The JBX65520 represents the pinnacle of multimode fiber optic cable engineering, delivering enterprise-grade performance for mission-critical network infrastructure. This 120-meter OM4 LC/LC armored cable is purpose-built for organizations requiring reliable, high-bandwidth connectivity in challenging installation environments. **Superior Performance Specifications:** With OM4 50/125 multimode fiber core, this cable provides exceptional signal integrity across standard datacenter wavelengths. At 850nm, attenuation reaches only 3.5 dB/km, while 1300nm performance delivers an impressive 1.5 dB/km. The low insertion loss of ≤0.35dB (typical 0.15dB) and high return loss of ≥20dB ensure minimal signal degradation and optimal network reliability. These specifications comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Robust Construction & Durability:** The micro-armored jacket with 3.0mm diameter profile protects against crushing, abrasion, and environmental hazards while maintaining installation flexibility. Bend-insensitive fiber technology eliminates performance penalties when routing around obstacles, reducing installation costs and time. The plenum-rated (OFNP) plastic jacketing with fiber strands ensures compliance with stringent fire safety codes, making it ideal for in-plenum and vertical riser applications. **Installation Excellence:** The 18-inch furcated legs pre-separate the two strands, streamlining termination processes in high-density fiber distribution frames. The integrated mesh pull sock distributes tension evenly during installation, protecting fiber integrity and reducing mechanical stress. These features minimize installation time and potential damage. **Regulatory Compliance & Quality Assurance:** Manufactured in the USA, this cable is RoHS/ELV compliant and TAA certified, meeting procurement requirements for government and regulated industries. The 90-day limited warranty provides assurance of quality manufacturing standards. Free standard shipping on orders over $99 with convenient shipping from Danville, CA or Fort Worth, TX locations. **Ideal Applications:** Perfect for datacenter interconnects, campus backbone networks, high-speed LAN environments, and any application requiring reliable multimode fiber transmission over 120-meter distances. The armored construction makes it particularly suitable for outdoor and industrial installations where standard cables prove insufficient.
