The JBX42434 15-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents the gold standard for high-performance fiber optic connectivity. Engineered with precision 9/125 singlemode fiber and featuring advanced G.657.A1 glass fiber technology, this cable delivers superior optical performance in mission-critical telecommunications, data center, and network applications. Key Performance Specifications: This cable boasts exceptional low insertion loss of ≤0.35dB (typical 0.15dB), ensuring minimal signal degradation over its 15-meter length. Operating at both 1310nm and 1550nm wavelengths, it maintains consistent attenuation rates of 0.25 dB/km and 0.35 dB/km respectively. With return loss exceeding 20dB, the cable provides excellent signal reflection protection, critical for maintaining signal quality in sensitive optical systems. Design & Durability: The 1.8mm outside diameter duplex cable features a protective yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket for easy identification and superior fire safety compliance. The FC/APC to FC/UPC Type A to B crossover configuration represents the industry standard for duplex patch cord applications, ensuring seamless integration with existing infrastructure. Compliance & Certification: Fully TAA compliant and manufactured to meet RoHS/ELV directives (EU 2002/95/EC), this cable adheres to strict environmental and procurement standards. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent quality and reliability. Ideal Applications: Perfect for telecommunications facilities, data centers, fiber-to-the-premises (FTTP) installations, and any environment requiring reliable single-mode fiber connectivity. The duplex configuration supports bidirectional communication with minimal crosstalk interference. Customization & Support: Available in custom lengths to suit specific deployment requirements. Backed by a comprehensive 90-day limited warranty and supported by multiple U.S. fulfillment centers (Danville CA, Fort Worth TX, and Beaufort SC) for rapid delivery.
