The JBX83619 is a premium 40-meter LC/LC OM2 50/125 multimode fiber patch cable engineered for high-performance network environments. This duplex fiber optic cable features Type A to B crossover polarity configuration, the most common standard for duplex patch cord applications, ensuring seamless compatibility with existing network infrastructure. **Key Technical Features:** This cable utilizes bend insensitive OM2 50/125 multimode fiber with exceptional optical performance. The 1.8mm outside diameter jacketing is OFNP-rated for fire safety, while the bend insensitive design allows for tighter cable routing without compromising performance. Attenuation specifications of 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm ensure optimal signal transmission across various wavelengths. **Performance & Compliance:** Each cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, with typical insertion loss of just 0.15dB and maximum loss of 0.35dB. Return loss exceeds 60dB, guaranteeing signal integrity. Full TAA compliance and RoHS/ELV certification make this cable suitable for government and enterprise procurement requirements. **Installation & Support:** The bend insensitive fiber technology accommodates modern data center layouts with tight cable management requirements. White color coding aids in network organization and documentation. Available with custom lengths for specialized installations. Backed by a 90-day limited warranty and supported by multiple U.S. distribution centers for rapid deployment. Free standard shipping on orders exceeding $99 makes this an economical choice for network upgrades and expansions.
