The JBX88276 75-meter ST/ST duplex singlemode fiber patch cable is engineered for demanding telecommunications and data center applications requiring long-distance, high-bandwidth signal transmission. This professional-grade optical cable combines precision engineering with stringent quality standards to deliver exceptional performance. **Key Features & Specifications:** With a 9/125 micron core size, this singlemode fiber cable excels at transmitting data over extended distances with minimal attenuation. The cable achieves an impressive insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring signal integrity across both 1310nm and 1550nm wavelengths—standard for telecommunications infrastructure. The duplex configuration enables simultaneous bidirectional communication, while ST/UPC connectors in Type A to B crossover polarity represent the most common duplex patch cord configuration. **Construction & Durability:** Constructed with G.657.A1 glass fiber and housed in riser-rated (OFNR) jacketing, this cable meets critical fire safety standards while maintaining flexibility for installation. The 1.8mm outside diameter fits standard cable trays and conduit systems. All components comply with RoHS and EU directive 2002/95/EC regulations. **Industry Compliance:** TAA-compliant certification ensures this cable meets government procurement requirements. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliable performance in mission-critical environments. **Applications:** Ideal for telecommunications networks, data centers, ISP backbones, and enterprise LANs requiring dependable long-distance connectivity. The 75-meter length accommodates larger facility spans while maintaining signal quality. Custom lengths available for specialized installations. **Warranty & Support:** Backed by a 90-day limited warranty. Free standard shipping on orders exceeding $99, with multiple U.S. fulfillment locations ensuring rapid delivery.
