The JBX88248 85m ST/ST duplex singlemode fiber patch cable represents a premium solution for telecommunications, data centers, and enterprise network environments requiring reliable long-distance fiber connectivity. This cable combines proven ST connector technology with advanced singlemode fiber specifications to deliver consistent performance in demanding applications. **Key Features:** The cable features a robust 9/125 micron singlemode core constructed from G.657.A1 glass fiber, enabling transmission across extended distances with minimal signal degradation. Its duplex configuration supports bidirectional communication on a single cable run, reducing installation complexity and clutter in cable trays. **Performance Specifications:** Tested to ANSI/TIA/EIA-455-171-A-2001 standards, this cable delivers insertion loss of ≤0.35dB at 1550nm and superior return loss characteristics exceeding 20dB. The typical insertion loss of just 0.15dB ensures maximum signal integrity over the full 85-meter length. **Compliance & Standards:** Fully TAA compliant for GSA Schedule requirements and government procurement. RoHS/ELV certified per EU directive 2002/95/EC, making it suitable for environmentally conscious organizations and international deployments. The riser-rated (OFNR) jacket meets fire safety codes for in-building installations. **Design & Construction:** The distinctive red jacket provides excellent visibility for network identification and organization. With an outside diameter of just 1.8mm, it fits easily through cable conduit and pathways. Type A to B crossover polarity is configured as standard for typical duplex patch cord applications. **Warranty & Support:** Backed by a 90-day limited warranty and available with free standard shipping on orders exceeding $99. Custom lengths available upon request for specialized applications. **Applications:** Ideal for telecommunications infrastructure, campus networks, data center interconnects, and high-speed LAN backbones requiring reliable singlemode connectivity at extended distances.
