The JBX65508 OM4 Micro Armored Fiber Cable represents a premium solution for organizations requiring robust, high-performance multimode fiber connectivity. This 50-meter cable is engineered to meet the demanding requirements of modern data centers and enterprise networks, combining superior optical performance with exceptional mechanical durability. **Key Performance Features:** This cable delivers exceptional transmission characteristics with insertion loss testing at ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring minimal signal degradation over longer runs. The OM4 50/125 multimode fiber core offers optimized performance at both 850nm and 1300nm wavelengths, with attenuation rates of 3.5dB/km at 850nm and 1.5dB/km at 1300nm. The bend-insensitive fiber technology accommodates installation constraints without compromising performance. **Durability & Protection:** The 3.0mm micro-armored jacket provides substantial mechanical protection against crushing, abrasion, and impact while maintaining installation flexibility. The plastic jacketing is plenum-rated (OFNP), making it suitable for air-handling spaces and critical infrastructure environments. Dual LC/UPC connectors feature straight-through polarity for seamless integration with standard networking equipment. **Installation Excellence:** The 18-inch furcated legs separate the fiber strands, preventing tight bundles that could cause micro-bending losses. The included mesh pull sock facilitates safe cable installation by distributing tension evenly across the cable length, protecting the delicate fiber from installation-induced damage. **Compliance & Quality:** Manufactured in the USA and TAA compliant, this cable meets rigorous industry standards including ANSI/TIA/EIA-455-171-A-2001 attenuation testing specifications. The product carries RoHS and EU directive 2002/95/EC compliance certifications, ensuring environmental responsibility. A 90-day limited warranty provides additional peace of mind. **Ideal Applications:** Perfect for high-speed LAN interconnects, data center backbone connectivity, campus network installations, and applications requiring enhanced physical protection without sacrificing performance or installation flexibility.
