications. Built with precision engineering and stringent quality standards, this cable combines reliability with cost-effectiveness for enterprise installations. **Technical Excellence:** Features a 9/125 micron singlemode core with G.657.A1 glass fiber composition, optimized for long-distance signal transmission. Achieves exceptional optical performance with typical insertion loss of 0.15dB and return loss exceeding 20dB, ensuring signal integrity across extended network runs. Tested to ANSI/TIA/EIA-455-171-A standards with documented attenuation performance at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths. **Compliance & Safety:** Fully TAA compliant for government and institutional procurement. RoHS/ELV certified to EU directive 2002/95/EC, eliminating hazardous substances. OFNR riser-rated jacketing meets fire safety requirements for in-building vertical runs without conduit, reducing installation complexity. **Duplex Configuration:** Type A to B crossover polarity enables bidirectional communication on a single cable, streamlining installations and reducing cable management complexity. Two fiber strands support simultaneous transmission and reception for full-duplex protocols. **Practical Benefits:** The 1.8mm outside diameter ensures easy routing through tight spaces and cable trays. 45-meter length accommodates substantial building distances and campus interconnects. Available in custom lengths for specialized requirements. Backed by 90-day limited warranty and backed by free standard shipping on orders over $99. **Ideal Applications:** Data center backbone connectivity, telecommunications facility interconnects, campus network links, disaster recovery systems, and any enterprise requiring reliable singlemode fiber performance over extended distances. Compatible with standard ST/UPC equipped network equipment from leading manufacturers.
