The JBX42378 fiber patch cable represents enterprise-grade connectivity for modern network infrastructure. Spanning 35 meters, this duplex singlemode cable provides the extended reach necessary for campus network backbones, data center interconnects, and carrier-grade telecommunications installations. Key Technical Specifications: This cable features dual 9/125 singlemode fiber cores operating at optimal performance across standard telecommunications windows. At 1310nm, attenuation measures 0.25 dB/km, while 1550nm operation yields 0.35 dB/km—both well below industry standards. The typical insertion loss of 0.15dB ensures minimal signal degradation over the full 35-meter length, while return loss specifications of ≥20dB prevent signal reflection issues critical for video and analog services. Connector Configuration: The SC/APC to ST/UPC connector pairing (Type A to B crossover) is the industry standard for duplex patch applications, enabling straightforward integration with existing infrastructure. SC/APC connectors on one end provide angled-physical-contact superior performance, while ST/UPC connectors offer legacy compatibility with established network installations. Compliance and Quality Assurance: TAA compliance ensures procurement eligibility for government and regulated sector projects. RoHS/ELV certification confirms environmental responsibility. All cables undergo ANSI/TIA/EIA-455-171-A attenuation testing to guarantee performance consistency batch to batch. The 90-day limited warranty provides purchaser protection. Physical Characteristics: The yellow OFNR-rated jacket provides flame-resistant riser-rated protection suitable for vertical installations in building pathways. At 1.8mm outer diameter, the cable accommodates tight bend radius requirements while maintaining G.657.A1 compatibility for modern bend-insensitive applications. Custom Length Options: While this listing features 35 meters, custom lengths are available to match your specific deployment requirements. Multiple U.S. distribution centers ensure rapid fulfillment and free standard shipping on orders exceeding $99. Ideal Applications: Data center rack-to-rack connectivity, campus network backbone extensions, telecommunications carrier networks, fiber-to-the-premise installations, and any enterprise environment requiring reliable, TAA-compliant singlemode fiber connectivity.
