The JBX88227 ST/ST duplex singlemode fiber patch cable represents a high-performance solution for demanding telecommunications and data center environments. This professionally engineered 5-meter cable connects ST-keyed fiber optic connectors with precision-polished UPC terminations, ensuring optimal signal integrity. Key Technical Features: The cable utilizes a 9/125 micrometer singlemode fiber core with G.657.A1 specification, enabling extended transmission distances with minimal signal degradation. Attenuation testing confirms performance at 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, ideal for DWDM and long-haul applications. The duplex configuration (Type A to B crossover) allows simultaneous two-way communication, essential for full-duplex network protocols. Performance Specifications: With typical insertion loss of 0.15dB (maximum 0.35dB) and return loss exceeding 20dB, this cable exceeds ANSI/TIA/EIA standards for signal fidelity. The 1.8mm outer diameter jacketing combines durability with space-efficiency in crowded installations. Compliance & Quality: Fully TAA compliant for government and GSA Schedule purchases. RoHS/ELV directive adherence eliminates hazardous substances. OFNR riser rating permits installation in non-plenum building spaces while maintaining fire safety standards. Applications: Ideal for telecommunications carrier networks, enterprise data centers, ISP backbone infrastructure, and broadcast/media facilities requiring sub-millisecond latency. The red jacket facilitates quick visual identification in multi-cable environments. Custom Solutions: Available in custom lengths beyond 5m for specific deployment requirements. Ships from multiple US locations ensuring rapid delivery. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Warranty & Support: 90-day limited warranty covers manufacturing defects. Compatible with standard ST patch panel systems and network testing equipment.
