The JBX42979 7-meter LC/UPC to LC/UPC simplex singlemode fiber patch cable represents a premium solution for telecommunications professionals and network engineers requiring reliable, high-performance fiber connectivity. This meticulously engineered cable combines advanced optical specifications with practical design features suitable for both new installations and network upgrades. **Technical Excellence:** Constructed with a 9/125 singlemode fiber core meeting G.657.A1 specifications, this cable delivers industry-leading optical performance. The measured insertion loss of ≤0.35dB at 1550nm (0.25dB/km at 1310nm) ensures minimal signal degradation over the 7-meter span. Return loss exceeding 20dB provides exceptional reflectance characteristics, critical for maintaining signal integrity in sensitive applications. All performance metrics are verified through rigorous testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Robust Construction:** The yellow riser-rated (OFNR) jacket provides flame-resistant protection while maintaining flexibility for installation in conduits and cable trays. The 1.8mm outside diameter accommodates standard patch panel spacing and equipment interfaces. LC/UPC connectors at both ends ensure low-loss connections with return loss ≥20dB, making this cable compatible with virtually all modern networking equipment. **Compliance & Certification:** Fully TAA-compliant for federal procurement requirements, this cable meets RoHS/ELV directives (EU 2002/95/EC), ensuring environmentally responsible manufacturing. The commodity classification and harmonization codes facilitate seamless customs clearance and regulatory compliance. **Ideal Applications:** Perfect for data center backbone connections, fiber-to-the-premises (FTTP) installations, telecommunications equipment interconnection, and enterprise campus networks. The simplex configuration makes it ideal for unidirectional signal paths or applications requiring separate transmit/receive cables. **Shipping & Support:** Enjoy free standard shipping on orders exceeding $99 with availability from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC). Custom lengths are available upon request. Each cable includes a 90-day limited warranty covering manufacturing defects.
