The JBX45166 4m SC/SC OM3 50/125 multimode fiber patch cable is engineered for professionals who demand reliability and performance. Built to stringent industry standards, this cable delivers exceptional signal transmission for high-speed network communications and data center applications. **Technical Excellence** Featuring OM3 50/125 multimode fiber, this cable supports bandwidth-intensive applications with minimal signal degradation. The bend-insensitive fiber technology ensures durability in tight installations without compromising performance. With insertion loss as low as 0.15dB typical (≤0.35dB maximum) and return loss exceeding 60dB, this cable maintains signal integrity across extended runs. **Design & Construction** The cable utilizes SC/UPC connectors configured in Type A to B crossover polarity—the industry standard for duplex patch cord applications. The OFNP-rated bend-insensitive jacketing with 1.8mm outer diameter provides flexibility and protection in congested cable trays and conduits. The distinctive green color facilitates quick identification and organization in complex network environments. **Compliance & Standards** Fully TAA compliant and manufactured to meet RoHS and EU directive 2002/95/EC requirements, this cable satisfies regulatory requirements for government and enterprise procurement. Performance testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and reliability. **Applications** Ideal for data center interconnects, campus backbone networks, telecommunications installations, and high-speed LAN connections. The 4-meter length provides optimal flexibility for standard server-to-switch distances without excess cable management complexity. **Specifications Summary** • Length: 4 meters • Fiber Type: OM3 50/125 multimode • Connectors: SC/UPC to SC/UPC • Attenuation: 850nm: 3.5 dB/km; 1300nm: 1.0 dB/km • Insertion Loss: ≤0.35dB (0.15dB typical) • Return Loss: ≥60dB • Jacket: OFNP bend-insensitive • Warranty: 90 days limited Available in custom lengths to meet specific installation requirements.
