The JBX88210 represents the ideal solution for professionals requiring dependable singlemode fiber connectivity over extended distances. This 45-meter patch cable combines professional-grade performance with practical design, making it suitable for telecommunications networks, enterprise data centers, and carrier-class installations. **Technical Excellence:** Constructed with 9/125 micron singlemode fiber core and G.657.A1 glass composition, this cable delivers superior performance characteristics. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss over the full 45-meter span. The insertion loss rating of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards for high-fidelity signal transmission. **Build Quality & Compliance:** The yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides flame resistance and building code compliance. With a compact 1.8mm outer diameter, the cable routes efficiently through conduit and tight spaces. TAA compliance ensures suitability for government and regulated installations. RoHS/ELV directive adherence confirms environmental responsibility. **Practical Advantages:** ST/UPC connectors with Type A to B crossover polarity provide the most common duplex configuration. The cable is rigorously tested per ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance. Custom length options allow flexibility for specific installation requirements. Ships from multiple U.S. locations for expedited delivery. **Ideal Applications:** - Long-distance LAN/WAN interconnects - Telecommunications backbone installations - Data center fiber runs - Campus network extensions - Mission-critical signal transmission Backed by a 90-day limited warranty and supported by free standard shipping on orders exceeding $99, this professional-grade patch cable represents excellent value for network infrastructure investments.
