The JBX82409 40-meter LC/SC OM1 Multimode Fiber Patch Cable represents an optimal solution for network professionals seeking reliable, standards-compliant fiber connectivity. This duplex patch cable combines robust engineering with practical design features that address real-world installation challenges. **Technical Specifications:** Built on OM1 62.5/125 multimode fiber architecture, this cable delivers consistent performance across standard wavelengths: 3.5 dB/km attenuation at 850nm or 1.0 dB/km at 1300nm. The LC/UPC to SC/UPC connectors feature Type A to B crossover polarity, the industry-standard configuration for duplex patch cords. Testing confirms insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 60dB, ensuring clean signal transmission with minimal reflection. **Design & Durability:** The cable's 1.8mm diameter with bend-insensitive OFNP jacketing combines flexibility with protection. This design enables installation in confined spaces without performance degradation, while the flame-resistant jacketing provides safety compliance for plenum and riser applications. The distinctive yellow jacket facilitates quick identification and tracing in complex network installations. **Compliance & Reliability:** Fully TAA-compliant and RoHS/ELV certified under EU Directive 2002/95/EC, this cable meets government and enterprise procurement standards. Manufacturing across Taiwan, US, and China facilities ensures consistent quality. Each cable ships with a 90-day limited warranty and is independently tested to ANSI/TIA/EIA standards. **Applications:** Ideal for data centers, network closets, server rooms, and campus connectivity. The 40-meter length suits backbone runs and intermediate-distance links without requiring signal regeneration. Compatible with LC and SC connectors across switches, servers, and network equipment. **Ordering & Support:** Available for immediate shipment from warehouses in Danville CA, Fort Worth TX, and Beaufort SC. Custom lengths available upon request. Orders exceeding $99 qualify for free standard shipping. Professional-grade quality at competitive pricing.
