The JBX42064 LC/APC to SC/UPC 2.5m Duplex Singlemode Fiber Patch Cable represents a premium solution for telecommunications, data center, and enterprise network environments. This carefully engineered optical accessory combines precision connector technology with high-performance single-mode fiber to deliver reliable, low-loss signal transmission across your critical infrastructure. Key Technical Specifications: This duplex patch cable features 9/125 singlemode fiber construction meeting G.657.A1 standards, ensuring compatibility with modern fiber networks while maintaining backward compatibility with existing installations. The LC/APC to SC/UPC connector configuration provides the crossover polarity (Type A to B) that's standard for most duplex applications. Attenuation performance is outstanding at 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km), with insertion loss typically measuring just 0.15dB and never exceeding 0.35dB—well below industry standards. Return loss exceeds 20dB, ensuring minimal signal reflection. Construction and Compliance: The 1.8mm jacketing utilizes OFNR (Riser Rated) construction, meeting building codes for indoor installation without conduit. The bright yellow jacket aids rapid identification during maintenance and troubleshooting. TAA compliance and RoHS/ELV certification make this cable suitable for government and regulated procurement, manufactured in Taiwan, the US, or China depending on availability. Applications and Benefits: Ideal for connecting network switches, patch panels, and optical distribution frames in data centers, carrier networks, and enterprise environments. The 2.5-meter length provides flexibility in equipment spacing, while custom length availability accommodates specialized installations. The 90-day limited warranty and bulk packaging (10x10x10) support both individual deployments and larger infrastructure projects. Value Proposition: With free standard shipping on orders exceeding $99 and warehousing at multiple US locations (Danville CA, Fort Worth TX, Beaufort SC), rapid delivery is assured. This TAA-compliant, professionally-tested optical accessory delivers enterprise-grade reliability at competitive pricing.
