The JBX93051 50m LC/SC Duplex Singlemode Fiber Patch Cable represents enterprise-grade optical connectivity solutions designed for mission-critical network applications. Manufactured with precision engineering, this duplex cable features dual fiber strands with 9/125 singlemode core specifications, providing optimal performance for long-distance signal transmission at distances up to 50 meters. **Key Technical Specifications:** Constructed with G.657.A1 glass fiber, this cable delivers exceptional attenuation performance: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensure minimal signal degradation. Each connection has been individually tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Connector Configuration:** The LC/UPC to SC/UPC connector pairing in Type A to B crossover configuration represents the most common industry standard for duplex patch cords, ensuring broad compatibility with existing network equipment. The 1.8mm cable diameter facilitates easy routing and management in crowded cabinet environments. **Compliance & Durability:** TAA compliance, RoHS/ELV directive adherence, and riser-rated (OFNR) jacketing ensure suitability for regulated environments and building codes. The plastic accessory materials and dual-fiber construction provide robust durability for both indoor and outdoor applications. **Ideal Applications:** Perfect for data centers, telecommunications facilities, enterprise networks, and fiber-to-the-desktop deployments where single-mode transmission is required. The 50-meter length accommodates mid-range network architectures without requiring additional amplification. **Custom Solutions Available:** While this product comes in standard 50m length, custom lengths are available upon request to meet specific network requirements. **Warranty & Support:** Backed by a 90-day limited warranty, with fast fulfillment from multiple US distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC). Enjoy free standard shipping on orders exceeding $99. Made with precision manufacturing from Taiwan, US, and China facilities to ensure quality consistency.
