The JBX43811 50m SC/APC to E2000/APC simplex singlemode fiber patch cable represents professional-grade fiber optic connectivity engineered for mission-critical telecommunications and data center environments. This cable bridges two industry-standard connector types, providing flexibility in network configurations while maintaining superior optical performance. Key Technical Specifications: This singlemode fiber patch cable features a 9/125 micron core with G.657.A1 glass fiber specifications, delivering exceptional signal quality for long-distance transmission. The measured insertion loss of ≤0.35dB (typically 0.15dB) and return loss of ≥20dB exceed industry standards established by ANSI/TIA/EIA-455-171-A-2001. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure reliable performance across dual-wavelength systems. Construction & Durability: The cable features a robust 1.8mm outer diameter with OFNR (Optical Fiber Nonconductive Riser) rated yellow jacket, meeting fire-safety requirements for in-building installations. The straightthrough polarity configuration ensures predictable signal path without confusion during deployment. RoHS/ELV compliance and TAA certification make this cable suitable for government and regulated procurement environments. Applications & Use Cases: Ideal for telecommunications infrastructure, data center patch panels, FTTH (Fiber-to-the-Home) installations, and high-speed network deployments. The SC/APC to E2000/APC configuration serves facilities requiring connector interoperability, particularly in European and international installations where E2000 connectors are prevalent. Customization & Support: Available in custom lengths beyond the standard 50m offering, allowing tailored solutions for specific installation requirements. The 90-day limited warranty provides confidence in product reliability, while domestic warehousing in California, Texas, and South Carolina enables rapid fulfillment. Free standard shipping on qualifying orders reduces total acquisition costs. Optimal performance requires proper handling, avoiding excessive bending beyond the fiber's minimum bend radius and protecting connector ends from contamination. This investment delivers years of reliable service in demanding optical transmission environments.
