The JBX93036 LC/SC singlemode fiber patch cable is a professional networking solution designed for mission-critical applications requiring exceptional signal fidelity and reliability. This 4-meter duplex configuration delivers seamless connectivity between LC and SC fiber connectors, making it ideal for telecommunications infrastructure, data center interconnects, and enterprise network deployments. **Technical Excellence:** Constructed with a 9/125 singlemode core and G.657.A1 high-performance glass fiber, this cable achieves industry-leading performance metrics. The insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB ensure minimal signal degradation over longer distances. Attenuation performance is verified at both 1310nm and 1550nm wavelengths (0.25dB/km and 0.35dB/km respectively), supporting dual-window applications. **Durability and Compliance:** The orange OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides superior fire resistance and is suitable for vertical cable runs in commercial buildings. With an outer diameter of just 1.8mm, the cable maintains flexibility for tight installations. Full RoHS/ELV and TAA compliance certification ensures government procurement eligibility and environmental responsibility. **Versatility and Convenience:** While optimized for 4-meter runs, custom lengths are available to suit specific deployment requirements. The Type A to B crossover polarity configuration is standard for duplex patch cords, ensuring compatibility with most enterprise equipment. Domestic and international manufacturing (Taiwan, US, China) ensures reliable supply chains. **Support and Warranty:** Every cable undergoes rigorous ANSI/TIA/EIA standards testing before shipment. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 reduces procurement costs. Ships from strategically located fulfillment centers in California, Texas, and South Carolina for rapid delivery. Ideal for network administrators, telecommunications professionals, and data center operators seeking premium fiber connectivity with verified performance and compliance assurance.
