The JBX42514 2.5-meter ST/APC to ST/APC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical fiber optic applications. Manufactured to exacting standards with materials sourced from Taiwan, the US, and China, this cable delivers consistent, reliable performance in demanding environments. Technical Excellence: Built around a 9/125 micron singlemode core conforming to G.657.A1 specifications, this cable achieves exceptional optical performance. The insertion loss specification of ≤0.35dB (with typical performance of 0.15dB) ensures minimal signal attenuation, while the return loss of ≥20dB maintains signal integrity. Attenuation testing confirms performance at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, supporting diverse telecommunications applications. Build Quality & Compliance: The distinctive yellow OFNR (Optical Fiber Non-conductive Riser) jacketing provides fire-rated protection suitable for vertical cable runs in building infrastructures. With a slim 1.8mm outer diameter, the cable facilitates flexible routing through cable trays and conduits. Type A to B crossover polarity configuration is optimized for standard duplex patch cord applications. TAA compliance makes this cable eligible for federal and government procurement, while RoHS/ELV directive adherence ensures environmental responsibility. The 90-day limited warranty provides peace-of-mind protection for your investment. Applications: Ideal for telecommunications networks, data center interconnections, fiber-to-the-premises (FTTP) installations, and enterprise LAN environments. The 2.5-meter length accommodates typical patch panel to equipment distances while minimizing excess coil. Customization Available: If standard lengths don't meet your requirements, custom lengths are available to specification. Free standard shipping applies to orders exceeding $99, with convenient fulfillment from multiple US distribution centers in California, Texas, and South Carolina.
