The JBX45143 12-meter OM3 SC/SC multimode fiber patch cable represents a premium solution for modern network infrastructure requiring reliable, high-speed optical connectivity. Manufactured to stringent international standards, this professional-grade cable delivers consistent performance in demanding data center, telecommunications, and enterprise environments. **Technical Specifications:** This cable features OM3 50/125 multimode fiber core specifically engineered to support 10 Gigabit Ethernet at distances up to 300 meters. The dual SC/UPC connectors utilize Type A to B crossover polarity configuration, the industry standard for duplex patch cords. With an outer diameter of just 1.8mm, the cable maintains exceptional flexibility without compromising signal integrity. **Superior Performance Characteristics:** Testing per ANSI/TIA/EIA-455-171-A-2001 standards confirms exceptional performance metrics: insertion loss of ≤0.35dB (typical 0.15dB), return loss exceeding 60dB, and attenuation ratings of 3.5 dB/km at 850nm or 1.0 dB/km at 1300nm. These specifications ensure minimal signal degradation and maximum data transmission efficiency. **Advanced Jacketing Technology:** The bend-insensitive OFNP (Plenum-rated) jacketing provides superior durability while maintaining compliance with fire safety codes. This innovative design allows for tighter bend radius installations without signal loss—a critical advantage in congested patch panel environments. **Compliance & Certification:** ✓ TAA (Trade Agreements Act) Compliant - Approved for government and federal procurement ✓ RoHS/ELV Certified - Environmentally responsible manufacturing ✓ Multiple manufacturing facilities across TW, US, and CN for supply chain reliability **Applications:** Ideal for: Data center interconnections, network backbone cabling, telecommunications facilities, enterprise IT infrastructure, and high-bandwidth multimedia transmission. **Custom Solutions Available:** Requiring a different cable length?
