The JBX43631 ST/APC to LC/UPC Simplex Fiber Patch Cable represents a critical component in modern fiber optic network infrastructure. This precision-engineered 1-meter cable connects disparate fiber network equipment with exceptional reliability and minimal signal loss, making it essential for telecommunications, data centers, medical imaging systems, and broadcast facilities. **Technical Excellence:** Constructed with 9/125 singlemode fiber, this cable supports long-distance transmissions with superior performance. The ST/APC (Straight Tip/Angled Physical Contact) connector terminates in a 2.5mm ferrule with angled polish, while the LC/UPC (Lucent Connector/Ultra Physical Contact) terminus features 1.25mm form factor with flat polish. This configuration accommodates diverse legacy and modern equipment architectures. Insertion loss measurements of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed industry expectations, ensuring signal integrity across 1310nm and 1550nm wavelengths. **Compliance & Standards:** TAA (Trade Agreements Act) compliance enables procurement for government contracts and regulated industries. RoHS/ELV directive compliance ensures environmental responsibility. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. G.657.A1 fiber classification provides bend-insensitive characteristics for installation flexibility. **Durability & Installation:** The robust 1.8mm outer diameter with OFNR riser-rated yellow jacket withstands demanding environments while remaining clearly visible for network identification. The simplex (single-strand) design suits point-to-point connections, reducing cable clutter compared to duplex alternatives. **Availability & Support:** Available in custom lengths beyond the standard 1-meter configuration, with manufacturing capabilities in Taiwan, USA, and China. Strategic warehouse locations (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid shipping. The 90-day limited warranty provides confidence in product quality and manufacturer support.
