The JBX42184 LC/APC to FC/UPC duplex singlemode fiber patch cable represents the pinnacle of optical connectivity solutions for demanding network environments. This 2.5-meter cable bridges two industry-standard connector types, providing seamless integration into existing fiber optic infrastructure. **Superior Technical Performance** Features a precision 9/125 singlemode core engineered for minimal signal degradation. With insertion loss as low as 0.15dB typical and maximum 0.35dB, this cable exceeds telecommunications industry standards. Return loss of ≥20dB ensures signal integrity even in high-speed data transmission. The G.657.A1 bend-insensitive fiber technology accommodates tight radius bends (5mm minimum) without performance compromise, making installation simpler and safer. **Construction and Durability** The robust 1.8mm outer diameter provides optimal balance between flexibility and protection. OFNR riser-rated yellow jacketing enables safe installation in vertical cable runs and building spaces, while maintaining full RoHS compliance and EU directive adherence. The plastic accessory housing protects connectors from dust and environmental contamination. **Applications and Use Cases** Ideal for telecommunications networks, data centers, campus networks, and broadcast facilities. The LC/APC to FC/UPC configuration supports cross-platform connectivity between network equipment from different manufacturers. Duplex design enables full-duplex communication over single cable runs. **Standards and Compliance** Tested per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance metrics. TAA compliance makes this cable suitable for government and enterprise procurement requirements. Manufactured in Taiwan, US, and China with distributed shipping from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC). **Value and Support** Includes 90-day limited warranty. Custom lengths available for specific installation requirements. Free standard shipping on orders over $99. Attenuation specifications: 1310nm at 0.25dB/km, 1550nm at 0.35dB/km provide predictable performance planning for long-distance runs.
