The JBX43389 SC/APC to ST/UPC simplex singlemode fiber patch cable represents an essential component for professionals requiring reliable optical signal transmission in telecommunications, data center, and enterprise network environments. Key Technical Specifications: This 90-meter patch cable features a 9/125 singlemode core, specifically engineered for long-distance signal transmission with minimal signal degradation. The SC/APC (angled physical contact) male connector on one end ensures optimal signal reflection management, while the ST/UPC (ultra-physical contact) connector provides secure, quick-disconnect capability on the other. With insertion loss of just 0.15dB typical and maximum 0.35dB, this cable maintains signal strength across extended distances. The return loss specification of ≥20dB ensures superior signal quality and reduced interference. Construction and Durability: Manufactured with G.657.A1 glass fiber and a 1.8mm outside diameter, the cable balances flexibility with durability. The riser-rated (OFNR) yellow jacket provides fire protection suitable for vertical runs in building plenums while offering easy visual identification. The lightweight plastic accessories and compact 5.0" packaging dimensions make installation straightforward in tight environments. Compliance and Standards: Fully TAA compliant for government procurement requirements, this cable meets EU RoHS and ELV directives, ensuring environmental responsibility. Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance and reliability. Applications and Benefits: Ideal for telecommunications infrastructure, data center connectivity, fiber-to-the-premise (FTTP) installations, and backup network systems. The simplex design suits unidirectional applications or pairs well with complementary cables for bidirectional communication. Custom lengths are available upon request, providing flexibility for unique installation requirements. Value and Support: Free standard shipping on orders exceeding $99, rapid fulfillment from multiple U.S. locations, and a comprehensive 90-day limited warranty ensure customer satisfaction. Whether upgrading existing infrastructure or establishing new optical networks, this professional-grade cable delivers the performance and reliability demanded by industry standards.
