The JBX42258 LC/APC to ST/UPC Duplex Singlemode Fiber Patch Cable is a professional-grade networking solution engineered for mission-critical telecommunications and data center applications. With a substantial 35-meter length, this cable enables extended connection distances while maintaining exceptional signal integrity and minimal attenuation. **Technical Specifications:** This duplex patch cable features dual 9/125 singlemode fiber strands with G.657.A1 glass fiber composition, meeting the highest industry standards for long-distance signal transmission. The cable delivers outstanding performance metrics: insertion loss of ≤0.35dB at 1310nm and ≤0.35dB at 1550nm, with typical performance at 0.15dB and return loss exceeding 20dB. The 1.8mm outside diameter allows for flexible routing through cable trays and conduit systems. **Standards Compliance:** TAA (Trade Agreements Act) certified for federal government procurement, this cable also meets RoHS/ELV directives and EU 2002/95/EC compliance requirements. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reliable third-party validation of performance specifications. **Connector Configuration:** The LC/APC to ST/UPC connector pairing accommodates Type A to B crossover polarity, the industry standard for duplex patch applications. This configuration enables seamless integration with existing network infrastructure while supporting full-duplex communication across a single cable assembly. **Installation Features:** The yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides flame resistance and smoke control for building-code compliance in non-plenum environments. This durable construction withstands typical installation stresses while maintaining optical performance throughout the cable's operational lifespan. **Applications:** Perfect for telecommunications closet interconnects, data center rack-to-switch connections, and campus network backbone installations. The 35-meter length eliminates the need for multiple shorter cables, reducing connection points and improving system reliability. **Value Proposition:** Available with custom length options for specific deployment requirements, shipped from multiple US locations ensuring rapid delivery. Qualified orders receive free standard shipping, and all units include a 90-day limited warranty providing peace-of-mind protection. This TAA-compliant solution represents an excellent choice for organizations requiring certified networking components with proven performance and compliance credentials.
