The JBX43659 90m ST/APC to LC/UPC Simplex Singlemode Fiber Patch Cable is engineered for telecommunications professionals and network administrators requiring reliable, standards-compliant fiber connectivity. This professional-grade cable bridges the gap between ST/APC and LC/UPC connectors, accommodating diverse network architectures and legacy system integrations. **Technical Excellence** Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable exceeds industry performance standards. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB minimize signal degradation, critical for long-distance transmission at both 1310nm and 1550nm wavelengths. Attenuation ratings of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure consistent performance across standard operating ranges. **Regulatory Compliance & Safety** TAA compliant and RoHS/ELV certified, this cable meets government procurement standards and environmental regulations. The riser-rated (OFNR) jacketing provides fire safety compliance for in-building installations. Manufacturing in Taiwan, US, and China with quality control ensures reliability across production sources. **Installation & Identification** The distinctive yellow jacket provides superior visibility during installation, troubleshooting, and maintenance operations. The 1.8mm outer diameter offers flexibility for routing through conduit and cable trays. Straight-through polarity configuration ensures proper signal transmission without specialized adapters. **Warranty & Support** Backed by a 90-day limited warranty, this cable provides peace of mind for critical network deployments. Multiple US shipping locations (Danville CA, Fort Worth TX, Beaufort SC) enable rapid delivery, with free standard shipping on orders exceeding $99. **Custom Solutions Available** Beyond the standard 90m length, custom cable lengths are available to meet specific installation requirements. This flexibility accommodates diverse network topologies and reduces waste from excess cabling. Ideal for data centers, telecommunications facilities, and enterprise networks where reliable fiber connectivity is essential.
