The JBX67975 20m LC/LC OM4 duplex multimode fiber patch cable represents the pinnacle of performance and reliability for modern data center and enterprise network environments. Specifically engineered to support 100Gbps Ethernet applications, this cable delivers the high-speed connectivity demands of today's bandwidth-intensive operations. **Superior Performance Specifications** With maximum insertion loss of 0.35dB (typical 0.15dB) and return loss exceeding 20dB, this cable ensures minimal signal degradation over its 20-meter length. Testing conducted at both 850nm and 1300nm wavelengths confirms attenuation rates of 3.5dB/km and 1.0dB/km respectively, meeting or exceeding industry standards. All measurements are performed in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistency and reliability. **Advanced Fiber Technology** The OM4 50/125 multimode fiber incorporates bend-insensitive technology that significantly improves cable durability and installation flexibility. This innovation allows tighter bending radiuses without performance compromise, reducing installation complexity in confined spaces and protecting signal integrity throughout the cable's lifecycle. **Connectivity and Compliance** LC/UPC connectors provide secure, low-loss connections typical of professional-grade installations. The Type A to B crossover polarity is optimized for duplex patch cord applications. The cable is TAA (Trade Agreements Act) compliant, making it eligible for government and institutional procurement contracts. RoHS certification and EU directive 2002/95/EC compliance ensure environmental responsibility. **Installation and Maintenance** The slim 1.8mm outer diameter facilitates easy routing through cable management systems and conduit. The riser-rated (OFNR) gray jacket provides flame resistance suitable for indoor building applications. Custom lengths are available for specialized installations. **Ideal Applications** Perfect for data centers, server room installations, campus networks, and enterprise backbone connectivity. Suitable for organizations requiring TAA-compliant network infrastructure, including government agencies and contractors. Backed by a 90-day limited warranty and manufactured to exacting quality standards.
