The JBX88362 55-meter ST/ST duplex singlemode fiber patch cable represents a robust solution for professional networking environments requiring long-distance signal transmission with minimal signal degradation. Constructed with premium G.657.A1 glass fiber and featuring a 9/125 core/cladding ratio, this cable delivers superior performance characteristics essential for telecommunications infrastructure and enterprise data center deployments. **Technical Excellence:** This singlemode fiber cable is specifically engineered to minimize attenuation across critical wavelengths, achieving 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB ensure signal fidelity over the full 55-meter span. These specifications exceed standard requirements and provide margin for splices and connections in complex network topologies. **Construction & Durability:** The cable features riser-rated (OFNR) jacketing with a compact 1.8mm outside diameter, balancing protection with space efficiency. The white color facilitates cable identification and organization in busy installations. ST/UPC connectors provide reliable mechanical coupling with low back-reflection characteristics, while the Type A to B crossover configuration accommodates standard duplex patch cord applications. **Compliance & Standards:** Full TAA compliance makes this cable suitable for government and regulated procurement environments. RoHS/ELV certification ensures environmental compliance, while ANSI/TIA/EIA-455-171-A-2001 standards validate attenuation testing methodology. **Practical Applications:** - Long-distance campus network interconnects - Data center backbone connectivity - Telecommunications infrastructure upgrades - Redundant network path provisioning - High-speed signal transmission requirements **Flexibility & Support:** Custom lengths are available for specific deployment requirements, and the 90-day limited warranty provides peace of mind.
