The JBX88280 0.5-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic installations. This cable is manufactured to exacting standards, incorporating G.657.A1 grade glass fiber with a precise 9/125 micron core dimension, making it ideal for long-distance signal transmission in telecommunications and data center environments. **Technical Excellence** Each cable undergoes rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. With typical insertion loss of just 0.15dB and maximum 0.35dB, this cable minimizes signal degradation over extended runs. The return loss specification of ≥20dB ensures optimal signal reflection characteristics. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm provide consistent performance across multiple wavelength bands. **Standards Compliance & Safety** TAA compliance makes this cable eligible for federal government procurement, while RoHS/ELV directive compliance ensures environmental responsibility. The riser-rated OFNR jacketing provides essential flame resistance and safety characteristics required in modern building installations. The compact 1.8mm outside diameter enables efficient cable management in crowded pathways. **Practical Features** The ST/UPC to ST/UPC connectors with Type A to B crossover polarity follow industry-standard duplex patch cord configurations, simplifying installation and reducing compatibility issues. The distinctive green jacketing aids in quick identification and organization within complex fiber infrastructures. **Flexibility & Support** While this product provides excellent value at 0.5 meters, custom lengths are available to meet specific installation requirements. Ships from multiple US locations (California, Texas, South Carolina) ensuring rapid delivery, with free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for enterprise deployments. **Ideal Applications** Perfect for telecommunications networks, enterprise data centers, campus area networks (CANs), and metropolitan area networks (MANs) where reliable, low-loss fiber connectivity is essential. Compatible with network equipment featuring ST fiber ports.
