The JBX88428 ST/ST Duplex Singlemode Fiber Patch Cable represents a premium solution for organizations requiring reliable, long-distance fiber optic connectivity. This 85-meter cable delivers the performance characteristics demanded by modern data centers, telecommunications facilities, and enterprise network infrastructure. **Technical Excellence:** Constructed with precision-engineered 9/125 micrometer singlemode fiber, this cable achieves minimal attenuation across standard telecom wavelengths—0.25dB/km at 1310nm and 0.35dB/km at 1550nm. The typical insertion loss of just 0.15dB ensures signal integrity over extended runs, critical for applications like CWDM, DWDM, and long-haul transmissions. Return loss specifications exceeding 20dB provide excellent reflection characteristics, minimizing signal degradation. **Build Quality and Compliance:** Featuring G.657.A1 glass fiber construction, this cable offers improved bend radius performance compared to standard G.652.D fiber, enabling more flexible installation in tight spaces. The OFNR (Optical Fiber Non-Conductive Riser) jacketing classification ensures compliance with fire codes and safety standards, making it suitable for vertical cable runs within buildings. TAA (Trade Agreements Act) compliance supports government and federal procurement requirements. **Practical Features:** The Type A to B crossover polarity is the industry-standard configuration for duplex patch cords, ensuring compatibility with most enterprise equipment. ST/UPC connectors provide predictable performance with low reflectance. The protective 1.8mm outer diameter facilitates neat cable management while maintaining durability. **Specifications and Standards:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, this cable meets stringent performance requirements. RoHS and EU directive 2002/95/EC compliance ensure environmental responsibility. Backed by a 90-day limited warranty. **Applications:** Ideal for backbone connections, server room infrastructure, telecommunications facilities, laboratory environments, and any application requiring single-mode fiber transmission over extended distances. The pink coloring aids visual identification in complex cable environments. **Shipping and Availability:** Available in custom lengths upon request. Ships from distribution centers in California, Texas, and South Carolina for rapid delivery. Free standard shipping applies to orders exceeding $99. Professional-grade packaging in 10x10x10 cases ensures damage-free arrival.
