The JBX67985 70m LC/LC OM4 duplex multimode fiber patch cable represents professional-grade infrastructure cabling designed for the most demanding network environments. Whether deploying 100GB network speeds, upgrading existing data center facilities, or establishing new telecommunications infrastructure, this cable delivers exceptional performance and reliability. **Superior Performance Specifications:** Constructed with OM4 50/125 multimode optical fiber, this cable supports both 850nm and 1300nm wavelengths, offering exceptional versatility across multiple network standards. The impressive attenuation specifications (3.5 dB/km at 850nm, 1.0 dB/km at 1300nm) enable efficient long-distance transmission. With typical insertion loss of just 0.15dB and return loss exceeding 20dB, signal integrity remains pristine across the entire 70-meter span. **Advanced Cable Construction:** The bend-insensitive fiber technology significantly reduces installation labor and minimizes signal degradation caused by tight bends during cable runs. The duplex configuration with Type A to B crossover polarity ensures proper signal transmission for standard network configurations. Riser-rated (OFNR) jacketing provides fire-safe operation in building environments while the compact 1.8mm diameter facilitates efficient cable management. **Compliance & Certification:** TAA compliance ensures this cable meets government procurement standards, making it ideal for federal contracts and regulated environments. Full RoHS/ELV compliance demonstrates environmental responsibility. Independent testing validates conformance to ANSI/TIA/EIA-455-171-A standards, guaranteeing performance consistency. **Practical Applications:** Ideal for data center interconnects, server-to-switch connections, equipment upgrades, and backbone infrastructure. The 70-meter length accommodates facilities with significant distances between network equipment. Custom lengths are available for specialized deployments. **Reliability & Support:** Each cable ships from strategically located U.S. and international warehouses for rapid delivery. The 90-day limited warranty provides added peace of mind. Free standard shipping on orders over $99 reduces deployment costs. These cables are manufactured to rigorous quality standards, ensuring years of trouble-free operation in production environments.
