The 45m SC/APC to FC/APC Simplex 9/125 Singlemode Fiber Patch Cable represents professional-grade optical connectivity engineered for precision telecommunications, data center, and enterprise network applications where signal fidelity and reliability are paramount. **Technical Excellence** Built with a 9/125 singlemode core using G.657.A1 specification glass fiber, this cable delivers exceptional performance across industry-standard wavelengths. The SC/APC (Subscriber Connector/Angled Physical Contact) and FC/APC (Ferrule Connector/Angled Physical Contact) connectors feature angled 8-degree polished surfaces that minimize back-reflection and optimize return loss (≥20dB). Insertion loss measures ≤0.35dB typical (0.15dB), with predictable attenuation of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. **Quality and Compliance** Manufactured to rigorous ANSI/TIA/EIA-455-171-A-2001 attenuation standards, this cable is fully tested for performance integrity. TAA compliance satisfies government procurement mandates, while RoHS/ELV certification ensures environmental safety. The OFNR (Optical Fiber Non-conductive Riser) yellow jacket provides flame resistance, meeting building code requirements for in-building installations. **Practical Design** The 1.8mm outer diameter and durable plastic construction fit standard patch panels and equipment configurations. Straight-through polarity design ensures correct signal transmission without requiring crossed connections. The 45-meter length accommodates moderate-distance interconnects within office buildings, data centers, and network facilities. **Flexibility and Support** Custom lengths available to match specific deployment requirements. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. 90-day limited warranty covers manufacturing defects. Ideal for telecommunications professionals, network technicians, and IT infrastructure specialists upgrading or expanding fiber-optic networks with consistent, high-performance connectivity.
