The JBX42123 SC/APC to SC/UPC duplex fiber patch cable represents a premium solution for mission-critical fiber optic communications. This 2-meter cable combines advanced optical performance with robust construction, making it an ideal choice for telecommunications professionals, data center operators, and network integrators. Optical Performance & Specifications: Built with 9/125 singlemode glass fiber utilizing G.657.A1 technology, this cable delivers exceptional signal integrity across standard telecommunications wavelengths. Measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB ensure minimal signal degradation. The cable supports both 1310 nm and 1550 nm wavelengths with attenuation of 0.25 dB/km and 0.35 dB/km respectively, making it compatible with legacy and modern fiber networks. Durable Construction: The yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides excellent durability and fire resistance suitable for vertical riser applications. With an outside diameter of 1.8mm and housed in protective plastic accessories, the cable withstands demanding installation environments while maintaining signal quality. Connector Configuration: The SC/APC to SC/UPC configuration with Type A to B crossover polarity enables seamless integration with standard duplex fiber infrastructure. This widely-adopted connector combination simplifies installation and reduces compatibility issues in mixed-equipment environments. Compliance & Certification: TAA-compliant status ensures suitability for government and institutional procurements. RoHS/ELV certification demonstrates environmental responsibility and compliance with EU directive 2002/95/EC. Manufacturing in Taiwan, the US, and China provides supply chain flexibility. Applications: Ideal for telecommunications networks, data center interconnects, campus networks, and fiber-to-the-premises (FTTP) installations. The duplex configuration supports bi-directional communication on a single cable run. Customization & Support: Available in custom lengths to meet specific installation requirements. Backed by a 90-day limited warranty and shipped with free standard shipping on qualifying orders from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC).
