The JBX42989 is a premium 40-meter fiber optic patch cable engineered for telecommunications and data center applications requiring exceptional signal integrity. This simplex configuration cable features LC/UPC connectors on both ends, providing the industry-standard interface for high-speed optical networks. Technical Excellence: Manufactured with 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers performance-grade specifications. Tested for attenuation per ANSI/TIA/EIA-455-171-A-2001 standards, it achieves 1310nm attenuation of 0.25dB/km and 1550nm attenuation of 0.35dB/km. The ≤0.35dB insertion loss and ≥20dB return loss specifications ensure minimal signal reflection and optimal optical efficiency. Compliance & Certification: TAA compliant for government procurement requirements, this cable meets RoHS/ELV directives (EU 2002/95/EC), making it suitable for environmentally conscious and regulated installations. The OFNR riser-rated jacketing provides building code compliance for vertical cable runs in commercial facilities. Design & Durability: The yellow outer jacket enhances cable identification in complex installations, while the 1.8mm outside diameter maintains flexibility for routing in tight spaces. Packaged in protective cases (10x10x10), cables arrive in optimal condition. Applications: Ideal for LAN/WAN interconnections, data center backbones, telecommunications infrastructure, and fiber-to-the-premises (FTTP) deployments. The 40-meter length suits medium-distance connections without signal boosting. Value Proposition: With free standard shipping on orders exceeding $99, custom length availability, and domestic warehousing across multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC), this cable combines performance with accessibility. The 90-day limited warranty provides peace of mind for critical network investments.
