The JBX93189 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade optical connectivity engineered for mission-critical network applications. Designed for telecommunications professionals, data center managers, and IT infrastructure specialists, this 7-meter cable delivers consistent, high-performance fiber signal transmission. **Core Technical Specifications:** Features precision 9/125 singlemode core construction with G.657.A1 glass fiber specifications, ensuring optimal signal propagation across telecommunications wavelengths. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity—the industry-standard setup for duplex patch cord installations. Tested attenuation performance ensures ≤0.35dB insertion loss at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, with return loss exceeding 20dB for superior signal integrity. **Quality Assurance & Compliance:** Every cable undergoes rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. TAA compliance ensures government procurement eligibility. RoHS/ELV directive adherence (EU 2002/95/EC) guarantees environmental responsibility. Backed by a comprehensive 90-day limited warranty covering defects in materials and workmanship. **Design & Construction:** The orange OFNR-rated jacket (1.8mm diameter) provides riser-rated fire performance suitable for building plenum and riser spaces. Duplex configuration enables simultaneous bidirectional transmission—critical for full-duplex networking protocols. Durable plastic accessories ensure long-term reliability in diverse installation environments. **Ideal Applications:** Wireless carrier networks, telecommunications distribution frames, data center interconnects, backbone cabling infrastructure, network equipment rooms, laboratory fiber testing environments, and any installation requiring certified singlemode duplex connectivity. **Availability & Convenience:** Qualifies for free standard shipping on orders exceeding $99. Shipped from strategically located U.S. facilities (California, Texas, South Carolina) for expedited delivery. Custom length options available for specialized installations. Packaged in convenient 10x10x10 case format for inventory management.
