The JBX85198 20-meter SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for demanding fiber optic networks. Manufactured with precision-engineered components, this cable delivers reliable performance in telecommunications, data centers, and high-speed networking environments. Key Technical Features: This singlemode fiber patch cable utilizes a 9/125 micron core with G.657.A1 glass fiber construction, specifically designed for long-distance, high-bandwidth signal transmission. The duplex configuration enables simultaneous bidirectional communication, while the Type A to B crossover polarity ensures proper signal routing in standard network configurations. Attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm demonstrates excellent signal preservation across the fiber optic spectrum. Perfect for: - Data center interconnections - Telecommunications infrastructure - Enterprise network upgrades - Campus backbone installations - High-speed signal transmission - Mission-critical applications requiring low latency Compliance and Safety: The cable meets multiple industry standards and certifications. TAA (Trade Agreements Act) compliance ensures eligibility for government and federal procurement. RoHS/ELV directive compliance guarantees environmental responsibility. The riser-rated (OFNR) jacket provides fire-safety certification for in-building installations, meeting building codes and safety regulations. Installation Advantages: The 1.8mm outer diameter with bright yellow jacket enables easy identification and routing through cable trays and conduit systems. The 20-meter length accommodates mid-range distance requirements while remaining manageable for installation. Low insertion loss (≤0.35dB) minimizes signal degradation, reducing the need for expensive amplification equipment. Customization and Flexibility: Custom lengths are available for specialized installations requiring non-standard cable runs. This flexibility allows for precise network design without excess cable waste or additional splicing requirements. Quality Assurance: Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent performance. The 90-day limited warranty provides peace of mind for critical installations. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery, with free standard shipping on orders exceeding $99. Whether upgrading legacy systems or building new fiber optic infrastructure, the JBX85198 delivers the performance, reliability, and compliance standards required by modern networking professionals.
