The JBX43028 LC/APC to LC/UPC Simplex Singlemode Fiber Patch Cable represents a professional solution for high-performance fiber optic network installations. This 85-meter cable features a 9/125 micrometer core construction with G.657.A1 grade glass fiber, optimized for single-mode signal transmission across telecommunications and data center environments. Key Technical Specifications: This cable demonstrates exceptional performance metrics, including insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB. The attenuation specifications meet ANSI/TIA/EIA-455-171-A-2001 standards, performing at 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The 1.8mm outside diameter provides optimal flexibility without compromising durability. Connector Configuration: The LC/APC (angled physical contact) to LC/UPC (ultra physical contact) configuration enables seamless integration between different connector types while maintaining signal integrity. The straight-through polarity design simplifies installation and reduces connection errors. Construction and Compliance: The yellow OFNR (optical fiber non-conductive riser-rated) jacket provides both visibility and fire safety compliance for building installations. This cable is fully RoHS and ELV compliant, meeting EU Directive 2002/95/EC requirements. TAA compliance ensures eligibility for government procurement programs. Applications and Use Cases: Ideal for telecommunications networks, data centers, campus area networks (CANs), and enterprise installations requiring long-distance fiber runs. The simplex design accommodates unidirectional signal transmission, making it suitable for applications requiring separate transmit and receive paths. Customization and Support: Custom lengths are available for specialized requirements beyond the standard 85m specification. The cable ships from strategically located US warehouses (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty, ensuring customer satisfaction and product reliability. Maintenance Considerations: Keep connector ends protected when not in use to prevent dust contamination. Store cables in cool, dry conditions away from direct sunlight. Test connections periodically to ensure optimal performance.
