The JBX67638 represents a comprehensive solution for professional fiber optic network infrastructure requiring high performance and regulatory compliance. This 300-meter OM4 multimode cable incorporates 24 individual fiber strands, each precisely engineered to ISO/IEC standards for consistent signal transmission. **Key Technical Features:** The LC/UPC to LC/UPC connector configuration ensures minimal signal loss with measured insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB. Operating at both 850nm (3.5 dB/km) and 1300nm (1.5 dB/km) wavelengths, this cable supports modern multi-wavelength transmission systems. The 50/125 core-to-cladding ratio optimizes bandwidth for OM4-specific applications while maintaining backward compatibility with OM3 systems. **Construction & Durability:** Featuring bend-insensitive fiber technology, the cable withstands repeated flexing without signal degradation—essential for active network environments. The plenum-rated (OFNP) plastic jacketing complies with NFPA 262 standards, making it suitable for use in building plenums, air return spaces, and other fire-sensitive environments. At 8.0mm outside diameter, it fits standard conduit and cable trays efficiently. **Compliance & Quality Assurance:** Manufactured in the USA and TAA compliant, this cable meets rigorous regulatory standards including RoHS/ELV and EU Directive 2002/95/EC. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across the entire 300m length. The 18" furcated legs provide convenient pre-configured termination points. **Ideal Applications:** Perfect for data centers, enterprise networks, telecommunications installations, and any environment requiring reliable, long-distance multimode connectivity with enhanced fire safety requirements. Available in custom lengths and backed by a 90-day limited warranty.
