The JBX90050 LC/SC duplex singlemode fiber patch cable represents the gold standard in optical connectivity solutions for professional networking environments. This 45-meter cable is specifically engineered to meet the rigorous demands of telecommunications companies, internet service providers, data centers, and enterprise network installations. **Superior Optical Performance:** Built with 9/125 singlemode fiber and G.657.A1 glass technology, the JBX90050 delivers exceptional optical characteristics. With insertion loss rated at ≤0.35dB (typically just 0.15dB) at both 1310nm and 1550nm wavelengths, and return loss exceeding 20dB, this cable minimizes signal degradation over extended distances. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent, predictable performance. **Compliance and Regulatory Features:** This cable is fully TAA (Trade Agreements Act) compliant, making it ideal for government and federally-funded projects. RoHS/ELV compliance demonstrates environmental responsibility, while OFNR riser-rating allows safe installation in vertical cable runs within building walls. The cable meets EU directive 2002/95/EC requirements. **Practical Design Elements:** The distinctive pink color jacket facilitates rapid identification during dense installations, reducing installation errors and simplifying network documentation. The Type A to B crossover polarity configuration represents industry-standard duplex patch cord design. At just 1.8mm outer diameter, the cable offers flexibility for routing through tight spaces and conduit systems. **Flexibility and Customization:** While the JBX90050 is specifically configured at 45 meters, custom lengths are available to match your exact installation requirements, eliminating unnecessary cable slack and improving network aesthetics. **Warranty and Support:** Every cable includes a 90-day limited warranty, backed by rapid shipping from multiple U.S. locations (Danville CA, Fort Worth TX, and Beaufort SC). Orders over $99 qualify for free standard shipping. **Applications:** Ideal for singlemode fiber backbone runs, telecommunications infrastructure, metro-area networks (MANs), wide-area network (WAN) connections, and carrier-class network deployments where optical performance and regulatory compliance are non-negotiable.
