The JBX43105 represents a premium solution for demanding fiber optic connectivity requirements. This 20-meter LC/APC to SC/APC simplex singlemode patch cable combines precision engineering with industry-standard compliance to deliver exceptional performance in critical network applications. **Technical Specifications:** The cable features a 9/125 micrometer singlemode fiber core utilizing G.657.A1 bend-insensitive glass fiber technology, enabling reliable performance even with tighter bend radii than conventional singlemode fiber. With an outside diameter of just 1.8mm, the cable maintains excellent flexibility while protecting the delicate glass fiber interior. The yellow OFNR (Optical Fiber Non-Conductive Riser Rated) jacket provides both visible identification and fire-safety compliance for in-building installations. **Performance Characteristics:** APC connectors on both ends minimize back-reflection, with return loss ratings of ≥20dB ensuring signal integrity. Insertion loss measures ≤0.35dB typical (maximum 0.35dB), meeting stringent ANSI/TIA/EIA-455-171-A testing standards. Attenuation specifications are optimized for both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, supporting various optical transmission protocols. **Compliance & Reliability:** Full TAA (Trade Agreements Act) compliance makes this cable suitable for government and defense sector projects. RoHS/ELV directive compliance ensures environmental responsibility. The straight-through polarity configuration simplifies installation without requiring special adapters. **Practical Applications:** Ideal for data center interconnections, telecommunications infrastructure, FTTH deployments, and equipment upgrades requiring single-strand fiber transmission. The 20-meter length covers substantial distances while maintaining signal quality. Custom lengths are available for specialized installations. **Support & Warranty:** Backed by a 90-day limited warranty and shipped with free standard shipping on orders exceeding $99 from multiple US fulfillment centers (California, Texas, and South Carolina), ensuring rapid delivery and excellent customer service.
