The JBX42361 SC/APC to ST/UPC duplex singlemode fiber patch cable represents a critical infrastructure component for modern telecommunications networks. Designed for organizations requiring reliable fiber connectivity with government compliance certification, this 1-meter cable delivers professional-grade performance specifications. Technical Excellence: Built on 9/125 singlemode fiber architecture compliant with G.657.A1 standards, this cable minimizes attenuation at 0.25 dB/km (1310nm) and 0.35 dB/km (1550nm). The precisely engineered SC/APC and ST/UPC connectors achieve insertion loss specifications of ≤0.35dB with typical performance at 0.15dB, ensuring minimal signal degradation. Return loss exceeding 20dB prevents problematic back-reflections that could compromise network performance. Connector Configuration: The SC/APC to ST/UPC arrangement provides Type A to B crossover polarity—the most common and versatile configuration for duplex patch cord applications. This crossover design simplifies network design by enabling bidirectional communication on properly configured network segments. Construction & Durability: The 1.8mm diameter yellow outer jacket provides immediate visual identification within complex cable management systems while offering robust protection. OFNR (Optical Fiber Non-conductive Riser) rated jacketing ensures compliance with building fire codes for in-wall and plenum-adjacent installations. The duplex design enables simultaneous bidirectional transmission using two distinct fiber strands within a single protective sheath. Compliance & Sustainability: TAA (Trade Agreements Act) compliance certifies this product meets federal procurement requirements. Full RoHS/ELV directive compliance demonstrates environmental responsibility. Manufactured in Taiwan, the US, or China, this cable benefits from global supply chain redundancy. Customization & Support: While this listing features 1-meter length, custom lengths are available to precisely fit your installation requirements. Each cable includes a 90-day limited warranty covering manufacturing defects. Insertion loss testing conforms to rigorous ANSI/TIA/EIA-455-171-A-2001 standards. Ideal Applications: Perfect for enterprise data centers, telecommunications facilities, university research networks, and government installations requiring compliant, high-performance fiber interconnections. The yellow jacket simplifies identification in densely cabled environments.
