The JBX88366 75-meter ST/ST duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring reliable, long-distance fiber optic connectivity. Designed to meet stringent telecommunications standards, this cable delivers exceptional performance for mission-critical applications in data centers, telecommunications facilities, and enterprise networks. **Technical Specifications & Performance:** This cable features a 9/125 micron singlemode fiber core constructed with G.657.A1 grade glass, providing superior performance characteristics. The duplex configuration includes two strands with Type A to B crossover polarity—the industry standard for patch cord applications. Attenuation is exceptionally low at 0.25 dB/km (1310nm) and 0.35 dB/km (1550nm), ensuring minimal signal degradation across the 75-meter span. Insertion loss measures ≤0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB, guaranteeing signal integrity. **Construction & Compliance:** The cable's 1.8mm outside diameter and plastic accessories ensure durability without excessive bulk. The OFNR (Optical Fiber Nonconductive Riser) rating permits installation in vertical cable pathways and between floors without conduit, simplifying network infrastructure deployment. Full RoHS/ELV compliance and TAA certification make this cable suitable for government contracts and institutional procurement processes. **Applications & Use Cases:** Ideal for telecommunications providers, ISPs, enterprise IT departments, and colocation facilities requiring backbone connectivity. The 75-meter length accommodates campus-wide installations, building-to-building links, and data center equipment interconnections. The cable's low attenuation makes it particularly valuable for long-distance signal transmission where signal quality cannot be compromised. **Reliability & Support:** All cables are attenuation-tested per ANSI/TIA/EIA-455-171-A standards before shipment. The 90-day limited warranty provides peace of mind, while custom length options accommodate specific installation requirements. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99.
