The JBX88112 55-meter SC/ST duplex singlemode fiber patch cable represents professional-grade connectivity designed for mission-critical network infrastructure. Built with precision engineering and quality components, this cable delivers the performance characteristics required in telecommunications, data centers, and high-speed networking environments. Technical Excellence: With a 9/125 singlemode fiber core and G.657.A1 glass fiber construction, this cable minimizes chromatic and modal dispersion, enabling reliable long-distance signal transmission. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover connectivity—the industry-standard polarity arrangement for duplex patch cords. Insertion loss specifications of ≤0.35dB (typical 0.15dB) and return loss ≥20dB ensure minimal signal loss and reflection, maintaining signal quality across extended runs. Compliance and Safety: Full TAA (Trade Agreements Act) compliance makes this cable eligible for government and institutional procurement. RoHS/ELV certification confirms environmental responsibility and hazard-free materials. The riser-rated (OFNR) outer jacket meets building code requirements for non-plenum installations, providing both safety and flexibility. Practical Advantages: • 55-meter length reduces connection point failures • Distinctive red jacket simplifies network identification and troubleshooting • 1.8mm diameter balances flexibility with durability • Suitable for telecommunications rooms, server racks, and network cabinets • Excellent for campus backbone networks and inter-building links Applications: Ideal for fiber-to-the-desktop installations, data center backbone connectivity, telecommunications infrastructure, and any application requiring singlemode fiber performance over substantial distances. The dual-fiber duplex design supports simultaneous bidirectional transmission. Quality Assurance: Attenuation testing conducted per ANSI/TIA/EIA-455-171-A standards guarantees performance specifications. 90-day limited warranty provides peace of mind. Ships from multiple U.S. locations with free standard shipping on orders over $99. Custom length options available for specialized installations.
