The JBX43723 SC/APC to LC/UPC singlemode fiber patch cable represents a critical component in modern optical networking infrastructure. Engineered for precision and reliability, this 12-meter cable bridges the gap between SC/APC and LC/UPC connectors, accommodating legacy systems and modern equipment in unified networks. **Technical Excellence** Constructed with 9/125 singlemode fiber and G.657.A1 glass specification, this cable provides exceptional performance characteristics. The insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards, ensuring minimal signal degradation across transmission wavelengths (1310nm and 1550nm). Attenuation specs of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm demonstrate performance consistency for long-distance applications. **Compliance and Safety** TAA compliance satisfies federal procurement requirements, making this cable suitable for government contractors and regulated industries. RoHS/ELV directive compliance ensures environmental responsibility. The OFNR riser-rated jacket provides fire safety certification for deployment in building plenum and riser spaces without conduit. **Practical Applications** Ideal for datacenter interconnects, telecom backbone networks, enterprise campus fiber runs, and equipment interoperability scenarios. The simplex straight-through polarity configuration serves unidirectional transmission needs in CWDM/DWDM systems, PON networks, and redundant optical paths. **Flexibility and Support** Available in custom lengths for non-standard requirements. Multiple US fulfillment centers (California, Texas, South Carolina) ensure quick delivery. The yellow jacket provides high visibility for rapid identification in dense cable environments. Backed by 90-day limited warranty and manufactured in Taiwan, US, or China to meet capacity demands.
