The JBX43472 55-meter FC/APC simplex singlemode fiber patch cable represents a reliable solution for professional fiber optic network installations. Engineered with precision components and tested to rigorous industry standards, this cable delivers consistent performance in telecommunications, data centers, and enterprise network environments. **Technical Specifications:** This single-strand (simplex) cable features a robust 9/125 micron singlemode core with G.657.A1 grade glass fiber, specifically designed for long-distance signal transmission with minimal attenuation. The measured attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure optimal performance across standard telecommunications wavelengths. Insertion loss testing confirms ≤0.35dB performance (typical 0.15dB), while return loss specifications exceed 20dB, meeting or exceeding ANSI/TIA/EIA-455-171-A-2001 standards. **Construction & Safety:** The yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides fire safety certification required for building installations. The 1.8mm outside diameter balances durability with flexibility, accommodating tight installation spaces without compromising signal integrity. Straight-through polarity configuration ensures straightforward point-to-point connections without crossover confusion. **Compliance & Certifications:** TAA compliant, this cable meets government procurement requirements and adheres to RoHS/ELV directives (EU directive 2002/95/EC), making it suitable for regulated enterprise and public sector applications. **Availability & Support:** Available in custom lengths to match specific installation requirements. Ships from strategically located US facilities (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty ensuring customer confidence in your network infrastructure investment.
