The JBX43515 ST/APC to ST/APC Simplex 9/125 Singlemode Fiber Patch Cable is a professional telecommunications component designed for high-performance network installations. This 3-meter cable combines precision engineering with practical durability for mission-critical applications. **Key Performance Features:** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable achieves exceptional low-loss characteristics with typical insertion loss of 0.15dB and guaranteed insertion loss of ≤0.35dB. Return loss exceeds 20dB, ensuring signal integrity across 1310nm and 1550nm wavelengths. The cable maintains attenuation ratings of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. **Technical Excellence:** The ST/APC (Angled Physical Contact) connectors provide superior return loss performance compared to standard PC connectors, making this cable ideal for applications requiring maximum signal fidelity. The simplex configuration delivers single-strand transmission for point-to-point connections. All measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance & Safety:** TAA (Trade Agreements Act) compliant for government and institutional procurement. RoHS/ELV directive compliance ensures environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser) rated jacket meets fire safety codes while the 1.8mm outside diameter fits standard cable management systems. **Practical Advantages:** The distinctive yellow jacket enables quick visual identification in crowded cable trays or server racks. Available in custom lengths for specific deployment requirements. Standard 3-meter length accommodates most rack-to-rack connections. Includes 90-day limited warranty. Ships from multiple US locations (California, Texas, and South Carolina) with free standard shipping on orders exceeding $99. **Ideal Applications:** Data center interconnections, telecommunications networks, FTTH (Fiber-to-the-Home) installations, laboratory testing environments, and any application requiring low-loss, high-reliability singlemode connectivity. Perfect for upgrades from multimode systems or initial deployments where performance cannot be compromised.
