The JBX43066 is a professional-grade fiber optic patch cable designed for critical network infrastructure, telecommunications, and data center applications. This 4-meter simplex cable seamlessly connects LC/APC connectors to SC/UPC connectors, facilitating reliable single-direction fiber signal transmission in systems requiring unidirectional communication. Technical Excellence: Constructed with a 9/125 micron singlemode core, this cable delivers superior performance characteristics. The G.657.A1 glass fiber specification ensures compatibility with modern bend-insensitive fiber optic systems while maintaining exceptional light transmission efficiency. Insertion loss measures ≤0.35dB (0.15dB typical), and return loss exceeds 20dB, both tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm support long-distance signal integrity. Compliance and Safety: TAA compliant for GSA Schedule and government procurement programs. OFNR riser-rated jacketing provides fire safety for in-building backbone cabling. RoHS/ELV directive compliance (EU 2002/95/EC) meets environmental and regulatory standards. The 1.8mm outside diameter and plastic construction ensure durability without compromising flexibility. Practical Features: The distinctive yellow jacket simplifies cable identification and management in complex infrastructure environments. Straight-through polarity configuration accommodates standard network topologies. Available in custom lengths beyond the standard 4-meter offering, allowing deployment flexibility for various installation requirements. Reliability and Support: Backed by a comprehensive 90-day limited warranty. Manufactured in Taiwan, US, or China with consistent quality standards. Ships from three strategic US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Free standard shipping on orders exceeding $99. Ideal Applications: Data center interconnects, telecommunications networks, enterprise LAN installations, fiber-to-the-premises (FTTP) deployments, and any application requiring reliable singlemode fiber signal transmission with LC/APC to SC/UPC connectivity.
