The JBX88425 ST/ST singlemode fiber patch cable represents enterprise-grade connectivity designed to meet rigorous telecommunications standards. At 70 meters in length, this duplex configuration allows simultaneous bidirectional signal transmission, making it ideal for full-duplex communication systems in data centers, telecommunications networks, and research facilities. Technical Excellence: This cable features 9/125 micrometer core/cladding dimensions optimized for singlemode transmission at 1310nm and 1550nm wavelengths. The G.657.A1 glass fiber specification ensures minimal chromatic dispersion and modal dispersion, critical for long-distance, high-speed data transmission. Attenuation performance is exceptional at 0.25dB/km (1310nm) or 0.35dB/km (1550nm), enabling reliable communication over extended distances. TAA Compliance and Standards: As a TAA (Trade Agreements Act) compliant product, this cable meets U.S. government procurement requirements, making it suitable for federal contracts and public sector deployments. The cable conforms to EU RoHS directives and undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality. Design and Safety Features: The 1.8mm outside diameter provides flexibility for routing through cable trays and conduit systems. OFNR (Optical Fiber Non-conductive Riser) rating ensures fire safety compliance for vertical installations in multi-story buildings. The distinctive pink jacket distinguishes this cable in color-coded network environments, reducing installation errors and improving troubleshooting efficiency. Connector Configuration: ST/UPC (Ultra Physical Contact) connectors with Type A to B crossover polarity represent the industry standard for duplex patch cord applications. This configuration maximizes signal fidelity with return loss ≥20dB, minimizing reflections that could degrade transmission quality. Customization and Support: Custom lengths are available upon request, accommodating unique network architectures and installation requirements. The 90-day limited warranty provides peace of mind for mission-critical applications. Free standard shipping on orders exceeding $99 makes bulk procurement economical. Applications: Ideal for telecommunications hub connections, data center interconnects, fiber optic network expansions, and laboratory testing environments requiring reliable singlemode connectivity.
