The JBX43398 6-meter SC/APC to ST/APC simplex singlemode fiber patch cable represents a professional-grade solution for high-performance fiber optic networking applications. Designed to meet stringent telecommunications standards, this cable delivers exceptional optical performance and reliability. **Key Technical Specifications:** Features a 9/125 micrometer singlemode fiber core utilizing G.657.A1 glass fiber technology, ensuring low attenuation and superior signal integrity. The cable achieves insertion loss of ≤0.35dB at 1310nm and 1550nm wavelengths, with typical performance at 0.15dB. Return loss exceeds 20dB, providing excellent signal reflection control. Attenuation is rated at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), conforming to ANSI/TIA/EIA-455-171-A-2001 standards. **Construction & Compliance:** The cable features a protective 1.8mm outside diameter jacket rated OFNR (Optical Fiber Non-conductive Riser), suitable for in-building vertical applications. TAA-compliant design ensures eligibility for government and enterprise procurement. RoHS/ELV directive compliance (EU 2002/95/EC) meets environmental and safety requirements. Straight-through polarity configuration ensures reliable signal transmission without polarization concerns. **Applications & Benefits:** Ideal for telecommunications facilities, data centers, server room interconnects, and enterprise network infrastructure. The simplex configuration accommodates unidirectional signal transmission. Custom lengths available for specialized installation requirements. Backed by a 90-day limited warranty, this professional-grade patch cable ships from multiple US locations with free standard shipping on orders exceeding $99. **Installation Notes:** Ensure proper connector alignment and avoid excessive bending to maintain optimal performance. SC/APC and ST/APC connectors feature angled polished surfaces for enhanced return loss characteristics.
