The JBX43137 SC/APC to SC/UPC 30-meter simplex singlemode fiber patch cable represents a professional-grade solution for critical network infrastructure. Engineered with meticulous attention to performance specifications, this cable delivers the reliability telecommunications and data center professionals demand. Key Technical Specifications: The cable features a 9/125 singlemode core with G.657.A1 fiber specification, supporting both 1310nm and 1550nm wavelengths commonly used in modern fiber networks. Attenuation performance meets ANSI/TIA/EIA-455-171-A-2001 standards at 0.25 dB/km (1310nm) and 0.35 dB/km (1550nm). Tested insertion loss remains at or below 0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB, ensuring signal integrity. Connector Configuration: The SC/APC (angled physical contact) to SC/UPC (ultra physical contact) configuration accommodates mixed connector environments common in upgrading legacy systems or hybrid network architectures. The simplex design (single fiber strand) makes this ideal for unidirectional signal transmission applications. Construction & Safety: The 1.8mm outside diameter cable features OFNR (Optical Fiber, Non-conductive, Riser) rated yellow jacket, meeting safety requirements for in-building vertical runs and general installation environments. RoHS/ELV compliance ensures environmental responsibility and regulatory adherence. The durable plastic construction protects the core while the bright yellow color facilitates easy identification during installation and maintenance. Applications: Ideal for telecommunications closets, data center interconnects, premises distribution systems, and network backbone applications. The 30-meter length accommodates moderate-distance runs while custom lengths are available for specialized requirements. Value & Support: Included 90-day limited warranty provides peace of mind. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring quick delivery. Free standard shipping on orders exceeding $99. TAA compliance qualifies for government and institutional purchasing requirements. Maintenance: Store in cool, dry conditions. Avoid sharp bends exceeding the cable's bend radius specifications. Inspect connectors for dust or contamination before use. Compatible with standard SC/APC and SC/UPC termination practices.
