The JBX45119 40-meter OM3 SC/SC multimode fiber patch cable represents a professional-grade solution for modern network infrastructure. Built to exacting standards, this duplex cable features industry-standard SC/UPC connectors configured in Type A to B crossover mode, the most widely adopted duplex configuration for enterprise networks. Superior Performance Characteristics: This OM3 50/125 multimode cable delivers outstanding signal quality with insertion loss of just ≤0.35dB (0.15dB typical) and return loss ≥60dB, ensuring minimal signal degradation over longer distances. The cable supports 850nm and 1300nm wavelengths with attenuation ratings of 3.5 dB/km and 1.0 dB/km respectively, making it suitable for high-speed data transmission in data centers, server rooms, and campus networks. Durable Construction: Featuring bend-insensitive fiber technology and OFNP jacketing, the cable accommodates tight bends and frequent repositioning without compromising performance. The slim 1.8mm outer diameter enables efficient cable management and space optimization in congested network environments. The robust plastic accessories and materials ensure longevity in both indoor and outdoor installations. Compliance & Certification: TAA compliant and manufactured to the highest standards, this cable meets all EU RoHS/ELV directives (EU directive 2002/95/EC). Performance testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality and reliability. Ideal Applications: Perfect for connecting network equipment in data centers, telecommunications facilities, enterprise networks, and multimedia installations. The 40-meter length provides flexibility for medium-distance runs without requiring repeaters or signal boosters.
