The JBX43494 ST/APC to ST/UPC Simplex 9/125 Singlemode Fiber Patch Cable represents a premium connectivity solution for professional network infrastructure deployments. This 15-meter cable bridges ST connector types—with the angled physical contact (APC) termination on one end and ultra-physical contact (UPC) on the other—enabling flexible system integration while maintaining exceptional optical performance. Technical Excellence: Constructed with G.657.A1 singlemode glass fiber, the 9/125 core provides minimal modal dispersion and optimal signal clarity across telecommunications wavelengths. Performance specifications include insertion loss of ≤0.35dB at typical operation (0.15dB nominal), with attenuation measured at 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km) wavelengths. Return loss of ≥20dB ensures signal reflection minimization, critical for high-speed data transmission. Build Quality & Compliance: The yellow OFNR (Optical Fiber Non-conductive Riser) jacket meets building fire codes while providing visual identification in cable management systems. The 1.8mm outside diameter facilitates efficient routing through existing conduit and cable trays. TAA compliance certifies suitability for government and institutional procurement, while RoHS/ELV certification confirms environmental safety standards compliance. Testing follows ANSI/TIA/EIA-455-171-A standards. Application Versatility: Ideal for data centers, telecommunications facilities, campus networks, and enterprise installations requiring reliable single-mode fiber connections. The straight-through polarity and simplex configuration support point-to-point signal transmission. Custom lengths available for unique installation requirements. Warranty & Support: 90-day limited warranty provides peace of mind, with expedited shipping options from strategically located US distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC).
