The JBX89202 55-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for enterprise-grade fiber optic networking. Specifically designed for single-mode transmission, this cable utilizes a 9/125 micron core with G.657.A1 glass fiber technology, enabling superior signal fidelity over extended distances. The duplex configuration provides two independent fiber strands, allowing simultaneous bidirectional communication for full-duplex operations. Key Technical Specifications: This cable has been rigorously tested to meet ANSI/TIA/EIA-455-171-A-2001 standards with exceptional performance metrics. Insertion loss measures ≤0.35dB at 0.15dB typical, while return loss exceeds 20dB, ensuring minimal signal degradation. At 1310nm wavelength, attenuation is 0.25dB/km, and at 1550nm it reaches 0.35dB/km—ideal for long-haul telecommunications and DWDM applications. Superior Design Features: The SC/UPC to ST/UPC connectors follow Type A to B crossover polarity, the industry standard for duplex patch cords. The 1.8mm outer diameter and riser-rated OFNR jacketing meet fire safety codes for in-building plenum and riser installations. Purple color coding aids in network organization and visual identification. Compliance & Certification: Fully TAA compliant, this cable meets federal procurement requirements for government and educational institutions. RoHS/ELV directive compliance ensures environmental responsibility. Manufactured in Taiwan, the United States, and China with quality oversight at multiple facilities across California, Texas, and South Carolina. Applications & Use Cases: Ideal for data centers, enterprise networks, telecommunications infrastructure, research institutions, and campus networks requiring reliable, standards-compliant fiber connectivity. The 55-meter length bridges moderate distances while custom lengths accommodate specific requirements. Shipping & Support: Enjoy free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty providing peace of mind for your critical network infrastructure investment.
