The JBX93172 55-meter SC/SC duplex singlemode fiber patch cable is engineered for enterprise-grade network infrastructure, telecommunications facilities, and data center deployments requiring reliable long-distance signal transmission. **Technical Excellence:** This cable features a 9/125 singlemode core with G.657.A1 bend-optimized glass fiber, enabling superior signal propagation while allowing tighter bend radius capabilities. With insertion loss of ≤0.35dB (typically just 0.15dB) and return loss of ≥20dB, the cable meets stringent performance standards for critical network links. Attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal degradation across the full 55-meter span. **Regulatory & Compliance Features:** TAA (Trade Agreements Act) compliant for government and institutional buyers. RoHS/ELV compliant construction meets EU Directive 2002/95/EC environmental standards. OFNR riser-rated jacketing provides fire safety certification suitable for vertical cable runs in commercial buildings. **Design & Durability:** The distinctive orange jacket provides clear visual identification in complex cable environments, reducing installation errors and simplifying maintenance. Duplex configuration with Type A to B crossover polarity supports standard network bridging and equipment interconnection. The 1.8mm outer diameter allows flexible routing without compromising durability. **Tested & Certified:** Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reliable performance verification. Each cable is manufactured to exacting specifications and backed by a 90-day limited warranty. **Applications:** Ideal for connecting network switches, routers, and optical equipment in data centers; extending network reach between building sections; telecommunications infrastructure upgrades; and enterprise-wide fiber backbone installations. **Shipping & Availability:** Free standard shipping on orders exceeding $99. Ships from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC) for expedited delivery. Custom lengths available for specialized installations. Case packaging contains 10 units per 10x10x10 case, suitable for bulk procurement.
