The JBX42204 65-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents a critical infrastructure component for modern telecommunications networks, data centers, and enterprise IT environments. Designed to exceed industry standards, this optical cable delivers reliable, high-speed data transmission over extended distances. **Technical Specifications:** This cable features a precision-engineered 9/125 singlemode fiber core with G.657.A1 glass fiber composition, optimized for both traditional and bend-insensitive applications. The duplex configuration provides simultaneous bidirectional communication across two fiber strands. Insertion loss measures just 0.15dB typical (maximum 0.35dB), ensuring minimal signal degradation, while return loss exceeds 20dB—meeting stringent telecommunications standards. **Performance & Compliance:** Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, with verified performance at 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths. The cable maintains RoHS/ELV compliance and carries TAA certification, making it suitable for government and regulated procurement requirements. The OFNR riser-rated jacket ensures compliance with building codes for commercial installations. **Design Features:** The distinctive yellow jacket aids in visual identification and traceability within complex network environments. At just 1.8mm outside diameter, the cable negotiates tight spaces, cable trays, and conduit runs efficiently. LC/APC connectors on one end and FC/UPC connectors on the other (Type A to B crossover configuration) provide the flexibility required in mixed-vendor environments. **Applications:** Ideal for telecommunications networks, data center interconnects, fiber-to-the-premises (FTTP) installations, broadcast facilities, and enterprise network upgrades. The 65-meter length bridges moderate distances between network equipment, patch panels, and distribution points. **Logistics & Support:** Available in custom lengths to match specific installation requirements. Ships from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty and manufactured to specifications in Taiwan, US, or China.
