The JBX43135 20-meter SC/APC to SC/UPC simplex singlemode fiber patch cable represents a reliable solution for demanding fiber optic network installations. This cable combines precision engineering with cost-effective performance for telecommunications professionals and IT infrastructure managers. Technical Excellence: Built on G.657.A1 singlemode fiber technology with a 9/125 micron core, this cable delivers superior performance across standard C-band (1550nm) and L-band (1310nm) telecommunications wavelengths. The SC/APC termination minimizes back-reflection with return loss exceeding 20dB, while the SC/UPC connector provides wide compatibility with standard network equipment. Performance Specifications: Independent laboratory testing confirms insertion loss of ≤0.35dB (typical 0.15dB), ensuring minimal signal degradation over the 20-meter length. Attenuation characteristics of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm comply with all major telecommunications standards. Durability & Identification: The yellow 1.8mm diameter jacket features riser-rated (OFNR) jacketing for flame resistance and durability in building environments. Distinctive yellow coloring enables quick identification in cable management systems and reduces installation errors. Compliance & Support: TAA compliant for government and institutional procurement, this cable meets RoHS/ELV directives ensuring environmental responsibility. Manufacturing across Taiwan, US, and China facilities ensures supply chain reliability. Applications: Ideal for data center patch panels, DWDM systems, telecommunications network upgrades, enterprise fiber backbones, and laboratory testing environments. The simplex configuration supports unidirectional transmission where duplex communication isn't required. Customization Available: Beyond the standard 20m length, custom cable assemblies are available to meet specific deployment requirements. Convenient free standard shipping on orders exceeding $99 makes bulk procurement economical. Warranty: All products include a comprehensive 90-day limited warranty, demonstrating manufacturer confidence in quality and reliability.
