The JBX43082 55-meter LC/APC to SC/UPC simplex singlemode fiber patch cable represents a critical component for modern network infrastructure. Designed to meet the demanding requirements of telecommunications, data center, and enterprise network environments, this cable delivers exceptional performance and reliability. **Technical Specifications:** This singlemode fiber cable features a precisely engineered 9/125 micron core with G.657.A1 glass fiber construction. The cable achieves industry-leading attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, ensuring minimal signal loss over extended distances. Insertion loss testing confirms performance at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB—critical specifications for maintaining signal integrity in high-speed applications. **Connector Architecture:** The LC/APC (Angled Physical Contact) to SC/UPC (Ultra Physical Contact) configuration provides versatile compatibility across diverse network environments. The APC angle on the LC side minimizes back-reflection, while the UPC termination on the SC side offers broad compatibility with existing infrastructure. **Compliance & Certification:** TAA (Trade Agreements Act) compliance ensures government procurement eligibility. RoHS and ELV directives certification guarantees environmental responsibility and material safety. OFNR riser-rating permits safe installation in plenum spaces and vertical cable runs without conduit. **Build Quality:** The 1.8mm outside diameter with plastic accessory materials provides durability without excessive bulk. The bright yellow jacket ensures easy identification and management during installation and maintenance. Case packaging accommodates 10x10x10 configurations for bulk deployments. **Applications:** Ideal for fiber-to-the-desktop implementations, network backbone connections, telecommunications switching centers, and data center interconnects. The 55-meter length suits medium-distance runs within buildings or campus environments. **Availability & Support:** Ships from strategically positioned US warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Custom lengths available for specialized installations. 90-day limited warranty provides peace of mind on your networking investment.
