The JBX43599 90-meter ST/APC to FC/APC simplex singlemode fiber patch cable represents a professional-grade solution for critical network infrastructure requiring high-performance optical signal transmission. Manufactured to exacting standards and available from multiple North American distribution centers, this cable delivers the reliability that telecommunications professionals demand. **Technical Excellence** This cable features a 9/125 singlemode core optimized for long-distance, high-bandwidth applications. The ST/APC and FC/APC connectors provide secure, low-loss connections essential for telecommunications equipment interconnection. Tested insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation over the 90-meter span. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm align with industry standards for both conventional and DWDM applications. **Installation and Compliance** The bright yellow, riser-rated (OFNR) jacket provides both excellent workplace visibility and fire safety compliance for in-building applications. At 1.8mm outside diameter and constructed from G.657.A1 glass fiber, the cable offers superior bend characteristics without compromising performance. TAA compliance ensures suitability for government and regulated applications, while RoHS/ELV directives confirm environmental responsibility. **Practical Applications** Ideal for connecting telecommunications equipment, network switches, optical networking devices, and DWDM systems where single-mode transmission is required. The extended 90-meter length reduces intermediate connection requirements, improving system reliability while minimizing insertion loss accumulation. **Flexibility and Support** Custom lengths are available upon request, allowing precise tailoring to specific deployment requirements. Backed by a 90-day limited warranty and supported by multiple distribution centers across North America, this cable ensures both rapid deployment and exceptional customer service. Free standard shipping on orders exceeding $99 makes professional-grade fiber connectivity accessible and cost-effective for enterprises and service providers.
