The JBX42031 LC/APC Single Mode Fiber Patch Cable represents the gold standard in optical connectivity solutions for modern network infrastructure. This 1-meter duplex cable combines precision engineering with stringent quality control to deliver uncompromising performance in demanding environments. **Superior Optical Performance** With a 9/125 micron single mode core, this cable minimizes signal degradation and maximizes transmission distance. The APC (Angled Physical Contact) connectors provide return loss ≥20dB, significantly reducing back-reflections that can degrade system performance. Measured insertion loss of ≤0.35dB ensures minimal signal attenuation at critical 1310nm and 1550nm wavelengths, maintaining signal integrity across long distances. **Professional-Grade Construction** The G.657.A1 glass fiber specification supports bend-insensitive applications while maintaining compatibility with standard single mode systems. The OFNR-rated jacket delivers fire safety compliance essential for building installations. At 1.8mm outer diameter, the compact design facilitates routing through crowded cable trays and conduit systems without compromising durability. **Compliance and Reliability** TAA compliance ensures this cable meets government procurement standards for federal projects. RoHS/ELV certification confirms environmentally responsible manufacturing. Rigorous ANSI/TIA/EIA-455-171-A testing validates performance consistency. The distinctive yellow jacket provides visual identification, reducing installation errors and simplifying maintenance. **Ideal Applications** Perfect for data center interconnects, campus backbone networks, telecommunications infrastructure, and DWDM systems. The crossover polarity configuration works seamlessly with most duplex networking equipment. **Custom Solutions Available** While this 1-meter configuration serves standard patching needs, custom lengths accommodate unique installation requirements. Free standard shipping on orders over $99 provides exceptional value. Ships from multiple U.S. locations for rapid delivery. The 90-day limited warranty guarantees peace of mind on your network investment.
