The JBX43191 9-meter LC/APC to FC/UPC singlemode fiber patch cable is engineered for telecommunications professionals and network infrastructure specialists who demand reliability and precision in fiber optic connectivity. **Technical Specifications:** This simplex cable features a 9/125 micron singlemode fiber core with G.657.A1 glass fiber composition, optimized for long-distance signal transmission at both 1310 nm and 1550 nm wavelengths. With attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, the cable meets stringent performance requirements for telecommunications applications. The insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across connections. **Design & Construction:** The cable features LC/APC and FC/UPC connectors with straight-through polarity configuration. Its 1.8mm outside diameter provides flexibility during installation while maintaining durability, and the yellow OFNR riser-rated jacket offers both visibility in crowded conduit runs and compliance with building safety codes. The plastic accessory components are RoHS/ELV compliant, meeting EU directive 2002/95/EC standards. **Applications:** Ideal for data centers, telecommunications facilities, enterprise networks, and any environment requiring reliable single-mode fiber connections between LC/APC and FC/UPC terminated equipment. Commonly used in backbone connections, equipment interfaces, and test environments. **Quality Assurance:** Manufactured to ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing, with a 90-day limited warranty. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Customization:** Custom cable lengths are available to accommodate specific installation requirements, offering flexibility beyond the standard 9-meter configuration. **TAA Compliance:** Fully compliant with Trade Agreements Act requirements, making this cable suitable for government and federal procurement projects.
