The JBX43719 7-meter SC/APC to LC/UPC simplex fiber patch cable represents a premium solution for organizations demanding superior optical performance and compliance assurance. Engineered with 9/125 singlemode fiber rated to G.657.A1 specifications, this cable excels in long-distance, high-bandwidth telecommunications applications. **Technical Excellence:** This cable achieves exceptional performance metrics with insertion loss of ≤0.35dB at 1310nm and attenuation of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm. The return loss specification of ≥20dB ensures minimal signal reflection, critical for applications involving CWDM/DWDM systems and high-speed Ethernet protocols up to 100 Gbps. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing measurement accuracy and consistency. **Design Features:** The distinctive yellow jacket serves dual purposes: enhancing visibility for network technicians while providing protection via OFNR riser-rated jacketing suitable for in-wall installations. The 1.8mm outside diameter ensures compatibility with standard fiber management systems. SC/APC connectors provide angled physical contact for superior return loss performance, while LC/UPC connectors offer compact design advantages in high-density environments. **Compliance & Certification:** Full TAA compliance ensures eligibility for federal government procurement. RoHS/ELV directive adherence confirms environmental responsibility. Manufactured in Taiwan, United States, or China to ensure quality and reliability. **Applications:** Ideal for data center interconnects, telecommunications networks, FTTH deployments, and broadcast facilities requiring signal transmission across singlemode infrastructure. The simplex configuration suits point-to-point connections requiring unidirectional signal flow. **Customization & Support:** Custom lengths available to meet specific installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery. 90-day limited warranty provides peace of mind investment protection.
