The JBX42104 LC/APC to SC/APC duplex single mode fiber patch cable represents a premium solution for demanding network environments requiring precise signal transmission and long-distance connectivity. This 25-meter cable is engineered with industry-leading specifications to ensure maximum performance and reliability. Key Technical Features: This duplex cable features a 9/125 micron single mode core, the industry standard for long-distance telecommunications. The G.657.A1 glass fiber specification provides enhanced bend insensitivity, making it suitable for installations where routing flexibility is essential. With measured insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB, signal integrity is maintained across both 1310nm and 1550nm wavelengths. Connector Configuration: The LC/APC to SC/APC Type A to B crossover configuration is the most common duplex arrangement for network patch applications. APC (Angled Physical Contact) connectors feature a superior 8-degree angle cut, reducing back-reflection and optimizing performance in sensitive environments like DWDM systems, fiber-to-home installations, and high-speed data centers. Applications & Use Cases: Ideal for ISP backbone connections, telecommunications networks, data center interconnects, and enterprise-grade fiber optic installations. The yellow jacket provides excellent visibility in color-coded network systems, reducing installation errors and simplifying maintenance procedures. Compliance & Standards: Fully TAA compliant for government and institutional procurement. Manufactured to ANSI/TIA/EIA-455-171-A-2001 standards with RoHS/ELV compliance. OFNR (Optical Fiber Non-Conductive Riser) rating ensures safe use in vertical runs between building floors without requiring conduit in many jurisdictions. Durability & Warranty: The 1.8mm compact outside diameter combines durability with installation flexibility. Backed by a 90-day limited warranty. Custom lengths available to meet specific project requirements. Ships from multiple U.S. locations ensuring rapid delivery with free standard shipping on orders exceeding $99.
