The JBX68605 20-meter OM4 LC/SC duplex multimode fiber patch cable represents the gold standard for modern high-speed network infrastructure. Specifically designed to support 100GB Ethernet applications, this cable delivers the performance, reliability, and compliance standards required by data centers, telecommunications facilities, and enterprise networks. **Technical Specifications & Performance** Built with OM4 50/125 multimode fiber featuring bend-insensitive technology, this cable minimizes signal degradation during installation and provides exceptional durability in tight spaces. The duplex configuration includes two fiber strands arranged in Type A to B crossover polarity—the most common and practical configuration for standard network deployments. Insertion loss measurements of ≤0.35dB (with typical performance of 0.15dB) ensure minimal signal attenuation, while return loss exceeding 60dB guarantees excellent signal quality. The cable supports dual-wavelength operation at 850nm (3.5dB/km) and 1300nm (1.0dB/km), providing flexibility for various network architectures. **Design & Construction Quality** The compact 1.8mm outer diameter reduces clutter in cable trays and conduits while maintaining structural integrity. Plenum-rated OFNP (Optical Fiber Non-conductive Plenum) jacketing ensures safe use in air-handling spaces, meeting critical fire codes and safety standards. The green jacket provides instant visual identification in multi-cable environments, streamlining troubleshooting and maintenance. LC/UPC to SC/UPC connectors offer industry-standard connectivity with minimal back-reflection, ensuring clean, reliable connections in patch panels and equipment ports. **Compliance & Reliability** TAA compliance makes this cable ideal for government contracts, educational institutions, and regulated industries. Full RoHS/ELV directive compliance demonstrates commitment to environmental responsibility without compromising performance. The 90-day limited warranty provides protection for your investment, backed by quality testing in accordance with ANSI/TIA/EIA standards. **Applications & Use Cases** - Data center backbone connections - High-speed network switch interconnects - 100GB Ethernet deployments - Telecommunications facilities - Government and institutional networks - Enterprise network upgrades **Why Choose This Cable** Unlike economy alternatives, this cable combines professional-grade performance with practical features. Bend-insensitive fiber technology prevents costly installation damage, while plenum rating eliminates the need for conduit in many applications. TAA compliance opens doors to restricted procurement channels, and custom length availability ensures perfect fit for any deployment. **Shipping & Availability** Enjoy free standard shipping on orders exceeding $99, with fulfillment from strategically located distribution centers (Danville CA, Fort Worth TX, Beaufort SC) ensuring fast delivery nationwide. Custom lengths are available for large-scale deployments requiring standardized cable specifications.
