The JBX45256 4m SC/SC OM3 50/125 multimode fiber patch cable represents a professional-grade connectivity solution for modern network infrastructures. This versatile cable is engineered to meet the demanding requirements of data centers, telecommunications facilities, and enterprise-level networking environments. **Technical Specifications & Performance:** This duplex fiber patch cable features OM3 50/125 multimode fiber core specifically designed for high-speed data transmission. With an outer diameter of just 1.8mm, the compact profile simplifies cable management in crowded equipment racks. The cable delivers exceptional performance metrics: insertion loss of ≤0.35dB (0.15dB typical), return loss of ≥60dB, and attenuation rates of 3.5 dB/km at 850nm or 1.0 dB/km at 1300nm. All performance testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistency and reliability. **Superior Durability & Protection:** The bend-insensitive OFNP (Optical Fiber Non-Conductive Plenum) jacketing provides exceptional durability while reducing signal degradation caused by cable bending. This advanced jacketing technology protects the fiber core from physical stress, extending cable lifespan in high-traffic installation environments. **Compliance & Environmental Responsibility:** Fully TAA-compliant and certified under RoHS and EU directive 2002/95/EC standards, this cable meets government procurement requirements and environmental regulations. Manufactured with eco-conscious processes across multiple facilities (Taiwan, US, and China), ensuring quality control and supply chain reliability. **Practical Applications:** Ideal for high-speed LAN interconnects, data center backbone connections, server-to-switch communications, and telecommunications networks. The distinctive purple jacket simplifies network organization and troubleshooting in complex cabling systems. **Shipping & Support:** Enjoy free standard shipping on orders over $99 from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for fast delivery. Backed by a 90-day limited warranty and available in custom lengths for specialized requirements.
