The JBX93197 30-meter SC/ST duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. Designed with precision engineering, this cable delivers reliable single-mode fiber transmission across extended distances, making it ideal for telecommunications infrastructure, data centers, and enterprise networking environments. **Technical Specifications:** This duplex cable features a 9/125 micrometer core specification with G.657.A1 grade glass fiber, supporting both 1310nm and 1550nm wavelengths. The 30-meter length accommodates extensive network installations while maintaining minimal signal degradation. With insertion loss of ≤0.35dB (0.15dB typical) and 20dB return loss, the cable ensures signal fidelity essential for high-speed data transmission. **Connector Configuration:** The SC/UPC to ST/UPC connector arrangement provides Type A to B polarity (crossover), the industry-standard configuration for duplex patch cord applications. This ensures proper signal flow and eliminates installation confusion. **Construction Quality:** The cable's 1.8mm outside diameter and OFNR (riser-rated) jacketing provide both space efficiency and fire safety compliance. RoHS/ELV compliance and EU Directive 2002/95/EC adherence ensure environmental responsibility without compromising performance. **Versatile Applications:** Ideal for transmitting fiber signals across enterprise networks, telecommunications installations, and data center interconnects. The cable's extended 30-meter length makes it suitable for floor-to-floor or building-to-building connectivity where single-mode fiber's superior distance and bandwidth capabilities prove essential. **Compliance & Warranty:** TAA compliance makes this cable suitable for government procurement requirements. Backed by a 90-day limited warranty and tested according to ANSI/TIA/EIA-455-171-A standards, you can trust consistent performance and quality assurance. Custom lengths are available upon request, providing flexibility for unique network architectures.
