The JBX89205 70m SC/ST Duplex Singlemode Fiber Patch Cable represents a premium networking solution for organizations requiring reliable, high-performance optical connectivity. Engineered to industry specifications, this cable delivers the performance characteristics needed for telecommunications infrastructure, data centers, and enterprise networks. CONSTRUCTION & SPECIFICATIONS This duplex patch cable features dual 9/125 singlemode fiber strands with G.657.A1 glass composition, providing excellent bend radius characteristics while maintaining signal integrity over extended distances. The 1.8mm outer diameter jacketing is OFNR riser-rated, enabling safe installation in building riser applications and vertical cable pathways. SC/UPC to ST/UPC connectors are factory-terminated with Type A-B crossover polarity—the industry standard for duplex applications—ensuring immediate deployment without reconfiguration. PERFORMANCE CHARACTERISTICS Attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards, with typical insertion loss of 0.15dB and maximum ≤0.35dB. Return loss exceeds ≥20dB across specified wavelengths (1310nm: 0.25dB/km; 1550nm: 0.35dB/km), ensuring minimal signal reflection and optimal transmission quality. APPLICATIONS & BENEFITS Ideal for connecting telecommunications equipment, network switches, and optical transceivers across medium distances. The 70-meter length accommodates most building layouts without excessive slack or additional terminations. Purple jacket facilitates color-coded network organization, reducing installation errors and simplifying future maintenance. COMPLIANCE & AVAILABILITY Fully RoHS and TAA compliant, meeting government procurement requirements. Available in custom lengths for specialized installations. Ships from multiple US locations with free standard shipping on orders exceeding $99. Supported by comprehensive 90-day limited warranty. This solution combines proven technology with practical features for reliable network infrastructure deployment.
