The JBX42985 LC/UPC to LC/UPC simplex singlemode fiber patch cable represents enterprise-level connectivity for mission-critical fiber optic networks. This 20-meter cable is engineered with 9/125 G.657.A1 fiber specifications, ensuring optimal performance for both 1310nm and 1550nm wavelengths commonly used in telecommunications and data center infrastructure. Key Technical Features: Constructed with precision LC/UPC connectors rated for straight-through polarity connections, this simplex cable delivers consistent performance with return loss greater than 20dB and minimal attenuation (0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm). The typical insertion loss of 0.15dB ensures maximum signal strength for extended distances and sensitive applications. Durable Construction: The 1.8mm outside diameter outer jacket is OFNR (Optical Fiber Non-conductive Riser) rated, providing fire-resistant properties suitable for vertical cable runs in multi-story buildings and plenum spaces. The bright yellow color offers immediate visual identification in patch panels and equipment racks, reducing installation errors and simplifying troubleshooting. Compliance & Standards: TAA compliant certification ensures this cable meets Buy American requirements for federal and government contracts. RoHS/ELV directives compliance guarantees environmental responsibility and use of approved materials. All specifications are tested and verified to ANSI/TIA/EIA-455-171-A standards, guaranteeing reliability and interoperability. Applications & Use Cases: Ideal for connecting fiber optic equipment in data centers, telecommunications facilities, campus networks, and enterprise installations. The simplex configuration makes it perfect for unidirectional signal transmission or as part of paired duplex installations. Custom lengths available to accommodate specific installation requirements. Warranty & Support: Backed by a comprehensive 90-day limited warranty. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Manufactured to stringent quality standards in Taiwan, US, or China facilities.
