The JBX43366 SC/APC to ST/UPC Simplex Fiber Patch Cable represents a critical component for modern fiber optic networks requiring reliable, standards-compliant connectivity. This 4-meter cable bridges the gap between different connector types, making it invaluable for network upgrades, equipment migrations, and heterogeneous system integration. **Technical Excellence:** Built with 9/125 singlemode core fiber and G.657.A1 glass specifications, this cable delivers exceptional signal integrity across the C-band and L-band telecommunications windows. The measured insertion loss of ≤0.35dB ensures minimal signal degradation, while the ≥20dB return loss specification prevents back-reflection artifacts that can compromise system performance. These specifications are validated according to ANSI/TIA/EIA-455-171-A standards, guaranteeing compatibility with enterprise-grade network infrastructure. **Compliance & Durability:** The cable's TAA (Trade Agreements Act) compliance makes it suitable for government, education, and regulated enterprise environments. Its OFNR riser-rated yellow jacket provides flame resistance and easy visual identification in complex installations, while the RoHS/ELV compliance ensures environmental responsibility. The 1.8mm outer diameter allows flexible routing through existing conduits without requiring costly infrastructure modifications. **Practical Applications:** Ideal for data centers, telecommunications facilities, research laboratories, and enterprise campuses, this simplex cable excels in point-to-point signal transmission scenarios. The SC/APC male to ST/UPC male configuration accommodates legacy equipment while meeting modern network standards. Whether upgrading from older ST/UPC infrastructure or integrating SC/APC equipment into existing networks, this cable provides a cost-effective solution. **Shipping & Availability:** Shipped from distribution centers in California, Texas, and South Carolina, orders over $99 qualify for free standard shipping. Custom lengths are available for projects requiring non-standard configurations. The 90-day limited warranty reflects manufacturer confidence in product quality and reliability. **Maintenance & Handling:** As with all fiber optic cables, maintain proper connector cleanliness and avoid excessive bending beyond the cable's minimum bend radius. The plastic accessory components are durable yet lightweight, facilitating easy installation in overhead or wall-mounted configurations.
