The JBX43539 ST/APC to ST/APC Simplex Singlemode Fiber Patch Cable represents a professional-grade solution for organizations requiring reliable, high-performance fiber optic connectivity. This 90-meter cable is specifically engineered for telecommunications, data center, and enterprise network environments where signal quality and compliance standards are critical. **Technical Specifications:** Built on a 9/125 micron singlemode core with G.657.A1 glass fiber construction, this simplex cable delivers exceptional performance characteristics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal degradation over the full 90-meter span. Return loss of ≥20dB provides excellent signal reflection control, critical for sensitive optical systems. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, with performance validated at both 1310 nm and 1550 nm wavelengths. **Construction and Safety:** The cable features a durable 1.8mm outside diameter jacket rated OFNR (Optical Fiber Non-conductive Riser), making it suitable for vertical runs and general building installations. The bright yellow jacket provides superior visual identification in crowded equipment racks and cable management scenarios, reducing installation errors and improving maintenance efficiency. **Compliance and Certifications:** This cable is TAA (Trade Agreements Act) compliant, meeting federal procurement requirements for government and institutional buyers. RoHS/ELV directive compliance ensures the cable meets environmental and restriction-of-hazardous-substances standards for international distribution. **Applications:** Ideal for point-to-point fiber optic connections in data centers, telecommunications facilities, broadcast environments, and enterprise networks. The simplex configuration efficiently handles unidirectional signal transmission, reducing cable complexity in dedicated transmission paths. **Customization:** While this product is available in standard 90-meter lengths, custom cable lengths are available to match specific installation requirements. Contact our sales team for volume pricing and custom specifications. **Warranty and Support:** Backed by a 90-day limited warranty, this cable includes technical support and free standard shipping on orders over $99.
