The JBX42028 85-meter LC/APC to LC/UPC duplex single mode fiber patch cable represents a premium solution for modern telecommunications infrastructure, data centers, and enterprise networking environments. This professionally engineered cable combines precision manufacturing with rigorous quality testing to deliver consistent, reliable performance in mission-critical applications. **Superior Specifications:** Built on 9/125 single mode fiber core technology (G.657.A1), this cable is specifically engineered to minimize signal degradation across standard telecom wavelengths. With typical insertion loss of just 0.15dB and maximum return loss of ≥20dB, it exceeds industry performance benchmarks. The 85-meter length provides substantial reach for backbone applications, campus networks, and distributed facility connections. **Connector Configuration:** The LC/APC-to-LC/UPC Type A to B crossover configuration enables seamless integration in mixed optical environments. LC connectors are industry-standard for high-density applications, offering superior repeatability and minimal back-reflection. The APC (angled physical contact) termination on one end paired with UPC (ultra-physical contact) on the other creates an optimal mismatch scenario that reduces back-reflection while maintaining signal integrity. **Professional Construction:** The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame-resistant properties meeting building code requirements while offering high visibility in cable management environments. The 1.8mm compact diameter facilitates easy routing through tight conduits and cable trays without compromising durability or longevity. **Compliance & Certification:** Full TAA compliance ensures government procurement eligibility, while RoHS/ELV certification guarantees environmental safety. Manufacturing across Taiwan, U.S., and China facilities ensures supply chain reliability. Every cable undergoes rigorous attenuation testing per ANSI standards. **Custom Solutions Available:** Beyond the standard 85-meter configuration, custom lengths are available to match specific installation requirements, reducing waste and optimizing performance for unique network topologies. **Shipping & Support:** With distribution centers in Danville, CA; Fort Worth, TX; and Beaufort, SC, this cable ships quickly nationwide. Orders exceeding $99 qualify for free standard shipping. The 90-day limited warranty provides peace of mind on your fiber infrastructure investment.
