The JBX88367 80-meter ST/ST duplex singlemode fiber patch cable represents enterprise-class connectivity for telecommunications, data centers, and mission-critical network installations. This TAA-compliant optical accessory combines precision engineering with cost-effective performance, making it an ideal choice for network professionals and system integrators. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable delivers superior performance characteristics. The exceptionally low insertion loss (≤0.35dB typical at 1310nm, ≤0.35dB/km at 1550nm) ensures minimal signal degradation over the full 80-meter length. Return loss specifications of ≥20dB guarantee excellent signal integrity. All testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reliability and consistency. **Connector Quality:** ST/UPC connectors feature factory-polished endfaces meeting industry specifications. The Type A to B crossover configuration is optimized for duplex patch cord applications, the most common deployment standard in professional installations. **Installation & Safety:** The 1.8mm outside diameter duplex design with riser-rated (OFNR) jacketing simplifies routing through cable trays and conduit systems. The white jacket provides easy identification and professional appearance in data centers and telecommunications closets. Riser rating enables installation in plenum spaces and vertical risers where fire safety standards demand superior flame-resistance. **Compliance & Warranty:** Full TAA compliance makes this cable suitable for government and institutional procurement. RoHS and EU directive 2002/95/EC compliance demonstrate environmental responsibility. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. All units include 90-day limited warranty. **Applications:** Ideal for telecommunications networks, enterprise data centers, fiber-to-the-premise (FTTP) installations, and any application requiring reliable singlemode signal transmission over extended distances. Custom lengths available for specialized installations.
