The JBX43521 ST/APC to ST/APC Simplex Singlemode Fiber Patch Cable represents a sophisticated solution for professional optical networking applications requiring single-strand fiber connectivity. This 9-meter cable is manufactured to exacting standards using G.657.A1 singlemode fiber with a 9/125 micron core/cladding ratio, optimized for long-distance, high-bandwidth signal transmission across modern optical networks. Key Technical Specifications: This cable demonstrates exceptional performance characteristics with insertion loss ≤0.35dB at 1310nm (0.15dB typical) and return loss ≥20dB, meeting stringent ANSI/TIA/EIA-455-171-A-2001 standards. The attenuation specification of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensures minimal signal degradation over the 9-meter span, making it suitable for both short-reach and extended-range applications. ST/APC connectors provide angled physical contact design, delivering superior return loss performance compared to standard ST/UPC connectors and reducing back-reflection interference. Construction and Protection: The yellow OFNR (Optical Fiber Non-conductive Riser) jacketing provides flame resistance suitable for indoor riser applications while maintaining excellent flexibility with a 1.8mm outer diameter. The plastic accessory construction ensures lightweight handling without compromising durability. Manufacturing locations across Taiwan, the United States, and China ensure consistent quality control and supply chain reliability. Compliance and Certification: Full TAA (Trade Agreements Act) compliance makes this cable eligible for government and institutional procurement. RoHS/ELV directive compliance (EU 2002/95/EC) confirms environmental responsibility and hazardous substance elimination. The straight-through polarity configuration simplifies installation and eliminates potential connection errors. Applications and Use Cases: Ideal for data center interconnections, telecommunications infrastructure, medical imaging systems, and enterprise network upgrades. The simplex (single-strand) configuration suits unidirectional signal paths or paired installations for bidirectional communication. Available in custom lengths to accommodate specific installation requirements. Warranty and Support: 90-day limited warranty provides protection against manufacturing defects. Free standard shipping on orders exceeding $99, with multiple warehouse locations in Danville CA, Fort Worth TX, and Beaufort SC enabling rapid delivery. Maintenance: Keep connectors clean and capped when not in use. Avoid sharp bends that exceed the cable's minimum bend radius. Store in temperature-controlled environments between -10°C and 60°C.
