The JBX88115 70-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for organizations requiring dependable fiber optic connectivity. This professional-grade cable is meticulously engineered to deliver reliable signal transmission across extended network distances while maintaining superior optical performance. Key Technical Specifications: The cable utilizes 9/125 micron singlemode fiber with G.657.A1 glass composition, specifically designed for single-wavelength transmission. Attenuation specifications meet demanding standards: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, ensuring minimal signal degradation over the full 70-meter length. Insertion loss testing confirms performance of ≤0.35dB (typical 0.15dB), while return loss exceeds ≥20dB for optimal signal integrity. Connector Configuration: The SC/UPC to ST/UPC connector arrangement follows Type A to B crossover polarity, the industry standard for duplex patch cords. Both connectors feature UPC (Ultra Physical Contact) polish for superior performance and minimal reflectance. The duplex design enables simultaneous bidirectional communication. Construction and Compliance: The cable features an OFNR (Optical Fiber Non-Conductive Riser) rated red jacket, meeting building fire codes for plenum and riser spaces. RoHS/ELV compliance ensures environmental responsibility, while TAA certification qualifies this product for government and federal procurement programs. The compact 1.8mm outer diameter facilitates installation in congested cable trays and through tight pathways. Applications and Use Cases: Ideally suited for data centers, telecommunications facilities, university campuses, and enterprise network environments. The 70-meter length accommodates longer backbone runs between equipment racks, buildings, or network nodes. Perfect for upgrading legacy systems or deploying new fiber infrastructure. Convenience Features: Qualifying orders receive free standard shipping from our Danville CA, Fort Worth TX, or Beaufort SC distribution centers. Custom length availability ensures solutions tailored to specific requirements. The 90-day limited warranty provides peace of mind on your investment.
