The JBX43242 LC/APC to ST/UPC simplex singlemode fiber patch cable represents professional-grade connectivity solutions for telecommunications, data centers, and enterprise networks. This 1.5-meter cable features precision-engineered connectors and superior optical performance specifications that meet or exceed industry standards. **Technical Excellence:** The cable utilizes a 9/125 singlemode core with G.657.A1 glass fiber construction, delivering insertion loss of ≤0.35dB and return loss ≥20dB. Performance is verified through rigorous attenuation testing (1310nm: 0.25dB/km; 1550nm: 0.35dB/km) in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. The straight-through polarity configuration ensures reliable signal transmission without complex configurations. **Durable Construction:** The OFNR riser-rated jacketing with 1.8mm outer diameter provides superior protection against physical damage, moisture, and environmental stress. RoHS/ELV compliant materials ensure environmental responsibility and regulatory compliance across North American and EU markets. **TAA Compliance & Government-Ready:** As a TAA-compliant product, this cable qualifies for federal purchasing requirements, making it ideal for government agencies, defense contractors, and institutional networks requiring stringent compliance standards. **Practical Benefits:** The distinctive yellow color-coding facilitates rapid identification in dense fiber installations, reducing installation time and maintenance complexity. The cable's compact 1.8mm diameter fits standard conduit systems and wall plates without modifications. **Flexibility & Availability:** Custom length options are available for specific deployment requirements. Multiple U.S. warehouse locations (Danville CA, Fort Worth TX, Beaufort SC) ensure fast order fulfillment. Free standard shipping on orders over $99 provides cost-effective connectivity solutions. **Ideal Applications:** Perfect for telecommunications infrastructure, data center migration projects, network upgrades, laboratory equipment connectivity, and any deployment requiring singlemode fiber signal transmission. The simplex configuration suits applications with unidirectional data flow requirements. Backed by a 90-day limited warranty, the JBX43242 delivers reliable, standards-compliant fiber connectivity for mission-critical network installations.
