The JBX83079 is a professional-grade 40-meter LC/ST OM2 50/125 multimode fiber patch cable engineered for high-performance data center and telecommunications infrastructure. This duplex fiber optic cable connects legacy and modern networking equipment, supporting applications from voice and data to video transmission. **Technical Excellence:** Built with OM2 50/125 multimode fiber, this cable delivers optimal performance across standard operating wavelengths. Attenuation specifications of 3.5 dB/km at 850 nm and 1.0 dB/km at 1300 nm ensure minimal signal loss over the 40-meter span. Insertion loss testing confirms ≤0.35dB (0.15dB typical) and return loss ≥60dB, meeting stringent industry standards for signal integrity. **Robust Construction:** The bend-insensitive OFNP (Optical Fiber Non-conductive Plenum-rated) jacketing protects against physical stress and accommodates tight cable routing common in modern data centers. The compact 1.8mm outer diameter maximizes rack space efficiency. Type A to B crossover polarity configuration ensures proper duplex operation in most network topologies. **Compliance & Identification:** Fully TAA-compliant for government and enterprise procurement. The distinctive yellow color enables quick visual identification for efficient network management and troubleshooting. RoHS/ELV compliance confirms environmentally responsible manufacturing. **Application-Ready:** Ideal for connecting network switches, routers, patch panels, and fiber optic transceivers in campus networks, data centers, and telecommunications facilities. The 40-meter length addresses mid-to-long-distance interconnections while maintaining signal quality. **Reliability & Support:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Backed by 90-day limited warranty. Available with custom lengths upon request. Ships from multiple US locations with free standard shipping on orders exceeding $99.
