The JBX67438 OM4 LC/LC Multimode Fiber Optic Cable is engineered for enterprise-level network infrastructure requiring reliable, high-performance fiber connectivity. This 300-meter duplex cable combines advanced OM4 fiber technology with professional-grade construction, making it an ideal choice for data centers, server farms, and large-scale network installations. **Key Features:** OM4 50/125 multimode fiber provides superior bandwidth capabilities compared to OM3, supporting up to 100 Gbps Ethernet over extended distances. The duplex LC/UPC connectors ensure precise alignment and minimal signal loss, while the 18-inch furcated legs offer flexible routing options in crowded patch panel environments. The plenum-rated (OFNP) black jacket is specifically designed for use in air-handling spaces, meeting fire code requirements without additional conduit. **Technical Performance:** With attenuation rates of 3.5 dB/km at 850nm and 1.5 dB/km at 1300nm, this cable delivers consistent, reliable signal transmission. The straight-through polarity configuration ensures straightforward installation and compatibility with standard network equipment. The 5.0mm outside diameter provides optimal balance between flexibility and durability. **Compliance & Quality Assurance:** Manufactured in the USA and fully compliant with ANSI/TIA/EIA-455-171-A standards, this cable meets RoHS/ELV requirements and carries TAA certification, making it eligible for government and enterprise procurement. Each cable is attenuation-tested to ensure consistent quality standards. **Customization & Support:** While this 300m configuration is ready to ship, custom lengths are available to meet specific project requirements. Ships from dual US locations (Danville, CA and Fort Worth, TX) with free standard shipping on orders over $99. All units include a 90-day limited warranty covering manufacturing defects. **Ideal Applications:** Perfect for campus backbone networks, data center interconnects, high-speed multimedia applications, and any installation requiring plenum-rated multimode fiber in extended-distance configurations. The OM4 specification future-proofs your network infrastructure for emerging high-bandwidth requirements.
