The JBX88272 is a professional 55-meter ST/ST duplex singlemode fiber patch cable engineered for high-performance network infrastructure and telecommunications applications. This TAA-compliant solution meets government procurement requirements while delivering exceptional optical performance. **Technical Specifications:** This duplex cable features dual 9/125 singlemode fiber strands with G.657.A1 glass composition, providing excellent bend performance and signal integrity. The cable maintains impressive attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm wavelengths. Typical insertion loss measures just 0.15dB with a maximum of 0.35dB, while return loss exceeds 20dB for superior signal quality. **Design & Compatibility:** Equipped with ST/UPC connectors in Type A to B crossover configuration—the industry standard for duplex patch cords—this cable ensures seamless integration with existing fiber infrastructure. The compact 1.8mm outside diameter facilitates easy routing through conduits and cable trays without excessive bulk. **Installation & Durability:** The OFNR (Optical Fiber Non-Conductive Riser) rated jacketing provides fire safety compliance for vertical runs in commercial buildings. This durable plastic construction protects the fiber strands while maintaining flexibility for installation in tight spaces. **Compliance & Standards:** Fully compliant with RoHS/ELV directives and TAA requirements, this cable meets ANSI/TIA/EIA-455-171-A standards for attenuation testing. Manufactured in Taiwan, the US, and China, it's backed by a 90-day limited warranty. **Applications:** Ideal for data centers, telecommunications closets, network equipment interconnection, and long-distance signal transmission. Available in custom lengths for specialized requirements. Free standard shipping on orders exceeding $99, with multiple fulfillment locations ensuring rapid delivery.
