The JBX43020 45-meter LC/APC to LC/UPC simplex singlemode fiber patch cable represents a premium solution for professional-grade fiber optic connectivity. Designed for telecommunications networks, data centers, and enterprise installations, this cable delivers the performance and reliability critical to modern digital infrastructure. Key Technical Specifications: This cable features a 9/125 singlemode core construction, the industry standard for long-distance telecommunications. The G.657.A1 glass fiber designation ensures superior performance and bend-resistant characteristics. With an outer diameter of just 1.8mm, it integrates seamlessly into existing cable management systems while maintaining durability through its OFNR riser-rated yellow jacket. Optical Performance: The cable achieves exceptional optical characteristics with insertion loss of ≤0.35dB at typical conditions (0.15dB) and return loss ≥20dB. Attenuation rates are minimal at both primary wavelengths: 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. These specifications exceed industry standards and are independently verified according to ANSI/TIA/EIA-455-171-A-2001 testing protocols. Connector Configuration: The unique LC/APC to LC/UPC design provides flexibility in network architectures. APC connectors reduce back-reflection, ideal for sensitive applications, while UPC connectors offer broader compatibility. This combination makes the cable suitable for transitional network environments or hybrid installations. Compliance & Certification: Fully TAA compliant for government and institutional procurement. RoHS and ELV certified, ensuring environmental compliance. Available in custom lengths beyond the standard 45-meter specification. Applications & Use Cases: Perfect for interconnecting network equipment, telecommunications infrastructure, data center backbone connections, and long-distance signal transmission. The simplex construction suits point-to-point applications where unidirectional transmission is required. Warranty & Support: Included 90-day limited warranty provides peace of mind. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99.
