The JBX43339 SC/APC to FC/APC fiber patch cable represents a critical component for modern telecommunications infrastructure. Specifically designed as a simplex cable, it transmits fiber signals unidirectionally, making it ideal for applications requiring dedicated receive or transmit pathways. Technical Excellence: This 7-meter cable features a 9/125 singlemode core constructed from G.657.A1 glass fiber, providing exceptional signal integrity over extended distances. The attenuation specifications—0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm—ensure minimal signal loss, critical for long-haul telecommunications. With measured insertion loss of ≤0.35dB and return loss exceeding 20dB, this cable consistently performs within ANSI/TIA/EIA standards. Professional Features: The bright yellow 2mm diameter jacket facilitates quick identification in complex cable management scenarios while providing OFNR (Optical Fiber, Non-conductive, Riser) rated fire protection. SC/APC and FC/APC connectors feature angled physical contacts that minimize back-reflection, essential for sensitive telecommunications equipment. Compliance and Reliability: Fully TAA compliant and RoHS/ELV certified, this cable meets government procurement requirements. Manufactured across trusted facilities in Taiwan, the US, and China, it maintains consistent quality across all production locations. Customization and Flexibility: While this listing offers a standard 7-meter length, custom lengths are available to accommodate specific installation requirements. The straight-through polarity design ensures straightforward connectivity without complex configuration. Applications: Ideal for telecommunications carriers, ISPs, data centers, and enterprise networks upgrading to singlemode infrastructure. Perfect for backbone connections, inter-building links, and equipment interconnections where reliable, high-performance signal transmission is non-negotiable. Value Proposition: With free standard shipping on orders exceeding $99 and a 90-day limited warranty, this professional-grade cable delivers enterprise-quality performance at competitive pricing.
