The JBX42432 10-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents a reliable solution for critical fiber optic network infrastructure. Engineered with precision connectors and high-quality optical fiber, this cable delivers the performance telecommunications professionals demand. **Technical Excellence:** This duplex patch cable features a 9/125 singlemode core constructed from G.657.A1 optical glass fiber, providing superior signal fidelity across telecommunications wavelengths. With typical insertion loss of only 0.15dB and maximum attenuation of ≤0.35dB, this cable minimizes signal degradation over the 10-meter span. Return loss exceeds 20dB, ensuring optimal signal reflection characteristics for duplex communication. **Superior Connector Technology:** The FC/APC-to-FC/UPC configuration provides flexible connectivity between equipment using different connector polishing standards. The Type A to B crossover polarity is industry-standard for duplex patch cords, simplifying installation in mixed-vendor environments. Both connector types offer excellent repeatability and durability with thousands of mating cycles. **Robust Construction:** Designed for real-world deployment, the yellow riser-rated (OFNR) jacketing provides flame resistance and environmental protection without compromising flexibility. The compact 1.8mm outer diameter allows routing through tight cable trays and pathways typical of data centers and telecom facilities. **Compliance & Certification:** Fully TAA compliant for government procurement and RoHS/ELV certified per EU directive 2002/95/EC. Performance testing meets ANSI/TIA/EIA-455-171-A specifications, ensuring consistent quality across manufacturing facilities in Taiwan, the United States, and China. **Ideal Applications:** - Data center interconnect patching - Telecommunications backbone networks - FTTH (Fiber to the Home) installations - High-speed LAN environments - Test and measurement setups **Flexible Solutions:** While this product is available in the standard 10-meter length, custom lengths can be ordered to meet specific installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Back your network investments with professional-grade fiber infrastructure backed by comprehensive technical specifications and a 90-day limited warranty.
