The JBX43456 represents a professional-grade solution for single-strand fiber optic signal transmission in enterprise networks, telecommunications infrastructure, and data center environments. This 4-meter FC/APC to FC/APC simplex patch cable combines superior optical performance with robust construction and regulatory compliance. Optical Performance: Engineered to ANSI/TIA/EIA-455-171-A-2001 standards, this singlemode cable achieves exceptional attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The low insertion loss (≤0.35dB typical) and high return loss (≥20dB) minimize signal degradation, ensuring reliable data transmission across extended distances. The 9/125 fiber core and G.657.A1 glass fiber provide optimal performance for long-wavelength applications. Construction & Safety: The 1.8mm outside diameter cable features OFNR (riser-rated) jacketing, enabling installation in vertical building spaces and plenum areas without additional conduit. The yellow jacket facilitates rapid cable identification and organization in complex network environments. Compliance & Certification: TAA compliant and certified to RoHS/ELV (EU Directive 2002/95/EC), this cable meets government procurement requirements and environmental standards. All materials are manufactured to the highest quality standards across multiple production facilities in Taiwan, the United States, and China. Flexibility & Support: Available in custom lengths beyond the standard 4-meter configuration to match your specific installation requirements. The cable includes a comprehensive 90-day limited warranty and benefits from rapid shipping from multiple U.S. distribution centers (California, Texas, and South Carolina). Applications: Ideal for connecting network equipment, optical instruments, and telecommunications systems where single-strand transmission is required. Perfect for upgrade projects, system expansions, and new installations demanding premium optical performance.
