The JBX42994 65-meter LC/UPC to LC/UPC simplex singlemode fiber patch cable represents a premium solution for high-speed data transmission in modern network infrastructures. This cable is engineered to deliver exceptional performance across telecommunications, data centers, and enterprise networking environments. **Technical Excellence** Featuring a 9/125 singlemode fiber core with G.657.A1 glass specifications, this cable provides superior bend-insensitive performance while maintaining industry-leading signal integrity. Attenuation is rigorously tested at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, with insertion loss limited to ≤0.35dB at typical performance levels. The ≥20dB return loss specification ensures minimal signal reflection, critical for high-bandwidth applications. **Compliance & Safety** TAA compliance certifies this cable for government procurement and sensitive installations. RoHS and ELV compliance demonstrates environmental responsibility, while OFNR riser-rated jacketing provides fire safety certification suitable for vertical cable runs in buildings. The 1.8mm outside diameter fits standard cable management systems. **Practical Advantages** The distinctive yellow jacket enhances visibility and organization in complex network installations. Simplex configuration provides single-direction transmission capability for cost-effective point-to-point links. The 65-meter length accommodates mid-range building and campus connectivity without intermediate equipment. **Quality Assurance** All cables are attenuation-tested per ANSI/TIA/EIA-455-171-A-2001 standards. The 90-day limited warranty protects your investment, while multiple US shipping locations (Danville CA, Fort Worth TX, Beaufort SC) ensure fast delivery. Custom length availability accommodates specific installation requirements. **Applications** Ideal for fiber backbone interconnects, server-to-switch connections, telecommunications facilities, laboratory equipment, and broadcast installations requiring reliable singlemode transmission.
