The JBX93165 20-meter SC/SC duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Designed to meet the rigorous demands of telecommunications, data centers, and enterprise networking environments, this cable combines precision engineering with proven reliability. **Technical Excellence**: Built with 9/125 singlemode fiber and G.657.A1 glass specifications, the cable delivers exceptional optical performance. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss ≥20dB provides superior signal integrity. Attenuation testing conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 standards guarantees performance at both 1310nm and 1550nm wavelengths (0.25dB/km and 0.35dB/km respectively). **Compliance and Safety**: TAA compliant construction ensures procurement eligibility for government and institutional buyers. The OFNR (Optical Fiber Non-conductive Riser) rating provides fire safety protection suitable for in-building backbone installations. RoHS/ELV directive compliance demonstrates environmental responsibility and regulatory adherence. **Practical Design Features**: The 1.8mm outside diameter provides easy routing through cable trays and conduit systems. SC/UPC connectors with Type A to B crossover polarity represent the industry-standard configuration for duplex patch cords. Orange jacket coloring aids visual identification and organization in complex installations. **Flexibility and Availability**: Beyond the standard 20-meter length, custom lengths are available to suit specific installation requirements. Multiple manufacturing facilities ensure consistent availability and expedited shipping from locations in California, Texas, and South Carolina. Free standard shipping on orders exceeding $99 makes bulk purchasing economical. **Application Versatility**: Ideal for fiber-to-the-desk (FTTD) installations, telecommunications infrastructure, data center interconnects, and telecommunications backbone networks. Suitable for both new installations and maintenance/upgrade scenarios requiring reliable signal transmission. **Quality Assurance**: Backed by a 90-day limited warranty, this cable represents a commitment to long-term performance. The combination of rigorous testing standards, premium materials, and proven SC connector technology ensures years of dependable service in mission-critical applications.
