The 90m FC/APC to ST/UPC Simplex 9/125 Singlemode Fiber Patch Cable (Model JBX43629) represents a premium solution for fiber optic network installations demanding precision and reliability. Engineered to meet international telecommunications standards, this cable bridges the gap between two of the most prevalent connector types in professional networking environments. **Technical Excellence** Built on a 9/125 singlemode core with G.657.A1 specification, this cable ensures minimal signal loss over extended distances. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB provide exceptional optical performance. Attenuation testing confirms specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, meeting ANSI/TIA/EIA-455-171-A-2001 standards. **Superior Construction** The 1.8mm outside diameter jacketing with OFNR (Optical Fiber Non-conductive Riser) rating ensures compliance with building fire codes while providing excellent protection against environmental stressors. The plastic accessory materials and RoHS/ELV compliance demonstrate our commitment to safety and environmental responsibility. **Professional Connectivity** The FC/APC to ST/UPC configuration addresses interoperability needs in heterogeneous network environments where equipment from different manufacturers must communicate seamlessly. This simplex design (one fiber strand) provides dedicated directional transmission ideal for point-to-point connections. **Value and Compliance** TAA compliant for government procurement requirements, this cable includes a 90-day limited warranty and qualifies for free standard shipping on orders exceeding $99. Custom lengths are available for specialized installations. Manufactured in Taiwan, the USA, or China, this cable is stocked at multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. **Ideal Applications** Perfect for telecommunications closets, data centers, campus networks, fiber-to-the-premise installations, and laboratory testing environments where singlemode fiber transmission is required.
