The JBX45239 40m OM3 SC/SC multimode fiber patch cable represents an excellent choice for organizations requiring reliable, standards-compliant fiber connectivity solutions. Engineered to deliver superior performance across high-speed data center and campus network environments, this cable combines advanced fiber technology with practical design features that simplify installation and maintenance. Key Performance Specifications: This duplex patch cable utilizes OM3 50/125 multimode fiber with attenuation rates of 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm. The ultra-low insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation over the full 40-meter span. With return loss exceeding 60dB, the cable maintains excellent signal integrity for both voice and data transmission applications. Advanced Design Features: The bend-insensitive fiber technology allows for tighter routing radius compared to conventional multimode fibers, enabling deployment in space-constrained environments without performance compromise. The OFNP jacketing provides superior flame resistance and reduced smoke generation, meeting the highest fire safety standards for indoor installations. The SC/UPC connectors deliver consistent, repeatable connections with Type A to B crossover polarity, the industry standard for duplex patch cord applications. Compliance & Certification: TAA (Trade Agreements Act) compliant with full RoHS/ELV directive adherence, making this cable suitable for government, military, and enterprise procurement programs. Testing performed per ANSI/TIA/EIA-455-171-A standards ensures reliability and performance consistency. The cable is manufactured with quality oversight across multiple facilities (Taiwan, US, China) and backed by a comprehensive 90-day limited warranty. Ideal Applications: Perfect for data center infrastructure, enterprise campus networks, server-to-switch connections, and any high-performance network environment requiring certified multimode fiber connectivity. Available in custom lengths for specific project requirements.
