The JBX43654 ST/APC to LC/UPC simplex fiber patch cable represents professional-grade connectivity for mission-critical fiber optic networks. This 65-meter cable combines precision engineering with reliable performance, making it an excellent choice for telecommunications providers, data centers, and enterprise IT departments. **Technical Specifications:** Features a 9/125 micrometers singlemode fiber core with G.657.A1 glass specification, providing exceptional performance in long-distance transmission scenarios. The cable achieves insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, meeting rigorous industry testing standards per ANSI/TIA/EIA-455-171-A-2001. Attenuation measurements of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal degradation over the 65-meter span. **Design & Durability:** The simplex configuration transmits signals through a single fiber strand, ideal for point-to-point applications. The 1.8mm outside diameter jacket is OFNR (Optical Fiber Nonconductive Riser) rated, meeting fire code requirements for installation in building risers and plenum spaces. The yellow jacket provides excellent visual identification in cable management systems. **Compliance & Standards:** Fully TAA compliant and manufactured to RoHS/ELV directives (EU 2002/95/EC), ensuring environmental responsibility. Available in custom lengths beyond the standard 65-meter specification for unique project requirements. **Shipping & Support:** Qualifies for free standard shipping on orders exceeding $99, with fulfillment from Danville CA, Fort Worth TX, or Beaufort SC locations. Backed by a comprehensive 90-day limited warranty. Packaged in professional 10x10x10 cases for secure delivery. This cable is essential for fiber optic network expansions, legacy system replacements, and integration projects requiring ST/APC to LC/UPC connectivity.
