The JBX43322 55-meter SC/APC to FC/UPC simplex singlemode fiber patch cable represents a premium solution for telecommunications, data centers, and enterprise network environments requiring reliable, high-performance fiber connectivity. **Technical Specifications:** This cable features a robust 9/125 singlemode fiber core with G.657.A1 glass composition, ensuring compatibility with modern fiber infrastructure while maintaining superior signal quality. The SC/APC (angled physical contact) to FC/UPC (straight physical contact) configuration accommodates diverse equipment interfaces commonly found in professional networking environments. With an outside diameter of just 1.8mm and low insertion loss of ≤0.35dB (0.15dB typical), this cable minimizes signal degradation over its 55-meter span. **Performance & Compliance:** Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure optimal performance across telecommunications wavelengths. Return loss exceeding 20dB guarantees signal integrity and minimal reflections. The cable meets ANSI/TIA/EIA-455-171-A-2001 standards and carries TAA compliance, making it suitable for government and regulated procurement projects. RoHS/ELV certification confirms environmental compliance. **Design & Durability:** The yellow riser-rated (OFNR) jacket provides flame resistance, visibility in installations, and protection against mechanical damage. This color-coding simplifies network management and troubleshooting. The simplex (single fiber strand) configuration makes this ideal for dedicated unidirectional signal paths or cost-effective point-to-point links. **Flexible Solutions:** Custom lengths are available for specialized installations, and the cable ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) enabling faster delivery. Bulk packaging accommodates enterprise deployments. **Ideal Applications:** Perfect for telecommunications networks, data center interconnects, fiber-to-the-premise (FTTP) installations, and equipment connections requiring single-mode precision over extended distances. The 90-day warranty ensures peace of mind.
